Commercially dry virgin cork, ramassage, gleanings, corkwood refuse and corkwaste — Definitions and ...
Applies to material defined in ISO 633 the moisture content of which is not higher than 14 % as determined in accordance with ISO 2386. Gross mass of bales is the size of commercially dry cork including packaging. The type of cork and the name of the exporting country shall be indicated on the bales.
Water quality — Determination of calcium and magnesium — Atomic absorption spectrometric method
The procedure is intended for the analysis of raw and drinking waters and can be used for waters having a calcium content of up to 50 mg/l and a magnesium content of up to 5 mg/l. For samples containing higher concentrations of calcium or magnesium a smaller volume of the sample must be taken for the analysis.
High nitrogen content, straight ammonium nitrate fertilizers — Determination or oil retention
The result of the method is a measure for the porosity of the material. The method is applicable to substances which do not contain materials soluble in gas oil and which are prilled or granular. It consists in total immersing of a test portion in gas oil for a specified period, followed by the draining away and the removal of surplus gas oil under specified conditions, and measuring of the…
Fruits, vegetables and derived products — Determination of zinc content — Part 1: Polarographic meth...
The method consists in ashing of a test portion in a muffle furnace at 525+25 C, treating the ash obtained with hydrochloric acid, neutralizing with ammonia solution and determing of the value using an ammonia/ammonium chloride electrolyte. Copper, tin, lead and cadmium do not interfere.
Aluminium ores — Determination of phosphorus content — Molybdenum blue spectrophotometric method
The method is applicable to materials having phosphorus contents, expressed as diphosphorus pentoxide between 0,01 and 5 % (m/m). The arsenic content of the sample does not affect the determination. Specifies principle, reagents, apparatus, sampling and samples, procedure, expression of results and test report. An annex shows the flowsheet of the procedure for the acceptance of test results.
The method is applicable to products having aluminium contents, expressed as aluminium oxide, in the range 30 to 65 % (m/m). Specifies principle, reagents, apparatus, sampling and samples, procedure, expression of results and test report.
The method can be applied to samples containing hydroquinone in the concentration range of 200 to 4000 g/l. Aminophenols and phenylenediamines should also be determined by this method.
Identification of Medical Gas Containers, Pipelines and Valves
Specifies the code for the ready identification of the contents
of portable medical gas containers and pipelines by name, symbols
and colours, and for the ready identification of valve outlets by
a non-interchangeable system. Colour coding requirements do not
apply to liquid oxygen systems for home care use or bulk gas
carriers and/or containers.
