This Standard covers igneous rock (granite) plates for use in high accuracy locating, layout, and inspection work. It encompasses new certification, recertification in the field, and recertification after resurfacing. In general, the standard covers any size granite surface...
This part of the standard applies to the testing of granite surface plates as per DIN 876-1 and cast-iron surface plates as per DIN 876-2. It describes the necessary activities.
Circular hardened steel or granite toolmakers' flats up to 200 mm diameter and circular cast iron or granite high precision surface plates 250 and 400 mm diameter. Material, general design, finish, accuracy, cases, packing and marking. Composition of typical steels, cast irons and...
5.1 This plate format is useful for the routine monitoring of culturable, waterborne bacteria in potable and non-potable waters. The significance of finding these bacteria can help with identifying water quality or water system problems or evaluate compliance with maintenance protocols. This...
1.1 This test method covers a laboratory procedure to determine the hot-surface ignition temperature of dust layers, that is, measuring the minimum temperature at which a dust layer will self-heat. The test consists of a dust layer heated on a hot plate.2,3 1.2 Data obtained from this...
1.1 This test method quantitatively determines the effectiveness of various sizes of antimicrobial towelettes in treating hard, non-porous surfaces against Pseudomonas aeruginosa and Staphylococcus aureus. 1.2 This test method may be used to evaluate towelettes for antimicrobial efficacy...
4.1 The thermal resistance of a ceiling system is used to characterize its steady-state thermal performance. 4.2 The thermal resistance of insulation is related to the density and thickness of the insulation. Test data on thermal resistance are obtained at a thickness and density representative of...
