1.1 These practices cover procedures and requirements for the calibration and verification of displacement measuring systems by means of standard calibration devices for static and quasi-static testing machines. This practice is not intended to be complete purchase specifications for testing machines or displacement measuring systems. Displacement measuring systems are not intended to be used for […]

1.1 This test method is designed to determine the activity of hygienic handwash and handrub (4) agents against transient bacterial flora on hands and is not meant for use with surgical hand scrubs or preoperative skin preps. 1.2 Performance of this procedure requires the knowledge of regulations pertaining to the protection of human subjects.

1.1 These test methods cover the determination of the limiting oxygen (oxidant) concentration of mixtures of oxygen (oxidant) and inert gases with flammable gases and vapors at a specified initial pressure and initial temperature.

1.1 This guide is intended to assist remedial project teams,specifically ecological risk assessors, in identifying data and information options that may be used to perform a screening or complex ecological risk assessment (ERA) at a contaminated site.

1.1 This test method determines the minimum ignition energy of a dust cloud in air by a high voltage spark. . 1.2 The Minimum Ignition Energy (MIE) of a dust-cloud is primarily used to assess the likelihood of ignition during processing and handling. The likelihood of ignition is used to evaluate the need for precautions

1.1 This guide covers suggested procedures for the opera-tion of a calorimetric device designed to obtain temperature and pressure data as a function of time for systems undergoing a physicochemical change under nearly adiabatic conditions. 1.2 This guide outlines the calculation of thermodynamic parameters from the time, temperature, and pressure data recorded by a calorimetric

1.1 This guide covers specimen handling and preparation prior to surface analysis and applies to the following surface analysis disciplines: 1.1.1 Auger electron spectroscopy (AES), 1.1.2 X-ray photoelectron spectroscopy (XPS or ESCA),and

1.1 This practice covers a procedure for determining the impedance of absolute eddy-current probes (bridge-type, air or ferrite core, wire wound, shielded, or unshielded) used for finding material defects in electrically conducting material.This practice is intended to establish a uniform methodology to measure the impedance of eddy-current probes prior to receipt of these probes by

1.1 This practice provides guidelines for acoustic emission (AE) examinations of seamless pressure vessels (tubes) of the type used for distribution or storage of industrial gases. 1.2 This practice requires pressurization to a level greater than normal use. Pressurization medium may be gas or liquid. 1.3 This practice does not apply to vessels in cryogenic

1.1 This test method covers the determination of the mini-mum temperature at which vapors in equilibrium with a liquid (or solid) chemical will be suficiently concentrated to form flammable mixtures in air at atmospheric pressure. This test method is written specifically for determination of the tempera-ture limit of flammability of systems using air as the
