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

1.1 This guide outlines the types of chemical effects and matrix effects which are observed in Auger electron spectros-copy. 1.2 Guidelines are given for the reporting of chemical and matrix effects in Auger spectra. 1.3 Guidelines are given for utilizing Auger chemical effects for identification or characterization.

1.1 This test method describes the temperature calibration of differential thermal analyzers and differential scanning calorimeters over the temperature range from -40°C to +2000°C. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.1 This test method covers a procedure for measuring the corrosion to steel induced by sprayed fire-resistive material. 1.2 These SFRMs include sprayed fibrous and cementitious materials applied directly in contact with the structural mem-bers.

1.1 This practice describes a procedure for determining the subacute dietary toxicity of a test substance administered to birds in their daily dict. The LCs0 value time to mortality and slope of the dose response curve may also be derived. 1.2 This practice is applicable to substances that can be mixed uniformly into the diet.

1.1 This practice is suitable for testing the homogeneity of ametal lot or batch (L/B) in solid form by spark atomic emissionspectrometry (Spark-AES). It is compliant with ISO Guide35—Certification of Reference Materials: General and Statis-tical Principles. It is primarily intended for use in the devel-opment of reference materials but may be used in any otherapplication

1.1 This practice covers general procedures necessary for the calibration of magnification of scanning electron micro-scopes. The relationship between true magnification and indi-cated magnification is a complicated function of operating conditions. 2 Therefore, this practice must be applied to each set of standard operating conditions to be used. 1.2 The values stated in SI units
