Environmental Inspections

UV Accelerated Aging Test

UV (ulraviolide) survival tests are a test method used to determine the shelf-life of the products made between UVA UVB rays and stability tests. These tests are mainly done to detect and verify the shelf life of many products, including cosmetics and medical products.

TÜRCERT provides accelerated aging test for polymer and plastic materials and products.

It is expected that the UV aging tests are expected to maintain microbiological characteristics of the products during the waiting period on shelves and there is no deterioration in their physicochemical structure.

Accelerated Weather Testing The UV Test Chamber can replicate damage caused by sunlight, rain and dew. The UV aging test is carried out by exposing the material to be tested to a controlled cycling cycle of sunlight and moisture while increasing the temperature.

The test determines how long a material, tool, or equipment you use in your daily life will last for an extended period of time in the external atmospheric environment or under special conditions.

The UV test chamber uses ultraviolet fluorescent lamps to mimic the sun; it also uses a spray to simulate the effect of condensation or moisture. Other areas of aviation, automotive, white goods, scientific research and other testing equipment for schools, factories, military, research-bits and other units.

Application industry (not limited to:)

  • Paint, ink, resin, plastic
  • Printing and packaging, aluminum, adhesives
  • Motorcycle industry, cosmetics,
  • Metal, electronic, electrolysis, drugs etc.

 UV Accelerated Aging Tests

  1. Simulate the sun, rain spray, and condensation to test the material by exposing to sunlight with moisture and temperature, and damage.
  2. Get results evenly that the damage is open for several months after a few days or weeks. Loss includes fading, discoloration, gloss reduction, dust, crack, turbidity, fragility, strength reduction and oxidation.
  3. Reference the test data for the improvement of existing materials or evaluating the effect of changes in product durability and other directions.

Such tests can normally be carried out by keeping the products really waiting. In this test management the products are kept both during normal shelf life and the ambient conditions are changed from time to time. For example, the temperature is increased intermittently to accelerate the process. Stability tests with increasing temperature are called accelerated aging tests. When accelerated aging tests are carried out, the products are exposed to a temperature above the temperature they are exposed to under normal conditions. In this way, the duration of the test is shortened and results are taken in less time.

However, although it is accelerated, performing these tests under normal conditions is a long and difficult method. At this point, UV (ulraviolet) survival tests are preferred to save time.

Ultraviolet rays are generally known as ultraviolet rays. These rays cannot be seen with the naked eye. There are three types of ulraviolithic rays from the sun. The UVA and UVB rays pass through the ozone layer of the earth and reach the earth. UVC rays cannot exceed the ozone layer.

These ultraviolet rays from the sun have different wavelengths and the wavelengths of the rays are measured by devices called nanometers. Humans can normally only see rays between 400 and 700 nanometer wavelengths. They cannot see the rays that remain above and below these values.

740-625 is the red color between nanometers and the rays above these values ​​have larger wavelengths. These rays are called infrared rays. 440-380 is a purple color between nanometers and the rays below these values ​​have smaller wavelengths. These rays are also called ultraviolet rays.

UV aging method is a method used for rapid aging tests. Air speed devices are used for this purpose. Some devices are used to shorten the test times, thus getting a faster test result.

Accelerated Weather UV test

The inner bladder of the room is made of SUS 304 steel plate, while the bladder is imported from high grade stainless steel plate.

The heating mode adopts internal bladder chute type heating with rapid temperature rise and even temperature distribution.

The UV Aging test chamber adopts the black aluminum plate to connect the temperature sensor, in conjunction with the PID SSR control system, and uses the black board temperature gauge to control the heating to ensure a more stable temperature.

The radiometer probe is fixed to prevent frequent removal and removal.

It adopts special UV radiatometer with irradiation amount, high precision display and measurement.

The radiation intensity is not more than 50W / m2.

Lighting and condensation can be controlled independently or alternatively and circularly.

The standard test sample holder contains the 75 × 150mm 2 panel. The test panels are the side walls of the cell. To properly close the compartment, it is important to fill each panel holder with samples or blank panels and replace the panel holders.

In general, the operation systems of these devices are two-stage. First, the ambient temperature, coldness and moisture content of the environment is changed and the weather conditions are created and warm steam is released on the product under test. Generally, the product is allowed to stand for four hours under these conditions. The product is then exposed to ultraviolet (UV) rays for eight hours. At this stage, 50, 100 and 150 hourly aging is realized in the products. In the 50 hourly aging processes, the products are taken from the device and color measurements are made and the test is continued.

UV (ulraviolet) survival tests are frequently used, for example, in synthetic dyestuff tests. Synthetic dyestuffs cause health problems in humans and also destroy the natural environment. For this reason, synthetic dyestuffs are subjected to UV aging tests and their effects on human health are determined in a shorter time.

Another application area of ​​UV aging tests are wood materials used in outdoor areas. Wood building materials used in building exterior surfaces or furniture used in the garden are damaged due to sunlight, heat and humidity. UV aging tests carried out in the laboratory environment are applied ultraviolet rays and solar effect is created. In this way, the results of years of natural effects are obtained in a short time.

