Resistance or voltage values alone do not provide sufficient detail for an engineering evaluation of contact noise. This practice lists the test conditions that should be reported with noise measurements and indicates some conditions (open circuit voltages, currents, etc.) that have been used for quality control and research studies. The use of these practices should provide sufficient detail for an engineering interpretation of the noise data and allow the tests to be repeated by another laboratory. 1.1 This practice describes the practices and factors considered to be most important in the measurement of electrical contact noise of sliding contacts.This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to become familiar with all hazards including those identified in the appropriate Material Safety Data Sheet (MSDS) for this product/material as provided by the manufacturer, to establish appropriate safety and health practices, and determine the applicability of regulatory limitations prior to use.

Specifies a method for the identification of test piece axes in relation to the grain flow, by means of a system of co-ordinates. Applies to both unnotched metal test pieces. The system present is only intended to be applied in situations where a uniform grain flow can be unambiguously indentified (see also 4.2 and the annex).

1.1 These reference photographs are supplied as a means of establishing types and characteristics of surface discontinuities detectable by the penetrant examination methods. They may be used as a reference for acceptance standards, specifications and drawings.1.2 Actual dimensions including maximum length of indications and number of indications per unit area must be specified by the users of this document. No attempt has been made to establish limits of acceptability or the metallurgical cause of a discontinuity.Note 18212;Examples of these reference photographs are shown in Figs. 1-8.

1 This British Standard describes a method for carry-ing out etch inspection of metallic materials and com-ponents and describes some of the widely accepted etching solutions currently in use. 2 The materials covered by the standard are grouped as follows: Ferrous metals (1) Plain carbon, medium and low alloy steels. (2) High alloy (corrosion and heat-resisting) steels. Non-ferrous metals (3) Copper alloys. (4) Aluminium alloys. (5) Magnesium alloys. (6) Titanium alloys. (7) Nickel and cobalt base alloys.
