Wind Turbine Generator Systems - Part 11: Acoustic Noise Measurement Techniques
This National Standard of Canada is equivalent to International Standard IEC 61400-11:2002+A1:2006.
1 Scope
This part of IEC 61400 presents measurement procedures that enable noise emissions of a wind turbine to be characterised. This involves using measurement methods appropriate to noise emission assessment at locations close to the machine, in order to avoid errors due to sound propagation,…
Microbiology of food and animal feeding stuffs — General requirements and guidance for microbiologic...
ISO 7218:2007 gives general requirements and guidance/options intended for three main uses:
implementation of ISO TC34/SC9 or TC34/SC5 standards for detection or enumeration of microorganisms;good laboratory practices for food microbiological laboratories (the purpose is not to detail them in this International Standard, manuals are available for that purpose);guidance for accreditation of food…
Leather — Chemical determination of chromic oxide content — Part 3: Quantification by atomic absorpt...
ISO 5398-3:2007 describes a method for the determination of chromium in aqueous solution obtained from leather. This is an analysis for total chromium in leather; it is not compound specific or specific to its oxidation state.
This method describes the determination of chromium by atomic absorption spectrometry and is applicable to leathers which are expected to have chromic oxide contents in…
Leather — Chemical determination of chromic oxide content — Part 4: Quantification by inductively co...
ISO 5398-4:2007 describes a method for the determination of chromium in aqueous solution obtained from leather. This is an analysis for total chromium in leather; it is not compound specific or specific to its oxidation state.
This method describes the determination of chromium by inductively coupled plasma – optical emission spectrometry and is applicable to leathers which are expected to have…
