Abstract

|
|
The handling process of car indoor air quality is composed of 2 steps of testing. First, assambly part is tested to find a source of car indoor VOCs. Second, cut sample of unit component is tested to find a source material of VOCs emission. If the source material of VOCs emission is found, it can reduce car and assembly part of VOCs by improving material. As cut sample testing has problem of emission from cut surface to find the source of VOCs, it needs to apply unit components testing method. The aim of study is to evaluate VOCs impact factor of unit components in assembly parts. ISO 12219-5 test method reflects not only material effect but also surface area effect by testing unit component without cutting. The unit components of doortrim and console, were tested by ISO12219-5. And it could figure what unit component is main source of VOCs in assembly. And quantity conversion Factor which gets by testing assembly and unit components can be used to make guideline of ISO 12219-5.