In the accelerated aging test, the test period is shortened by exposure to temperatures higher than the normal shelf life temperature and results are obtained in a shorter time.

Our laboratory TÜRCERT carries out detailed UV fast aging tests with a strong technological infrastructure, automation and staff.

Inspection of Radioactive Areas

 Radioactive substances are strong sources of energy. They have properties that make glow from themselves. It is not possible to stop this radiation. Radioactivity is related to the nuclear structure of the atom. A radioactive atom makes the compound it enters into its structure radioactive. The spontaneous decomposition and disintegration of an atom without any effect from outside, and its radiation during this separation is called radioactivity. The radioactivity event was first discovered in 1896. The compounds of radioactive elements also have the same radioactive properties. Therefore, radioactivity is a change in the nucleus that depends only on the nucleus structure of the atom.

The main types of radiation are alpha rays, beta rays and gamma rays. Alpha rays can be absorbed by a thin layer of paper or human skin. Beta streams can be absorbed by a thin layer of metal. Gamma rays can penetrate more solid and thick materials. For example, gamma rays can be absorbed by dense materials such as lead and concrete.

Humans' sense organs cannot detect the presence of radiation. Detection and measurement of radiation is only possible with radiation sensitive devices. Moreover, the measuring devices can measure only the part of the radiation that interacts with the substance, not the entire radiation. Some sources of radiation are natural and some are artificial. Radiation is mainly an energy. Radiation can be obtained from the breathing air, edible food or building materials used in construction. Radiation is a part of the environment in short. Natural radiation sources are cosmic rays coming from space, gamma rays emitted from short half-life radioisotopes in the earth, radioactive elements in the human body and radon gas produced by the decay of radium. Artificial radioactive substances, nuclear precipitation during nuclear bomb trials, radioactive substances emitted in nuclear power generation, radioactive substances used in some consumer products. Radiation applications used in the medical field are concentrated in two points: in image acquisition systems and in the treatment of tumors. In other words, radiation is used in the diagnosis and treatment of diseases.

The industrial use of radiation is quite high. Radiation is used in education and research studies, safety studies and consumer products. Radiation is used in areas such as radiography, radioscopy, density and humidity measurements, process control processes such as density, thickness, weight, level, lightning rod, smoke detector and production of different consumer products.

Radiation exposure has serious hazards to human health and the environment. Radiation carries enough energy to break down DNA. The disintegration of DNA means the death of cells. Irresponsible to the environment, radioactive substances are a great danger to the health of humans, animals and plants. The natural environment and ecological balance are disrupted.

Authorized test and inspection organizations also carry out the inspections of radioactive areas within the scope of environmental inspections. Measurement, testing and inspections carried out by the competent authorities are extremely important. The studies are based on standards and legal regulations published by domestic and foreign organizations.

Industrial Area Inspections

 The industrial sector is simply an industry that produces ready-to-use products from raw materials or semi-processed materials. However, this sector is not as simple as defined. Today, the industrial sector is the main sector that directs the economy of the countries and shows the development level of the countries.

The establishment of an industrial facility depends on the provision of sufficient capital, energy resources, raw material resources, operation and marketing activities, the use of labor and technical personnel and many factors. In our country, the industrial sector shows a serious development with the abundant and varied raw material resources, the presence of mineral and water resources rich in energy production, the emphasis on the conversion of thermal power plants to natural gas and the establishment of new hydroelectric power plants in recent years.

The main industrial sectors in the industrial sector are:

  • Food and beverage industry (this sector in itself flour and bakery products industry, sugar and sugar food industry, milk and dairy products industry, meat and meat products industry, tea industry, canned industry, vegetable oil industry and tobacco and alcoholic beverage industry sectors)
  • Textile (woven), leather and clothing industry
  • Mining Industry
  • Automotive and metalware industry
  • Chemical Industry
  • Stone and soil based industry
  • Forestry products industry

In these industrial areas, many machines and equipments are used in production facilities. These machines and equipment are used in various stages of production, as well as in many stages from transport, packaging, storage, shipment and delivery of products to consumers.

The current regulations on occupational health and safety provide many conditions in order to protect the health and safety of employees. At the same time, many standards are being developed by domestic and foreign organizations. The sole purpose of all these studies is to protect the health of the employees.

Employees are exposed to the dangers posed by the machinery and equipment they use in production, as well as to the noise, vibration, noise, dust and especially chemicals that occur in the environment during their work. Inspection of industrial areas should be carried out regularly in terms of both the safety of employees and the safety of employers.

Authorized test and inspection organizations also carry out industrial area inspections within the scope of environmental inspections.

Regular inspections and inspections have been made mandatory for enterprises operating in industrial areas and are also necessary for both product safety and market surveillance audits. Businesses wishing to send their products to other countries, especially European Union countries, have proved that their products comply with international standards. In this respect, testing, measurement, analysis, inspection and control of industrial products have become a necessity.

