1.1 This test method covers laboratory procedures for de-termining the sliding wear of ceramics, metals, and othercandidate wear-resistant materials using a linear, reciprocatingball-on-flat plane geometry. The direction of the relativemotion between sliding surfaces reverses in a periodic fashionsuch that the sliding occurs back and forth and in a straightline. The principal quantities of interest are […]

1.1 The purpose of this guide is to establish a procedure to select cleaning agents, both solvents and water-based detergents, for oxygen- enriched systems. This includes laboratory-scale tests for cleaning. ffectiveness. materials compatibility, and oxygen compaibility.

1.1 This terminology defines terms related to the compat-ibility and sensitivity of materials in oxygen enriched atmo-spheres. It includes those standards under the jurisdiction of ASTM Committee G04. 1.2 The terminology concentrates on terms commonly en-countered in and specific to practices and methods used to evaluate the compatibility and sensitivity of materials in oxygen. This

1.1 This test method covers a procedure for conducting stress-corrosion cracking tests in an acidified boiling sodium chloride solution. This test method is performed in 25 % (by mass) sodium chloride acidified to pH 1.5 with phosphoric acid. This test method is concerned primarily with the test solution and glassware, although a specific style ofU-bend

1.1 This practice describes the procedure for the preparation of single- and double-sded contaminated malle test coupons for the evaluation of cleaning agents, It is applicable for the evaluation of cleaning agents proposed for the cleaning of oxyen-eniched systems and components. It also is applicable to other syslems where contamination is a concem.

1.1 This practice covers the evaluation of amosphenic galvanic corrosio of any anodie material that can be made into a wine when in conlact with a cathodic maleril that can be made into a threaded rod.

1.1 This guide differs from the usual ASTM standard in that it does not address a specific test. Rather, it is an introductory guide for new users of other standard exfoliation test methods, (sce Terminology G15 for definition of exfoliation). 1.2 This guide covers aspects of specimen preparation, exposure, inspection, and evaluation for conducting exfoliation

1.1 This test method covers a laboratory procedure forconducting an electrochemical reactivation (EPR) test on AISIType 304 and 304L (UNS No. S30400 and S30403, respec-tively) stainless steels. This test method can provide a nonde-structive means of quantifying the degree of sensitization inthese steels (1 , 2, 3). 2 This test method has found wideacceptance in

1.1 This test method’ describes test equipment and tech-niques to determine the impact sensitivity of materials inoxygen under tWo different conditions: (I) in ambient pressureliquid oxygen (LOX) or (2) under pressure-controlled condi-tions in LOX or gaseous oxygen (GOX). It is appicable tomaterials for use in LOX or GOX systems al pressures fromambient to 68.9 MPa
