Reference can be made to ISO 11357-2 for adescription of the general procedure and definitions. General handling and calibration shall be performed as inISO 11357-2 unless stated otherwise…
4 PrincipleA cylindrical rubber test piece is made to slide over an abrasive sheet of specified abrasive grade at aspecified contact pressure over a given distance. The test piece may be non-rotating or rotating during the test.Abrasion takes place over one of the end surfaces of the cylindrical test piece (see Figure 1). The abrasivesheet…
4.2 Pipe materialWhen tested in accordance with the test method as specified in Table 1, using the indicated parameters, the pipe material shall have characteristics conforming to the requirements given in Table 1.The pipe material shall be tested in the form of a pipe. 4.3 Fitting material When tested in accordance with the test method…
Summary of Test Methods4.1 The resistance or conductance of a material specimen or of a capacitor is determined from a measurement of current or of voltage drop under specified conditions. By using the appropriate electrode systems, surface and volume resistance or conductance may be measured separately. The resistivity or conductivity can then be calculated when…
1.6 This test method is applicable to the measurement of thermal transmission through a wide range of specimen properties and environmental conditions. The method has been used at ambient conditions of 10 to 40°C with thicknesses up to approximately 250 mm, and with plate temperatures from –195°C to 540°C at 25-mm thickness (5, 6).1.7 This…
