Dried milk — Determination of nitrate content — Method by cadmium reduction and spectrometry (Screen...
Describes a method, the principle of which consists in dissolving the dried milk in water, precipitating the fat and proteins, filtering and reducing the nitrate to nitrite in a portion of the filtrate by means of zinc powder and cadmium ion.
Determination of plutonium content in plutonium dioxide (PuO2) of nuclear grade quality — Gravimetri...
The plutonium dioxide has to contain less than 0,5 % of non-volatile impurities. The content of these impurities shall be measured and a correction made to allow for them. The method is used to cross-check accountancy analyses of plutonium dioxide for safeguard purposes. Principle of the method, interferences, reagents, apparatus, procedure and expression of results are described.
Installation Code for Lightning Protection Systems
1. Scope
1.1 This Standard covers the protection from lightning of buildings such as residences, places of public assembly, and buildings of a general industrial nature, including structures with explosive or highly flammable contents. It does not cover th e protection of electrical transmission and distribution systems, and communications systems.
1.2 This Standard also contains a…
Specification of requirements for ripe, dry pods of Ceratonia siliqua Linnaeus, such as odour, taste, freedom from living insects and other pests, damaged carobs (see annex A), extraneous matter, moisture content (see annex B); further sampling, methods of test, packing and marking.
Packaging — Complete, filled transport packages — Toppling test
This International Standard specifies a method for carrying out a toppling test on a complete, filled transport package which may be exposed to the danger of toppling during storage, transport and handling. The test may be used to assess the performance of a package in terms of its strength or the protection that it offers to its contents when it is subject to toppling. lt may be performed either…
Carbonaceous materials for the production of aluminium — Calcined coke — Determination of oil conten...
Calcined coke may be treated with different types of oil in order to limit the formation of a dust cloud during loading and transportation. The method specified in this International Standard permits the determination of the loss of mass in calcined coke after elimination of oil adhering to the particles, by extraction with dichloromethane (methylene chloride) in an extraction apparatus.
Fertilizers — Determination of potassium content — Titrimetric method
The method consists in precipitating of potassium ions by an excess of sodium tetraphenylborate (NaTPB) in a weakly alkaline medium, filtrating and determing of the unused NaTPB by back titration with cetyltrimethylammoniumbromide solution. The test solution shall be prepared as specified in ISO 5317 or ISO 7407.
