    Abstract - (Show below) - (Hide below)

    This test method covers an analytical test for determining the amount of total aqueous extractable protein associated with NR, latex, and elastomeric products.

    Scope - (Show below) - (Hide below)

    1.1This test method covers an analytical test for determining the amount of total aqueous extractable protein associated with NR, latex, and elastomeric products. Water soluble proteins are extracted in a buffer solution and then precipitated to concentrate them and also to separate them from water soluble substances that may interfere with the determination. The extracted protein is redissolved and quantified colorimetrically by the modified Lowry method using a protein standard.

    1.2For the purpose of this test method, the range of protein measurement will be based on the limit of detection and quantitation and recorded in micrograms per dm2 test specimen.

    1.3The test method is designed to be accurate and compatible with the industrial environment.

    1.4Steps are included in this test method to minimize the effects of interfering substances.

    1.5It is recognized that other methods for the analysis of leachable proteins exist and these may be used for routine quality control purposes provided they have been validated and a correlation established against the reference method specified by this test method.

    1.6This test method has not been validated for use with lubricated products such as condoms. Condoms with different lubricants as typically marketed, have not been tested in an ASTM ILS to determine if, and if so to what degree, the lubricant interferes with the assay.

    1.7This 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 and health practices and determine the applicability of regulatory limitations prior to use.
