1, samplingSamples should be sampled at the manufacturer's finished product warehouse or sampled from the circulation area.
2, packaging and transportation
The sample should be sealed and packaged, and the sample should be free from chemical contamination or any physical exposure, such as sun exposure and rain.
Care should be taken during transportation to keep the sample package from damage.
3. Storage of samples before the start of the test
Samples should be kept in a package and stored in an indoor environment at a temperature of 23 ° C and a relative humidity of 45%.
Due to the aging of the sample, storage may affect the amount of formaldehyde released from the product. It is recommended to shorten the storage time of the sample as much as possible.
The above description has to minimize the storage time before the test. Due to the different environments, the same sample has different effects under different environments. Therefore, multi-cabin combination can process multiple samples at the same time to avoid cross-contamination of the sample.
