ASTM B76-26

Standard Test Method for Elevated Temperature Accelerated Life Cycle Testing for Determining Resistance to Oxidation of Nickel-Chromium and Nickel-Chromium-Iron Alloys for Electrical Heating Applications

PUBLISH DATE 2026

ASTM B76-26

1.1 This test method  describes a procedure for determining resistance to oxidation of nickel-chromium and nickel-chromium-iron electrical heating alloys at elevated temperatures under intermittent heating. Procedures for a constant-temperature cycle are provided.

1.2 This test method is only suitable for comparing cyclic oxidation resistance of nickle-chromium and nickel-chromium-iron alloys. It is not suitable for correlation with specific applications in appliances or other industrial heating units or their intended operating conditions.

1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

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 become familiar with all hazards including those identified in the appropriate Safety Data Sheet (SDS) for this product/material as provided by the manufacturer, 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.

3.1 This test method is used by producers of electrical heating alloys to measure the cyclic oxidation resistance of these alloys.

3.2 Because of the effect of the environment, design, and use, the life values obtained from this test method may not correlate with that of an appliance or industrial heating unit.
