1.1This quantitative test method discusses the measurement of the heat of fusion and the melting point of ultra-high molecular weight polyethylene (UHMWPE), and the subsequent calculation of the percentage of crystallinity. The method uses a differential scanning calorimeter and can be performed in the laboratory or in the field.

1.2This test method can be used for UHMWPE in powder form, consolidated form, finished product, or a used product. It can also be used for irradiated or chemically crosslinked UHMWPE.

1.3This test method does not suggest a desired range of crystallinity or melting points for specific applications.

1.4The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.5This 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.

1.6This 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.
