DIN EN 15483-2009環(huán)境空氣質量.使用FTIR光譜學測量近地面大氣環(huán)境

This European Standard is applicable to open-path absorption measurements of 'concentration ~ path length'product using the Fourier transform infrared (FTIR) technique with an artificial radiation source. It is applicableto the continuous measurement of infrared active organic and inorganic compounds in the gaseous state inambient air using fixed tropospheric open paths up to approximately 1 km in length and provides a spatialaverage.

This part 1 of DIN EN 61996 specifies the minimum performance requirements, technical characteristics and methods of testing, and required test results, for shipborne voyage data recorder (VDR) installations as required by Chapter V of the International Convention for Safety of Life at Sea (SOLAS), as amended. It takes account of IMO resolution A.694 (17) and is associated with IEC 60945. When a requirement in this standard is different from IEC 60945, the requirement in this standard takes precedence. This 2nd edition incorporates amendments according to new IMO requirements included in IMO Resolution MSC.XXX (90).

DIN EN 61996-2-2008船舶導航和無線電通信設備及系統(tǒng).船用航程數據記錄儀(VDR).第2部分:單一航程數據記錄儀(S-VDR).性能要求、測試方法和要求的試驗結果(IEC 61996-2-2007).英文版本EN 61996-2-2008

This part of IEC 61996 specifies the minimum performance requirements, technical characteristics andmethods of testing, and required test results, for simplified shipborne voyage data recorders (S-VDRs) asrequired by IMO MSC.163(78). It takes into account IMO resolution A.694(17) and is associated withIEC 60945. When a requirement in this standard is different from IEC 60945, the requirement in thisstandard takes precedence.NOTE All text of this standard, whose wording is identical to that of IMO MSC.163(78) or A.861(20) is printed in italics, and theResolution and associated performance standard paragraph numbers are indicated in brackets.
