Electroacoustics. Audio-frequency induction loop systems for assisted hearing - Methods of measuring and specifying the performance of system components1 Scope This part of the IEC 62489 series applies to the components of audio frequency induction loop systems for assisted hearing. It may also be applied to such systems used for other purposes, as far as it is applicable. This standard is intended to encourage accurate and uniform presentation of manufacturers' specifications, which can be verified by standardized methods of measurement. It is intended for type testing. The components considered are

Founding — Malleable cast irons

— acoustic environment

This document applies to rubber and rubber products such as raw materials

BS 1679-8 specifies requirements for materials

BS EN 14423 is useful for the safe designing of clamp type coupling assemblies for steam hoses fittings

BS EN 16995 on the determination of MOSH and MOAH in vegetable oils and foodstuff is useful for:

BS ISO/IEC 29109-2 is the standard that specifies elements of conformance testing methodology

and resource use and efficiency

It also gives the methodology to be used when preparing an extended application

Annex C has been added to define an alternative material variant of the pyrotechnic device/initiator harness connector assembly

5) is applicable to the testing of liquid chemicals

through common syntax and semantics
