D4209-07 – Standard Test Method Technical Guide
📋 Navigating D4209: Scope and Material Classification
ASTM D4209-07 (Reapproved 2019) serves as a critical selection guide for determining the volatile and nonvolatile content of specific industrial coating materials. As outlined in Section 1.1, this practice specifically covers cellulosics, emulsions, resin solutions, shellac, and varnishes. It is important to note that this standard does not provide a procedure for analyzing the composition of the volatile fraction (Note 1). The standard mandates the use of SI units as the primary standard (Section 1.3), ensuring uniformity across all referenced test methods.
💡 Tip: Always consult the specific standards listed in Section 2. This practice streamlines method selection but does not replace the detailed procedural parameters (e.g., oven temperature, sample weight) found in standards like D2369 or D1259.
