    Significance and Use

    2.1 The change in resistance with temperature for heating element materials is a major design factor and may influence material selection. The measurement of this change is essential to ensure that heating elements perform as designed. This test method was designed to minimize the effect different manufacturing processes have on resistance change, thereby yielding results that are reproducible.

    1. Scope

    1.1 This test method covers the determination of the change of resistance with temperature of metallic materials for electrical heating, and is applicable over the range of service temperatures.

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

    1.3 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 become familiar with all hazards including those identified in the appropriate Material Safety Data Sheet (MSDS) for this product/material as provided by the manufacturer, to establish appropriate safety and health practices, and determine the applicability of regulatory limitations prior to use.
