Specifies requirements for testing by a appropriate method of test given. Annexes A to C specify methods for determining water, oil and total sulfur contents. Annexes D to G provide important information on and give recommendations relating to the safety and use of the medium.
Iron ores — Determination of water soluble chloride content — Ion-selective electrode method
The method ist applicable to a concentration range of 0,005 to 0,1 % (m/m) of water soluble chloride in natural iron ores, and iron ore concentrates and agglomerates including sinter products. Specifies principle, reagents, apparatus, sampling and samples, procedure, expression of results, and test report. Includes three annexes.
Methods of Testing Petroleum and Associated Products Test for Ethyl
Mercaptan Odourant in Propane...
Intended for the semi-quantitative (i.e. ± 25%) determination of
ethyl mercaptan odourant (within the range of 5 to 85 mg/L) in
liquid propane. It is particularly appropriate to confirm that
recently stenched propane is indeed odourized to the required
level. The method is intended for field application, and may be
suitable for use by non-laboratory personnel after suitable
training. A…
Ground (powdered) paprika — Determination of total natural colouring matter content
The method consists in extracting of the natural colouring matter content with acetone, measuring of the absorbance of the solution obtained using a spectrometer at a wavelength of 460 nm.
This ingredient occurs as natural isoprene rubber (NR), synthetic isoprene rubber (IR), balata and gutta percha, in the total solids of NR or IR latices, in solid raw rubbers or in cured or uncured compounds. The method is applicable to these isoprene rubbers alone or in blends. Milling of the test portion as finely as possible is advisable. 2 tables and 2 figures. Annex for information on…
Cranes — Design principles for loads and load combinations — Part 1: General
Establishes general methods for calculating loads and principles to be used to select load combinations for proof of competence for the structural and mechanical components for cranes as defined in ISO 4306-1. Is based on rigid-body kinetic analysis and elasto-static analysis. Provides the general form, content and range of parameter values for more specific standards and also a framework for…
