Standard Practice for Spraying, Sampling, Packaging, and Test Specimen Preparation of Spray Polyurethane Foam (SPF) Insulation for Testing of Emissions Using Environmental Chambers

Importancia y uso:

5.1 Manufacturers of SPF insulation may need to test their products for vapor-phase emissions of volatile and semi-volatile organic compounds in order to comply with voluntary standards, purchase specifications, or other requirements.

5.2 Since SPF insulation is formed by chemical reaction when combining a two-component mixture during spraying, specialized equipment and procedures are needed to reproducibly create representative samples suitable for emission testing.

5.3 SPF insulation product manufacturer’s specifications and instructions must be followed carefully and detailed information regarding the spraying process must be recorded (see 7.3). Other precautions regarding handling and shipping are needed to ensure that the chemical integrity of the samples is preserved to the extent possible by practical means (see 7.5).

5.4 Laboratories must prepare representative test specimens from samples of SPF insulation in a consistent manner so that emission tests can be reproduced and reliable comparisons can be made between test data for different samples.
