ASTM D6803-2019 用小环境室对涂料散发的挥发性有机化合物（包括羰基化合物）进行测试与取样规程 Standard Practice for Testing and Sampling of Volatile Organic Compounds (Including Carbonyl Compounds) Emitted from Architectural Coatings Using Small-Scale Environmental Chambers

1.1 This practice describes procedures for testing the emissions of volatile organic compounds (VOCs), formaldehyde, and other carbonyl compounds, from alkyd paint, latex paint, primer, and other architectural coating samples using a small-scale environmental chamber test facility.

1.2 This practice describes the requirements for the chamber test facility, the small-scale test chamber, the clean air supply system, the environmental controls, the environmental monitoring and data acquisition system, and the chamber air sampling system.

1.3 This practice describes procedures for documenting the paint and coating samples and for the handling and storage of these samples including splitting of samples into smaller containers for storage and subsequent testing.

1.4 This practice identifies appropriate substrates to be used for the preparation of test specimens of paints and coatings, as well as procedures for preparing substrates for use.

1.5 This practice provides detailed procedures for preparing test specimens of paint and coating samples.

1.6 This practice generally describes chamber test procedures and chamber air sampling procedures. The details of these procedures are dependent upon the objectives of the test.

1.7 This practice does not recommend specific meth
