Certification for Total Carbon Volatile Test for Car Interior Materials

Total carbon volatile test
Project introduction
With the rapid development of my country's automobile industry, the VOC emissions of automobile interior materials have become increasingly concerned. Environmental protection, health and quiet interior space have always been the eternal goal of the automobile industry. The total carbon volatile test is the determination of the total carbon volatiles (total organic matter volatiles) of car interior materials through instrumental analysis.
Pretreatment
The samples should be transported and stored in aluminum-coated polyethylene bags; sampling should be carried out directly after the samples are received, and the delivery time and sampling time should be fixed; natural compounds (such as cotton, wood, leather, and wool) are dried with calcium chloride for 24 hours, and other substances do not need to be treated, but should be broken into small pieces before weighing.
Sampling
The sample should be taken from the position marked on the material and through the entire cross-section of the sample, and the sample should be broken into small pieces larger than 10mg and less than 25mg. Note that the small pieces cannot be heated. If necessary, another sampling preparation method can be specified on the drawing or in the technical conditions of supply, but it must be marked in the description of the sampling results. Organic substances attached to metal parts, such as paint and adhesive materials, must be mechanically removed before weighing.
Weighing
Generally weigh 2g of sample in a 20ml headspace bottle (at least 3 bottles for each sample). However, the specific sample weight should be based on ensuring that the space left on the top layer is 5ml, such as sponges, foams and other large and light materials.
