First, product use

This product is mainly used to simulate different ambient temperature, humidity and air replacement rate conditions. The automotive interior parts materials or products are placed in the test chamber. The gas samples are analyzed by appropriate methods to identify the main pollutants and their concentrations. The change in time is then determined based on the measured concentration to determine the release rate and release characteristics of the automotive interior trim material and product.

Second, the implementation of standards

VDA 276 "VOC test climate box method for automotive interior parts"

GB/T 27630-2011 "Guidelines for Air Quality Assessment in Passenger Cars"

Air conditioning in road vehicles - Part 3: Determination of volatile organic compounds release from vehicle interiors and materials.

ISO 12219-4-2013 "Internal air for road vehicles - Part 4: Methods for the determination of volatile organic compounds emitted from internal parts and materials of vehicles - Chamber method"

ISO 16000-9-2011 "Indoor air - Part 9: Determination of volatile organic compounds in building products and furnishings - Test box method"

ISO 12460-1.2007 "Determination of formaldehyde emission from sheet by 1m3 climate chamber method"
