Volatile organic compounds and aldehydes and ketones of interior parts Substance testing method (bag method)

Product name: VOC cabin for interior parts, VOC test cabin for auto interior parts bag method

Meet the standard: CVTC 54072—2015 "Test Method for Volatile Organic Compounds and Aldehydes and Ketones in Vehicle Interior Parts (Bag Method)"

1. This standard specifies the test principles and objects, test equipment and test reagents, sample requirements, test procedures, analysis and data processing, quality control, and test reports for the VOC test method (bag method) of vehicle parts.

2. Scope:

This standard applies to the non-metallic parts in the car compartment that are in contact with the flowing air developed by the SAIC Commercial Vehicle Technology Center.

Manufacturer: Dongguan Huanyi Instrument

3. Test principle:

Put the parts to be tested into a sealed sampling bag and fill it with a proper amount of nitrogen. The sampling bag is heated at a certain temperature for a period of time to disperse the volatile organic compounds in the parts or materials into the gas inside the bag. After heating, use Tenax tube to collect benzene, use thermal desorption instrument gas chromatography mass spectrometry (TD-GC-MS) for qualitative and quantitative analysis; use DNPH tube to collect aldehydes and ketones, use high performance liquid chromatography Instrument (HPLC) for qualitative and quantitative analysis.

4. Test object:

Benzene, toluene, xylene, ethylbenzene, styrene, formaldehyde, acetaldehyde, acrylic, TVOC

5. Test equipment:

The main test equipment required for the test is shown in Table 1

6. Test reagents:

The main reagents required for the test are shown in Table 2
