Standard Practice for Conditioning Plastics for Testing - ASTM

The standard, officially titled the " Standard Practice for Conditioning Plastics for Testing ," is a foundational document used in materials science to ensure that plastic specimens are prepared under uniform environmental conditions. Because the physical and electrical properties of plastics are highly sensitive to temperature and humidity, standardizing these variables is critical for obtaining accurate, repeatable, and comparable test results across different laboratories. astm d61821 pdf

: Variations are strictly limited. For example, if a temperature tolerance of is required, the humidity tolerance must be within Standard Practice for Conditioning Plastics for Testing -

: Predict how a material will perform under specific "abnormal" conditions, such as extreme heat or high humidity. For example, if a temperature tolerance of is

While is the technically equivalent international standard, there are notable differences:
