Introduction
At present, Chinese consumers are more concerned about the green, safety and high quality of products, thus leading our society into the stage of sustained growth of consumer demand and accelerated upgrading of consumption structure. In order to further standardize the production order of furniture industry, improve the environmental protection quality of furniture and protect the health and safety of consumers, GB/T 42996 Guidelines for the control of key chemical substances in furniture is formulated and provides guidance for the detection and control suggestions on key chemical substances in furniture. GB/T 42996 consists of two parts, including:
——Part 1: Wooden furniture; aiming to determine the test methods and control suggestions of key chemical substances in wooden furniture.
——Part 2: Upholstered furniture; aiming to determine the test methods and control suggestions of key chemical substances in upholstered furniture.
Guidelines for the control of key chemical substances in furniture - Part 1: Wooden furniture
1 Scope
This document provides terms and definitions, general, control suggestions and test methods involved in the control of key chemical substances in wooden furniture.
This standard is applicable to the control of key chemical substances in indoor wooden furniture.

For the purposes of this document, the terms and definitions given in GB/T 28202, GB/T 31106-2014, GB/T 35607 and the following apply.
3.1
volatile organic compounds
VOCs
organic compounds emitted from the sample, with a boiling point of 260°C at maximum
[Source: GB/T 31106-2014, 3.1, modified]
3.2
key chemical substances in furniture
volatile organic compounds in furniture that have been proved or confirmed to be toxic to human body and the environment and need to be strictly controlled
4 General
4.1 The emission amount of key chemical substances in wooden furniture affects the concentration of VOCs in ambient air, which is closely related to the health and safety of consumers.
4.2 It is very necessary to control the emission amount of key chemical substances in wooden furniture within the range of tolerable risk.
4.3 This document focuses on the emission amount of key chemical substances in wooden furniture in use.
