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...
4.1 The materials covered that must meet ASTM specifications are uranium metal and uranium oxide. 4.2 Uranium materials are used as nuclear reactor fuel. For this use, these materials must meet certain criteria for uranium content, uranium-235 enrichment, and impurity content, as described in...
3.1 This practice is provided to facilitate comparison of physical and mechanical properties of refractory materials by establishing uniform presentation of data. 3.2 Units have been chosen, where possible, to result in numbers of magnitude familiar in the refractories industry, that...
3.1 The dimensions listed in this practice represent the dimensions of rectangular and tapered refractory shapes manufactured and used in the United States. 3.2 The modular concept of dimensions permits a versatile arrangement of bonding during the construction of masonry units.
3.1 The oxidation of silicon carbide refractories at elevated temperatures is an important consideration in the application of these refractories. The product of oxidation is amorphous silica or cristobalite, depending upon the temperature at which oxidation takes place. This oxide...
3.1 This test method provides a rapid, inexpensive method for comparing the corrosion resistance of refractories. The isothermal conditions of this test method represent the most severe static corrosion environment possible at the specified test temperature. This test method is suitable for...
2.1 The disintegration of carbon refractories by alkali attack at elevated temperatures is an important consideration in using these materials for certain applications. Disruption of carbon refractories in the test is sensitive to a number of variables, including alkali concentration,...
1.1 This specification covers brick intended for use as the lining in the fireboxes of residential fireplaces. 1.2 The requirements of this specification apply at the time of purchase. The use of results from testing of brick extracted from masonry for determining conformance or nonconformance to...
3.1 Refractory mortars are used for laying, bonding and coating refractory brick. They become an integral part of the resulting refractory lining or structure. Therefore, such mortars should be selected in order to closely match those of the brick. A classification system is...
1.1 This specification covers dry air-setting refractory mortar for use in laying and bonding refractory brick in ship boiler furnaces and wet air-setting refractory mortar for use in laying refractory brick in stationary boiler furnaces, bright annealing furnaces,...
3.1 The zircon content and bulk density of a zirconia-silica refractory material have important influences on chemical resistance and its satisfactory use in refractory applications. This classification is considered useful for purchase specifications and quality control.
1.1 This test method covers the determination of the linear thermal expansion of rigid solid materials using push-rod dilatometers. This method is applicable over any practical temperature range where a device can be constructed to satisfy the performance requirements set forth in this standard....
1.1 This classification covers alumina and alumina-silicate castable refractories that, when tempered with water, will develop structural strength by chemical action. 1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the...
1.1 This classification covers fireclay and high-alumina plastic refractories and ramming mixes that can be pounded or rammed into place to form a monolithic structure. The terms "plastic" and "ramming mix" are generally intended to describe the workability of the material. In this regard,...
1.1 This classification categorizes machine-made refractory brick defined as chrome, chrome-magnesia, magnesia-chrome, and magnesia brick (see 3.1). It does not cover products made from electrically fused magnesium oxide or products made by fusion casting. Its purpose is to describe classes...
3.1 Granular refractory materials may be either refractory grain raw materials that are used in the manufacture of finished refractory products, or bulk granular refractory materials that are sold, with or without some degree of processing, to refractory consumers...
3.1 Granular refractory materials may be either refractory grain raw materials that are used in the manufacture of finished refractory products, or bulk granular refractory materials that are sold, with or without some degree of processing, to refractory consumers...
1.1 This fire-test-response test method covers the determination under specified laboratory conditions of the combustibility of building materials. Materials passing this test are typically classified as noncombustible materials. 1.2 Limitations of this fire-test response test method are shown...
1.1 This test method covers the determination of refractoriness of all types of refractory mortar by heating a pier of brick laid up with the test mortar to learn whether the prescribed heat treatment causes the mortar to flow out of the joints. 1.2 The values stated in inch-pound...
1.1 These test methods cover a wet and a dry method for sieve analysis of refractory materials. 1.1.1 Wet Sieve Analysis-Water promotes the slaking of clays and helps to separate fine particles, washing them from the larger grains. This method is recommended for use with materials that...
