GB36246-2018 Plastic Runway TVOC Environmental Test Chamber

1、 Purpose and scope of use

This smallVOCThe release amount environmental testing chamber is mainly used as a sample equipment for measuring the release amount of harmful substances from the surface layer of synthetic materials. It is used to determine the release amount of harmful substances from the surface layer of outdoor synthetic material sports fields in various levels and types of schools, as well as the total volatile organic compounds in the finished products of synthetic material sports field surfaces（TVOC）Testing of the total release of harmful substances such as benzene, toluene, xylene, and ethylbenzene, as well as carbon disulfide and formaldehyde.

This smallVOCThe release volume environmental testing chamber is equipped with two, four, and six standard environmental testing chambers, which can conduct multiple sample tests simultaneously, providing high work efficiency for quality inspection agencies and testing units.

Principle: Place the sample in an environmental testing chamber with specified temperature, humidity, and ventilation conditions. After a certain equilibrium time, determine the harmful substance release amount of the sample by detecting the concentration of harmful substances in the air inside the chamber.
