A method number without its relevant edition can leave an incomplete technical reference. Confirm what the report used and what the actual requirement calls for.
ASTM's textile-standards catalogue lists identifiable test methods and edition information. ASTM — Textile standards catalogue.
Read the exact reference
For a material evaluation, compare the method designation and relevant version in the requirement and report. Do not assume that similarly named methods or different editions are interchangeable.
Resolve the consequence
Ask the competent laboratory or responsible technical party whether a difference affects the intended conclusion. Preserve the explanation rather than accepting or rejecting the evidence from the year alone. A newer date is not, by itself, a complete applicability assessment.
