National standards. British Standards, DIN (Deutsche Industries Normung, from Germany) and ASTM/AISI (American Society for Testing of Materials/American Iron and Steel Institute) are those in most common use for metallic materials. It is always preferable to select a material for which national or international specifications exist. Many materials, including steels and the...

In the case of alloys used in electric heaters the useful life of an alloy is determined (American Society for Testing of Materials, ASTM, B76) by electrically heating a section of wire in air to a given temperature where it is held for two minutes followed by two minutes of cooling. This cycle is repeated until a 10% increase in electrical resistivity is noted and the time is reported as the useful life of the alloy.

As with all materials that have been recently developed, the health risks associated with SiC whiskers are not well known however, because their sizes and shapes are similar to that of asbestos, therefore they are considered hazardous. Airborne dispersion and subsequent inhalation are the most serious health hazards. However, with proper worl lace handling requirements and procedures, large quantities of SiC whiskers can be safely processed. No release of whiskers has been observed from dense ceramic matrix composites during fracture or wear processes. Material Safety Data Sheets (MSDS) are packaged with all products containing loose whiskers and the directions in the data sheets should be followed. At the present time, the American Society for Testing of Materials (ASTM) has developed procedures and handling practice standards for SiC whiskers [14]. 

Apparatus for carrying out these measurements are discussed in Table 5.1. The ATS FAAR teraohmmeter model M 150 E or equivalent is suitable for carrying out these measurements according to American Society for Testing of Materials (ASTM) D1401-02 [1], DIN lEC 60093 [2], and DIN lEC 60167 [3].

The American Society for Testing of Materials (Miller, 1987) has adopted the concept of the MUler number as a measure of the abrasivity of slurries. Standard G-75 describes the relative abrasivity based on the mass loss of a standard 27% chrome white iron block when rubbed in slurry for a particular period of time. To conduct the test and to measure the slurry abrasion response (SAR) number, also called Miller number, a special machine (Figure 10-5) is used. It consists of a wear block driven at 48 strokes per minute with a stroke length of 200 mm (8 in). A dead weight of 2.27 kg [5 lb] is applied to the wear block. At the bottom of the tray, a piece of Neoprene is installed to act as a lap. The tray takes the form of a flat bottom between V-shaped walls that confine the slurry around the block. The tray is filled with sand. The mounted blocks are lowered in the trays. Four, 4-hour tests are conduced and the weight of the block is... 

A variety of materials are available for the lining and manufacture of slurry handling equipment and piping. Various selections are available based on the degree of abrasiveness, corrosion, temperature, and presence of oils or solvents. In terms of measurement of wear, the American Society for Testing of Materials has developed a slurry abrasion response (SAR) number, also called Miller number. It is extremely useful for determining the need to line pipelines and pumps.

The disk surface is thus exposed only to gaseous SO, not particulates. The American Society for Testing of Materials (ASTM) procedure suggests a 30-day exposure, followed by a standard sulfate analysis [16]. The other method sometimes used is the peroxide candle, similar in its function to the chloride candle, but again using lead peroxide to capture SOy In this procedure, a lead peroxide paste is applied to a paper thimble in the laboratory, and allowed to dry thoroughly before exposure. The thimble is then exposed in an instrument shelter to the test yard environment. In both cases, the SOj deposited results are appropriately reported in terms of deposition rate on the surface in units of mg/m /day.
