Ferronickel — Determination of silicon content — Gravimetric method
Specifies a method for the determination of silicon in ferronickel in the range 0,2 to 4,0 % (m/m). Gives principle, reagents, apparatus, sampling and samples, procedure, expression of results and test report.
Common test methods for insulating and sheathing materials of electric cables - Part 4: Methods spec...
Specifies the test methods to be used for testing polymeric
insulating and sheathing materials of electric cables for power
distribution and telecommunications including cables used on ships.
Gives the methods for measurements of the resistance to
environmental stress cracking, for wrapping test after thermal
ageing in air, for measurement of melt flow index and for
measurement of carbon black…
The method consists in precipitating, after hydrolysis if necessary, of orthophosphate ions in the form of quinoline phosphomolybdate, in an acid medium and in the presence of acetone, at approximately 75 °C, followed by filtrating, washing drying and weighing of the precipitate obtained.
Wheat flour and rye flour — General guidance on the drafting of bread-making tests
The guidance follows the standard layout widely used for methods of analysis and thus ensures that no element id left unconsidered by the user when elaborating or drafting a bread-making test. It provides information on the contents of the clauses, such as scope and field of application, principle, ingredients, apparatus, sampling, procedure, expression of results, test report.
Reinforced plastics based on unsaturated polyester resins — Determination of residual styrene monome...
The residual styrene monomer content in reinforced plastics based on unsaturated polyester (UP) resins is an important criterion in evaluating the degree of cure of UP resins in the polymerized state. The determination is carried out by extraction of the residual monomer styrene from the UP resin in the polymerized state using dichloromethane and subsequent gaschromatographic analysis of the…
Dried whey — Determination of nitrate and nitrite contents — Method by cadmium reduction and spectro...
The principle of determination consists in dissolving the dried whey in warm water, precipitating the fat and proteins, filtering and reducing the nitrate in a portion of the filtrate to nitrite by means of copperized cadmium. The sampling shall be made as specified in ISO 707. A figure shows the apparatus for nitrate reduction.
