significance And Use:
All porcelain enamel coatings or glass coatings are by necessity under some degree of compression at room temperature. The desired degree of compression or stress depends upon the type of ware and... View More
scope:
1.1 This test method covers the measurement of the compressive stresses (Note 0) developed by fired porcelain enamels using the loaded-beam method. Note 0Although some may interpret the calculations that are used in this test method as indicating compressive load, it is commonly referred to as compressive stress within the porcelain enamel industry.
1.2 This test method is limited to the use of the loaded-beam method. However, this method includes charts ( and ) that provide for conversion of loaded-beam test results to warp and ring stress values.
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 and health practices and determine the applicability of regulatory limitations prior to use.
