DIN EN IEC 60942:2018 电声学.音响校准器(IEC 60942-2017); 德文版本EN IEC 60942-2018

This standard specifies performance requirements for 3 classes of sound calibrators: class LS (Laboratory Standard), class 1 and class 2. Class LS sound calibrators are normally used only in the laboratory; class 1 and class 2 are considered as sound calibrators for field use. Conformance is demonstrated when a) measured deviations from design goals do not exceed the applicable acceptance limits and b) the uncertainty of measurement does not exceed the corresponding maximum-permitted uncertainty.

This document specifies a set of principles and considerations for digital television products in support of older people and persons with disabilities in addition to mainstream users. The effect of following the principles and considerations as set out in this document is to ensure that the widest range of users can access, understand and use digital television products. These principles and considerations cover four main user profiles such as individuals with hearing impairments, individuals with sight impairments, individuals with mobility impairments and individuals with cognitive impairments.

IEC 60268-3:2018 音响系统设备.第3部分:放大器

This part of IEC 60268 applies to analogue amplifiers, and the analogue parts of analogue/digital amplifiers, which form part of a sound system for professional or household applications. It specifies the characteristics that should be included in specifications of amplifiers and the corresponding methods of measurement. NOTE The methods of measurement for digital amplifiers and similar equipment are given in IEC 61606 [1]1. In general, the specified methods of measurement are those which are seen to be most directly related to the characteristics. This does not exclude the use of other methods that give equivalent results. In general, the methods are based on the simplest measuring equipment which can provide useful results. This does not exclude the use of more complex equipment that can give higher accuracy and/or allow automatic measurement and recording of results. Rated conditions and standard measuring conditions are specified in order to allow measurements to be reliably repeated.
