ITU-R BS.1387-1 SPANISH-2001感知音頻質(zhì)量的客觀測量方法

The ITU Radiocommunication Assembly considering that conventional objective methods (e.g. for measuring signal-to-noise ratio and distortion) are no longer adequate for measuring the perceived audio quality of systems which use low bit-rate coding schemes or which employ analogue or digital signal processing; that low bit-rate coding schemes are rapidly being deployed; that not all implementations conforming to a specification or standard guarantee the best quality achievable with that specification or standard; that formal subjective assessment methods are not suitable for continuous monitoring of audio quality, e.g. under operational conditions; that objective measurement of perceived audio quality may eventually complement or supersede conventional objective test methods in all areas of measurement; that objective measurement of perceived audio quality may usefully complement subjective assessment methods; that, for some applications, a method which can be implemented in real time is necessary.

DIN 1320-2009聲學.術(shù)語

This document specifies the terminology of acoustics. It contains general terms and definitions as well as terms and definitions from other realms of acoustic.

DIN EN 61649-2009魏布爾分析

This International Standard provides methods for analysing data from a Weibull distribution using continuous parameters such as time to failure, cycles to failure, mechanical stress, etc. In this standard, numerical methods and graphical methods are described to plot data, to make a goodness-of-fit test, to estimate the parameters of the two- or three-parameter Weibull distribution and to plot confidence limits. Guidance is given on how to interpret the plot in terms of risk as a function of time, failure modes and possible weak population and time to first failure or minimum endurance.

DIN EN ISO 105-B02-2014紡織品.色牢度試驗.第B02部分:耐人造光色牢度:氙弧燈試驗(ISO 105-B02-2014).德文版本EN ISO 105-B02-2014

This part of ISO 105 specifies a method intended for determining the effect on the colour of the textiles of all kinds and in all forms to the action of an artificial light source representative of natural daylight (D65). The method is also applicable to white (bleached or optically brightened) textiles. This method allows the use of two different sets of blue wool references. The results from the two different sets of references may not be identical.

DIN EN ISO 10808-2011納米技術(shù).在吸入暴露室中測試納米粒子吸入毒性的特征(ISO 10808-2010);德文版本EN ISO 10808-2010

This International Standard specifies requirements for characterization of airborne nanoparticles in inhalation exposure chambers for the purpose of inhalation toxicity studies in terms of particle mass, size distribution, number concentration and composition.

DIN EN ISO 12572-2017建筑材料和制品濕熱性能.水蒸氣擴散特性的測定.杯式法(ISO 12572-2016);德文版本EN ISO 12572-2016

This document specifies a method based on cup tests for determining the water vapour permeance of building products and the water vapour permeability of building materials under isothermal conditions. Different sets of test conditions are specified. The general principles are applicable to all hygroscopic and non-hygroscopic building materials and products, including insulation materials and including those with facings and integral skins. Annexes give details of test methods suitable for different material types. The results obtained by this method are suitable for design purposes, production control and for inclusion in product specifications.
