GB/T 35457-2017Resilient, textile and laminate floor coverings -- Test method for volatile organic compound (VOC) emissions (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard uses the translation method equivalent to the use of ISO 10580:2010 "Elastic, Textile and Laminate Flooring Volatile Organic Compounds Test Method for (VOC) Release.".

Introduction

The health and comfort of the occupants of the indoor space is conditioned by the indoor climate (especially ventilation, temperature and relative humidity) in the room and Indoor pollutants and other factors. Sources of these contaminants may be extensive. Various international agencies have committed to building product volatility Evaluation of the release of organic compounds (VOCs). Their research results are published in the test report, because these results provide adequate and detailed information has been identified as "quasi-standard norms" literature. The purpose of this standard is to serve those who are committed to protecting consumers from being Learn the harm of contaminated products and prevent negative effects on the body caused by the chemical release of materials (ie, carcinogens, teratogens, irritants, odors) the organization provides guidance. If the requirements of the market for low-release flooring materials are met, the above protection can be effectively implemented to meet the requirements of further protection.

To protect the needs of consumers, many countries and industry organizations have developed different systems for evaluating material release.

This standard refers to the current international testing methods related to VOC emissions from textile, elastic and laminated flooring.

Elastic, textile and laminate flooring Volatile organic compounds (VOCs) Release rate test method

1 Scope

This standard specifies the release of volatile organic compounds (VOCs) per unit area and/or concentration of gaseous VOCs under specified environmental conditions.

Degree of determination of the routine detection method.

This standard covers detection of volatile organic compound emission detection chambers for flexible flooring, textile flooring and laminate flooring.

Explained.

Appendix A describes the release detection module and Appendix B gives an example of the evaluation system.

The detection chamber detects the release of volatile organic compounds from unused (pre-layout) floor covering products before and during testing all of the samples in the process need to be processed. For different flooring products, sampling, transportation and storage procedures have detailed regulations.

It will affect the test data. For each type of product to be inspected, provision shall be made for sample preparation.

Note. Due to the heterogeneous nature of the product, it is necessary to select multiple samples to be tested from the same sample for release testing.
