Description of ASTM-C24 2013ASTM C24 - 09(2013)Standard Test Method for Pyrometric Cone Equivalent (PCE) of Fireclay and High Alumina Refractory MaterialsActive Standard ASTM C24 | Developed by Subcommittee: C08.02 Book of Standards Volume: 15.01 ASTM C24Significance and Use 5.1 The deformation and end point of a cone corresponds to a certain heat-work condition due to the effects of time, temperature, and atmosphere. 5.2 The precision of this test method is subject to many variables that are difficult to control. Therefore, an experienced operator may be necessary where PCE values are being utilized for specification purposes. 5.3 PCE values are used to classify fireclay and high alumina refractories. 5.4 This is an effective method of identifying fireclay variations, mining control, and developing raw material specifications. 5.5 Although not recommended, this test method is sometimes applied to materials other than fireclay and high alumina. Such practice should be limited to in-house laboratories and never be used for specification purposes. 1. Scope 1.1 This test method covers the determination of the Pyrometric Cone Equivalent (PCE) of fire clay, fireclay brick, high alumina brick, and silica fire clay refractory mortar by comparison of test cones with standard pyrometric cones under the conditions prescribed in this test method. 1.2 Units 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. 1.2.1 Exceptions Certain weights are in SI units with inch-pound in parenthesis. Also, certain figures have SI units without parenthesis. These SI units are to be regarded as 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 establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
