Description

ASTM D8238-24

Active Standard: Standard Test Method for Immunological Assay to Quantify Extractable Guayule Natural Rubber (GNR) Proteins

ASTM D8238

Scope

1.1 This test method covers an immunological method to determine the amount of protein in Guayule Natural Rubber (GNR) and its products using rabbit antisera specific for Guayule Natural Rubber latex proteins. This immunoassay procedure quantitatively measures the level of GNR proteins in solution using an inhibition format. The samples may include but are not restricted to, gloves or other GNR product extracts, and liquid GNR samples which have been collected in order to measure the protein levels.

1.2 For the purpose of this test method, the range of protein will be measured in terms of microgram to milligram quantities.

1.3 This test method can be used to determine the presence of GNR protein contamination on test items.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
