5.1 The four-ball wear-test method can be used to determine the relative wear-preventing properties of greases under the test conditions and if the test conditions are changed the relative ratings may be different. No correlation has been established between the four-ball wear test...
1.1 This test method covers a procedure for determining the ball-pan hardness number of granular activated carbons. For the purpose of this test, granular activated carbons are those having particles 90?% of which are larger than 80 mesh (180?μm) as determined by Test Method D2862. 1.2 The...
1.1 This specification covers the design, manufacture, and testing of ball joints utilized for accommodating thermal expansion and contraction, or mechanical movement of a pipeline carrying fluid. The ball joints are intended for use in systems operating above 0?°F (18?°C). 1.2 The...
This specification covers protective face guards designed to be attached to a pre-existing helmet for youth baseball. General requirements for protective face guards shall include mechanical strength, durability, flexibility, finish, padding, attachment system, and shall not cause skin irritation....
1.1 This test method covers the determination of corrosion-preventive
Scope is unavailable.
1.1 This test method describes the measurement of the resistance of textile fabrics to bursting using a hydraulic or pneumatic diaphragm bursting tester. This test method is generally applicable to a wide variety of textile products. 1.2 This test method may also be applicable for stretch woven and...
2.1 In many geographic areas there is concern about the effect of falling hail upon solar collector covers. This practice may be used to determine the ability of flat-plate solar collector covers to withstand the impact forces of hailstones. In this practice, the ability of a solar collector cover...
1.1 This test method covers the determination of corrosion-preventive
1.1 This test method covers the determination of softening point of resins using a Mettler cup and ball apparatus, and may, under user-defined conditions, give results comparable to those obtained by Test Methods E28. 1.2 The values stated in SI units are to be regarded as the standard. The...
1.1 A method for determining bat performance by measuring the bat-ball coefficient of restitution (BBCOR), deriving the collision efficiency (ea), and calculating a batted-ball speed (BBS). It is applicable to baseball and softball bats of any construction or material. The test...
1.1 This test method covers the determination of the staining tendency of asphalt and the assignment of a stain index proportional to the extent of staining observed. 1.2 This test method is applicable to asphalts having ring-and-ball softening points of 85?°C [185?°F] or greater. Note 1:...
1.1 These test methods are intended for determining the softening point of hydrocarbon resins, rosin based resins and similar materials by means of an automated ring-and-ball apparatus. Portions are similar in technical content to the automated-apparatus versions of Test Methods D36, E28,...
1.1 These test methods are intended for determining the softening point of resins (including rosin and terpene resins) and similar materials by means of the ring-and-ball apparatus. Note 1: For testing asphalts, tars, and pitches, see Test Method D36. 1.1.1 Test method using the automated...
1.1 A method for determining bat performance by measuring the bat-ball coefficient of restitution (BBCOR) and deriving the bat performance factor (BPF). It is applicable to softball and baseball bats of any construction or material. The method provides a quantitative measure of bat dynamic...
5.1 This test method can be used to determine scuffing temperature limit and the evolution of coefficient of friction of lubricating oils with increasing temperatures for use in tribological contacts in which high-speed vibrational or start-stop motions are present for extended periods of time...
