Test method of volatile organic compound test chamber for automobile interior parts

1. Reference standard:

HJ/T 4002007 "Method for sampling and determination of volatile organic compounds and aldehydes and ketones in vehicles"

GB/T 27630 "Guidelines for Air Quality Evaluation in Passenger Cars"

2. Test equipment for testing:

Automobile volatile organic compound test chamber, vehicle VOC emission test chamber, automobile interior parts VOC emission test chamber

3. Test purpose:

Test the total emission of organic volatiles from automotive interior materials

4. Characteristics of Volatile Organic Compounds:

The boiling point of highly volatile organic compounds is less than 50°C, such as formaldehyde (6°C), acetaldehyde (20°C)

50℃＜VOC boiling point＜260℃, such as: benzene (80℃), toluene (110℃), xylene (140℃)

260℃＜Semi-volatile organic compounds boiling point＜400℃, such as butyl phthalate (340℃)
