Significance and Use 5.1 This guide establishes a standard sample preparation method and provides a description of three established and recognized test methods for the determination of endotoxin on medical gloves. If interferences in a sample yield suspect results, a second method should be used. 5.2 This guide is appropriate for testing final product that has been subjected to all processes that could influence the final endotoxin level (either microbial contamination or processing agents/raw materials contaminated with endotoxin). As raw materials and processing conditions vary from lot to lot with regard to these parameters, it is appropriate to test for endotoxin on a routine basis if a product endotoxin claim is to be made (for example, non-pyrogenic). The user may find it beneficial to incorporate endotoxin testing for vulnerable areas of their manufacturing process as an alert mechanism.Scope 1.1 This guide covers a selection of methodologies for the determination of bacterial endotoxin on gloves when such a determination is appropriate. 1.2 As bacteria may continue to grow on non-sterile gloves, reportable endotoxin levels are only appropriate for gloves labeled as sterile. Because most environments contain endotoxin, once a box of gloves is opened and the gloves are manipulated, endotoxin levels will increase making it inappropriate to report endotoxin levels on boxed gloves (ex. examination gloves). This is true even if the box had undergone sterilization prior to distribution. 1.3 This guide may also be appropriate for internal quality control or alert purposes at different stages of manufacturing or during process change evaluations. 1.4 This guide is not applicable to the determination of pyrogens other than bacterial endotoxins. 1.5 The sample preparation method described must be used regardless of the test method selected. This method does not describe laboratory test method validation, analyst qualification, or reagent confirmation. Product-specific validation is addressed. 1.6 The safe and proper use of medical gloves is beyond the scope of this guide. 1.7 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. 1.8 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.
