AWPA A4-19 is a standard published by the American Wood Preservation Association (AWPA) outlining methods for sampling wood preservatives. The purpose of this standard is to ensure that wood preservatives are properly sampled and tested to determine their effectiveness and to ensure compliance with regulatory requirements.

The AWPA A4-19 standard provides guidance on:

• Sampling procedures: The standard provides detailed instructions on how to obtain representative wood preservative samples from bulk containers such as drums, tanks or trucks.
• Sample preparation: The standard outlines procedures for homogenizing, blending, and subsampling collected samples to ensure they are representative and suitable for testing.
• Test procedures: The standard specifies the tests that must be performed to determine the properties of wood preservatives such as active ingredient content, pH, viscosity, density and color.
• Reporting procedures: The standard provides guidelines for reporting the results of tests, including units of measurement, precision and accuracy of tests, and methods used to calculate results.

Overall, the AWPA A4-19 standard is an important resource for professionals involved in the manufacture, distribution and use of wood preservatives.
