The standards address the same subject matter but "differ in technical content." The most significant difference is that ISO 291 describes only specific temperature and humidity conditions for conditioning and testing, whereas ASTM D618-21 provides a broader framework with more options, including the possibility of conditioning not necessarily to equilibrium.

While ISO 291 is a related standard, remains the definitive, more comprehensive guide for plastics in the North American and international markets. 5. How to Obtain the ASTM D618-21 PDF