On the other hand, in terms of occupational health and safety, the basic requirements of industrial products include not only the production conditions and stages of production, but also the controls and inspections to be carried out at the stage of placing these products on the market after production. The enterprises are obliged to have regular inspections of the used machinery and equipment at least once a year, in the light of the assessments in the risk analysis, unless otherwise stipulated.

Inspection of Industrial Production Areas

 In industrial production companies, all products are designed from scratch or come to life with special engineering studies. In industrial manufacturing companies, customers can order a product that is already in stock in the enterprise stock, and can order some additional features and options for pre-designed but not yet manufactured products. For this reason, industrial production companies focus more on operational efficiency.

Industrial production areas are very wide. From agricultural machinery to medical products, from the automotive sector to the aviation sector, many sectors operating in different characteristics and qualities are entering the industrial production field. As a matter of fact, industrial production areas are inevitably complex. If many published standards and legal regulations are not respected, businesses may encounter unexpected situations. In addition, quality production, efficient production, human health and safety, and even compliance with international regulations are important requirements.

Many authorized test and inspection organizations provide test, measurement, analysis, supervision, inspection and control services in order to ensure the correct and complete operation of the production processes of the enterprises and to avoid any problems both during the production activities and the use of the produced goods. These services cover not only the control of production processes, but also the process of packaging, storing, transporting, dispatching and delivering products to consumers.

Within this framework, many services are provided to enterprises such as material testing, process design, operational support in production facilities, quality control, regular control and inspection of machines and establishment of various management systems.

This is due to the fact that businesses operate more strongly, more efficiently, more profitably and more competitively, and that both products and processes are suitable for industrial production areas, while at the same time complying with applicable regulatory requirements.

Authorized test and inspection organizations also carry out inspections of industrial production areas within the scope of environmental inspections. The main industrial production areas are:

  • Chemicals: One of the sectors that directly affects people's lives is the chemical products sector. In this sector, which is intended to be under strict control with domestic and foreign legal regulations, enterprises are kept under constant examination.
  • Civil engineering and building materials: The construction sector is the driving force of the economy. However, it is one of the most dangerous sectors in terms of people's safety.
  • Forest and paper products: Cost control, performance improvement, sustainability, supply chain management, environmental management and operational risk management are important issues in this sector.
  • Metal and mining industry: These are the sectors with the highest number of occupational accidents. Businesses must further comply with standards and regulations on occupational health and safety.
  • Transport and logistics: This sector also plays an important role in industrial production.

One of the most important issues in industrial production is environmental conditions. Not to pollute the nature and protect the natural environment during activities is a priority for all businesses from the smallest to the largest. Consumers are now more conscious about it.

Hotel and Resort Inspections

People who worked and worked for a whole year deserve a nice holiday, of course. Even if some people turn into search for alternative holidays such as holiday preferences, history and culture holidays, nature holidays, plateau holidays and winter holidays, the sea and sun holidays are at the forefront of many people's holiday understanding for today. They look forward to the summer holiday and throw themselves at hotels and resorts as soon as possible.

The management of hotels and resorts is one of the most important sub-sectors that provide a significant foreign exchange input for the economy of our country, in which the tourism sector develops very rapidly. Parallel to the holiday concept of the people, tourism movements and accommodation needs have always been important as long as the first people existed.

The main factor that produces and offers services in the management of hotels and resorts is human. But without the assets of these businesses, people cannot do anything alone. These assets, starting from the offices and buildings of hotels and holiday villages, refer to a wide range of machines, equipment, systems and all kinds of inputs.

Tourism sector is a service sector. The production, delivery and satisfaction of the people staying in these facilities are actually abstract concepts, and the satisfaction levels of those who benefit from these services differ from each other. But most important of all, the services provided in hotels and holiday villages are important for the health and safety of people.

Facilities must be free from any risks in terms of operational safety and must have safety conditions that will not threaten the safety of people. This issue has a very broad meaning. From the maintenance of elevators used in the facilities, to the fire and security systems, from the security of the pool and sports areas to the hygiene of the kitchens, from the training and experience of the employees to the possible dangers of all kinds of electrical and electronic devices, it is necessary to carry out regular inspections and inspections of all kinds of risks.

Inspections of hotels and resorts by authorized institutions are carried out in accordance with the legal regulations in force and the standards published by domestic and foreign organizations. Accidents in pools and fatalities, people poisoned by meals, accidents caused by electric leakage in disco entertainment, various fires are always caused by the failure of timely inspection and inspection of used machines or equipment. The services provided by hotels and holiday villages are human centered and it is therefore very important to comply with certain standards and criteria.

Authorized test and inspection organizations also carry out hotel and holiday village inspections within the scope of environmental inspections. A few standards considered during these studies are:

  • TS 10082 Business - Accommodation facilities - Hotels with tourism certificate - Classification - General and special rules
  • TS 6915 Business - Accommodation - General rules
  • TS 12436 Fire prevention - General in holiday villages
  • TS ISO / TS 13811 Tourism and related services - Rules for developing environmental conditions for accommodation facilities
