This specification covers unalloyed molybdenum and molybdenum alloy bar, rod, and wire. The following materials are covered: molybdenum 360, molybdenum 361, molybdenum 363, molybdenum 364, molybdenum 365, and molybdenum 366. These materials shall be manufactured with conventional extrusion,...
1.1 This test method covers the determination of the Knoop indentation hardness of advanced ceramics. In this test, a pointed, rhombic-based, pyramidal diamond indenter of prescribed shape is pressed into the surface of a ceramic with a predetermined force to produce a relatively small,...
This specification covers the basic physical requirements for steel chain-link fence fabric that are aluminum-coated before weaving. Fabrics conforming to this specification shall meet specified requirements for weave form and typical diamond count, size of mesh, size of wire, height of...
This specification covers zinc-coated (galvanized) steel chain-link fence fabric, zinc coated either before or after weaving. The wire shall be woven throughout in the form of approximately uniform square mesh, having parallel sides and horizontal and vertical diagonals of approximately uniform...
This specification covers polyvinyl chloride and other conforming organic polymer-coated steel chain-link fabric, coated before weaving. Fabric produced from three classes of wire coatings are covered as follows: Class I consists of polymer coatings extruded over zinc-coated, aluminum-coated, or...
5.1 The CERCHAR test and associated CAI were developed at a time of more demand for application of mechanical excavation machines at the Laboratoire du Center d' Études et Recherches des Charbonnages de France (CERCHAR) (5). CAI is used to assess the abrasiveness of rock for mechanical excavation....
1.1 This test method covers the determination of the practical adhesion strength and mechanical failure modes of hard (Vickers Hardness HV = 5 GPa or higher), thin (

1.1 This test method covers the hardness testing of cemented carbides by use of a Rockwell hardness tester performing tests in the Rockwell HRA scale (regular scale, diamond indenter, 10 kgf (98.07 N) preliminary test force, and 60 kgf (588.4 N) total test force) in the range of Rockwell 80...
1.1 This test method covers determination of (1) chord modulus of elasticity (Young's) and (2) Poisson's ratio of molded concrete cylinders and diamond-drilled concrete cores when under longitudinal compressive stress. Chord modulus of elasticity and Poisson's ratio are defined in...
4.1 Direct observation of the subsurface by the collection of soil and rock samples is an essential part of investigation for geotechnical and environmental purposes. This guide provides information on the major types of soil and rock sampling devices to assist in selection of devices that are...
All multiple ended sets of points operated by a point machine which share a common detection circuit i.e. do not have separate local detection relays for each point end. Includes: • Crossovers • Switch Diamonds • Slips • Trap Points / Derailers • Ladders • EP Points • Secondary detection (i...
