Problems solved by technology

In the above two methods, samples are replaced by points, which can only test samples of specified size, and cannot sample complex components. Moreover, when the same sample is tested by VDA method or JAMA method, the detected data are different.

Embodiment Construction

[0021] In order to further explain the technical solution of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] see figure 1 As shown, the harmful gas sampling method of automotive interior parts includes the following steps:

[0023] First, take samples: take overall sampling for the automotive interior components assembly, and take test samples from the qualified automotive interior components to ensure that the status and details of the components are consistent with the mass-produced vehicles. Considering that the sample may absorb volatile organic substances that do not belong to itself from the surrounding environment, the time from the completion of sample production to sampling shall not exceed three days. When collecting samples, do not directly touch the sample with fingers or process the sample with a cutting saw that can generate heat (such as a high-speed rotary saw). Clean cotton...

Abstract

The invention discloses a harmful gas sampling method for automotive interior parts. The method includes the steps of extracting samples, putting the samples in a testing bag, collecting harmful gas and the like. The method has the advantages of high operability, high reliability, test data stability and high reproducibility; through integral sampling of an automotive interior part assembly, the defects of big test data differences caused by point replacing surface, difficulty in sampling of parts made of complex materials, and the like are overcome effectively, and contribution of harmful gas content in single parts to a finished automobile can be predicated accurately so as to effectively instruct interior air quality improvement of the finished automobile.

Description

technical field [0001] The invention relates to the control of air quality in automobiles, and more specifically relates to a method for sampling harmful gases of automobile interior parts. Background technique [0002] With the rapid increase of domestic car ownership, more and more attention has been paid to the damage caused by air pollution in cars to the human body. On March 1, 2008, the first domestic standard for detecting air pollution in cars - "Sampling and Determination Methods for Volatile Organic Compounds and Aldehydes and Ketones in Cars" (HJT400-2007) was officially implemented. On March 1, 2012, the "Guidelines for the Evaluation of Air Quality in Passenger Cars" (GB / T27630-2011) was officially promulgated. At present, there are only VOC sampling and limit value evaluation methods for complete vehicles in China, and the VOC control of parts and components is still blank in China. [0003] Current hazardous gas sampling methods are mainly for materials, inc...
