(1) Sampling time In principle, air sampling is performed on the first day (24h), 3 days (72h), 7 days, (14 ± 1) days and (28 ± 2) days after the start of the test. Air sampling can also be performed at other specified times. (2) Air sampling Sampling can only be performed after the temperature and relative...
a) Normally, the temperature is 23 ℃ ± 2.0 ℃ in the standard environment, and the sample is evenly replaced on the surface of the stainless steel plate or glass plate. Sample replacement amount is 300g / m2 ± 15g / m2 (ring meter) b) The replacement area of the sample is determined by the relationship with...
The xenon lamp aging test chamber uses a xenon arc lamp with full sunlight spectrum to simulate the destructive light waves in different environments, which can provide corresponding environmental simulation and accelerated tests for scientific research, product development and quality control.According to the...
What conditions should you use after purchasing a 1 cubic meter formaldehyde test chamber? Let Huanyi Instruments Co.,Ltd introduce the application conditions of formaldehyde emission climate chamber for you. Ambient temperature:15℃~35℃ Relative...
The requirements for temperature change rates continue to get faster and faster. It is not uncommon to see a 10°C, 15°C, or 20°C/min Figure 3. Standard Humidity Performance change rate specified. By incorporating faster change rates, total test time can be reduced. Products also can be thermally stressed at...
Humidity is probably one of the most misunderstood topics when it comes to environmental test chambers because the relative humidity (RH) percentage is temperature specific. For example, the amount of moisture in the air at 20°C and 50% RH is not the same as 10°C and 50% RH. As the temperature of air is decreased,...
Thermal Shock Test Chamber is a necessary test equipment for metal, plastic, rubber, electronics and other materials industries. For related industries, a thermal shock chamber is essential, but most people do not pay attention to the daily maintenance during use. In fact, routine maintenance is necessary. Let...
The most obvious change of the revised standard GB18580-2017 is the increase in formaldehyde emission limit requirements. The unified formaldehyde emission limit value is 0.124mg / m3, the limit mark is E1, and the original E2 level is cancelled. In addition, the new standard also canceled the formaldehyde release...
The formaldehyde emission climatic chamber method can simulate the use environment of wood products and is a non-destructive test. It has become the most authoritative method for evaluating the formaldehyde emission of wood products. The formaldehyde emission climatic chamber method is usually used as the...
1.The Xenon Weathering Test Chamber can simulate the environmental conditions such as light, morning dew, and limited use. It can be used for anti-aging experiments in industrial coatings, plastics, aluminum panels, paints, and tempered laminated glass for small cars. 2.Technical...
