Manganese ores and concentrates — Determination of phosphorus content — Extraction-molybdovanadate p...
The method is applicable to products having phosphorus contents from 0,02 to 0,5 % (m/m). ISO 4293 should be read in conjunction with ISO 4297. Specifies principle, reagents, apparatus, sample, procedure and expression of results.
Chemical products for industrial use — General method for determination of iron content — 1,10-Phena...
All the iron(III) present in the test solution is reduced to iron(II) with ascorbic acid. At a pH between 2 and 9 1,10-phenanthroline is added. the measurement of the absorbance of the orange-red complex formed is carried out at the wavelength of maximum absorption (510 nm). The method is applicable to test solutions from which an aliquot portion can be taken containing between 10 and 500 g of Fe…
Defines Canadian content and then gives explanations and examples
of the terms in the definition. 'Canadian content', frequently an
important aspect of the procurement process, is here defined so
that it can be considered from a common understanding.
Butadiene for industrial use — Determination of oxygen and argon in the gaseous phase above liquid b...
The analysis is carried out with a gas chromatograph fitted with a thermal conductivity detector. It can be operated at two temperatures, either at - 78 degrees centigrade or at ambient temperature. At ambient temperature, oxygen and argon are not separate and the method thus only allows the total content of these two gases to be determined. When the operations are carried out at - 78 degrees…
Glucose syrup — Determination of dry matter content — Refractive index method
Determination on an undiluted product, at a specified temperature; calculation of the wanted content by means of tables showing the index as a function of composition, concentration and temperature. The method is also applicable to syrup containing fructose.
Supplement No.2-1982 to CSA Standard CAN3-Z349.1-79 - Dental Terminology and
Definitions
Defines, in both English and French, terminology pertaining to
dental science, dental materials, dental equipment and the
practice of dentistry. Establishes translations of terms between
the two official languages. It is anticipated that additions to
the contents of the standard will be made annually.
Acetone for industrial use — Methods of test — Part 1: General
Gives general instruction and specifies the methods for the determination of density at 20 °C, the determination of dry residue after evaporation on a water bath, the measurement of colour, the determination of distillation range and the determination of water content. International Standards ISO 757/1 to ISO 757/5 cancel and replace ISO Recommendation R 757-1968, of which they constitute a…
Fruit and vegetable products — Determination of dry matter content by drying under reduced pressure ...
The method of determination of dry matter content consists in heating to constant mass, after mixing, of liquid or semi-liquid products spread over an absobent surface, or of pasty products mixed with an inert powder, at 70 °C under reduced pressure. The method of determin of water content consists in entraining of the water in the form of vapour by a volatile solvent immiscible with water,…
Fruit and vegetable products — Determination of mineral impurities content
The method consists in separating of organic matter by flotation and of heavy impurities by sedimentation, incineration of the sediment at approximately 600 °C, and weihing of the residue obtained. It cancels and replaces ISO Recommendation R 762-1968, of which it constitutes a technical revision.
