1.1 These test methods cover the determination of the following properties of refractory shapes: 1.1.1 Apparent porosity, 1.1.2 Liquid absorption, 1.1.3 Apparent specific gravity, and 1.1.4 Bulk density. 1.2 These test methods are applicable to all refractory shapes except those that...
4.1 This test method was developed for use both by manufacturers as a process control tool for the production of AZS fusion-cast refractories, and by glass manufacturers in the selection of refractories and design of glass-melting furnaces. 4.2 The results may be considered as...
4.1 The true specific gravity of a material is the ratio of its true density, determined at a specific temperature, to the true density of water, determined at a specific temperature. Thus, the true specific gravity of a material is a primary property which is related to chemical and mineralogical...
2.1 This test method provides a guide for evaluating the resistance of refractories in glass-melting furnace superstructures to vapor attack. This test method may also be useful for evaluating refractories in other applications where vapor attack occurs. 2.2 An electric-heated furnace...
1.1 This practice covers the methods of calculating areas, volumes, and linear changes of irregularly shaped refractory specimens. 1.2 The specimens must have a constant cross-sectional area over a length (L). 1.3 The values stated in SI units are to be regarded as the standard. 1.4 This...
4.1 The heat of hydration of a calcium aluminate-based castable is liberated over a short period of time (as compared to portland cement). This makes it easy to measure the heat profile using off-the-shelf thermocouple equipment. 4.2 The heat profile can be used to make inferences about the setting...
1.1 This specification covers the requirements for bare, solid conductor, tungsten and rhenium alloy thermoelements having diameters of 0.127?mm (0.005?in.) to 0.508?mm (0.020?in.) supplied in matched pairs. These thermoelements shall be suitable for use either in bead-insulated, bare-wire...
1.1 This guide covers sampling for prebaked carbon anodes used in the production of aluminum, and details procedures for taking test samples from anode blocks. It covers equipment and procedures for obtaining samples from anode blocks in a manner that does not destroy the block or prevent its...
1.1 This guide covers sampling of carbon cathode blocks used in the production of aluminum, and details procedures for taking samples from single cathode blocks. It covers equipment and procedures for obtaining samples from cathode blocks in a manner that does not destroy the cathode block or...
This specification covers thermal insulating bricks made from fire clay that are used as backup insulation for refractory furnace linings of boiler furnaces. The bricks shall be composed of heat-resistant materials that have been burned or fired to produce the desired density, strength, and...
3.1 The mullite content of an alumina-silica refractory material has an important influence on volume stability, load-bearing properties, and its satisfactory use in refractory applications. This classification is considered useful for purchase specifications and quality control.
3.1 The presence of certain impurities in silica brick tends to lower their refractoriness and service limits. This classification permits those familiar with refractories to predict the refractoriness of silica brick from their alkali and alumina contents.
1.1 This practice covers the firing of specimens made from refractory concretes (castable refractories) in accordance with Practice C862 for cast specimens. The procedure is also recommended for heating rates to be used for high-temperature test methods such as Test Methods C16, C583,...
1.1 This test method covers a procedure for determining the non-fibrous content (shot) of man-made rock and slag mineral fiber insulation. The procedure covers a dry sieve analysis method to distinguish between fiberized and non-fiberized (shot) portions of a specimen of man-made rock and slag...
5.1 Most often determined trace elements in crude oils are nickel and vanadium, which are usually the most abundant; however, as many as 45 elements in crude oils have been reported. Knowledge of trace elements in crude oil is important because they can have an adverse effect on petroleum refining...
1.1 This classification covers machine-made fireclay and high-alumina refractory brick, and its purpose is to set forth the various classes and types of these materials in accordance with their normal and characteristic properties, which are important in their use. 1.2 The values stated in...
4.1 This classification categorizes the defined types of fused-cast refractory blocks and shapes into distinct classes based on mineralogical composition. Such classes have historically been useful for relating the defined types and classes with specific industrial applications and for...
