The ASTM E1731-2011 (2018) Standard Test Method for the Determination of Non-Volatile Residues in Cleanroom Gloves by Weight Method provides a method for the determination of non-volatile residues in cleanroom gloves by weight method. The test method calculates the total amount of non-volatile residues by heating a glove sample, evaporating the volatile matter in it, and then weighing the amount of residue change. This method is used to evaluate the cleanliness of cleanroom gloves to ensure that they do not pollute the environment when used in a high-cleanliness environment. The standard applies to the quality control of cleanroom gloves, especially in the pharmaceutical, electronics and other industries, to ensure that products meet strict requirements for cleanliness and ensure the safety and stability of the production environment.
