Действует
Standard Test Method for Thermal Deflection Rate of Spiral and Helical Coils of Thermostat Metal — 5 стр.
Значение и использование

5.1 This test method simulates, to a practical degree, the operation of the thermostat metal coil.

5.2 The thermal deflection properties of a coil may vary from lot-to-lot of thermostat metal material. This method is useful for determining the optimum thickness and length of the material for a given deflection specification.

5.3 This method is useful as a quality test to determine acceptance or rejection of a lot of thermostat metal coils.

Область применения

1.1 This test method covers the determination of the thermal deflection rate of spiral and helical coils of thermostat metal.

1.2 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.

1.3 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 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.

1.4 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.
