Control Cable for Low Energy Circuits - 150 V and 300 V
Covers the construction and test of multiple-conductor control
cables for monitoring, data recording, and conveying of
information on low energy circuits. It covers cables having a
voltage rating not exceeding 300 V and cables having a voltage
rating not exceeding 150 V.
Electrical installations of buildings - Part 5: Selection and erection of electrical equipment - Cha...
Contains general data for selection and erection of switchgear and controlgear. It covers devices for protection against indirect contact by automatic disconnection of supply, devices for protection against overcurrent and information about coordination of various protective devices. This second edition is renumbered to fall in line with Part 4 of IEC 364.
Steel and cast iron — Determination of nickel content — Flame atomic absorption spectrometric method
The method is applicable to nickel contents between 0.002 % (m/m) and 0.5 % (m/m). Specifies principle, reagents, apparatus, sampling, procedure, expression of results and test report. Annex A gives additional information on the international co-operative tests, and Annex B represents the precision data graphically.
Documentation — Presentation of title information of series
Describes the elements required for the identification of series and parts thereof and gives rules for the presentation and place of such elements. Its purpose is to enable publishers and editors to identify publications grouped in series, thus facilitating the acquisition and recording of series.
Essential oils — Analysis by gas chromatography on packed columns — General method
The Standard gives detailed information on all recurrent parameters, apparatus, products, methods and formulae for the analysis. In general a small quantity of essential oil is analyzed under specified conditions. If required different constituents are identified from their retention indexes. Quantitative determination of specific constituents is carried out by measurement of peak areas.
Steel and cast iron — Determination of copper content — Flame atomic absorption spectrometric method
The method is applicable to copper contents between 0.004 % (m/m) and 0.5 % (m/m). Specifies principle, reagents, apparatus, sampling, procedure, expression of results and test report. Annex A gives additional information on the international co-operative tests. Annex B includes the graphical representation of precision data.
