Foreword
This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part 1.Structure and drafting rules for standardization documents"
Drafting.
This document replaces GB/T 29899-2013 "Test method for emission of volatile organic compounds from wood-based panels and their products - Small-scale emission test method"
Compared with GB/T 29899-2013, in addition to structural adjustments and editorial changes, the main technical changes are as follows.
--- Changed the scope (see Chapter 1, Chapter 1 of the.2013 edition);
--- Changed the definition of volatile organic compounds and added the definition of total aldehyde and ketone compounds (see Chapter 3,.2013 edition,
chapter);
--- Changed the specimen preparation to sample and specimen, and added the common load rate (see Chapter 6, Chapter 6 of the.2013 edition);
--- Changed the test conditions to test conditions, and added common test conditions (see 7.1.2, 7.1.2 of the.2013 edition);
--- Changed the sampling time to be determined by the test cycle (see 7.4, 7.4 of the.2013 edition);
--- Changed the general rules for air sampling and deleted the sampling clause for formaldehyde (see 7.6, 7.6 of the.2013 edition);
--- Changed the sampling analysis and deleted the formaldehyde analysis clause (see 7.6, 7.7 of the.2013 edition);
--- Added calculation and expression of mass release rate (see 8.3);
--- Small release capsule system and small release capsule system example are merged into general technical conditions for small release capsule system (see Appendix A,
Appendix A and Appendix D of the.2013 edition);
--- Added formaldehyde-DNPH derivatives and revised the chromatographic elution diagram of typical aldehydes and ketones-DNPH derivatives (see Appendix C,.2013
Appendix C of the.2011 edition);
--- Added test conditions for commonly used wood-based panels and their products (see Appendix D).
