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.
Cranes and lifting appliances — Technical characteristics and acceptance documents
Establishes the form of presentation and content of the documents which a manufacturer should provide with the equipment. Documents give technical information and include acceptance documents for the equipment to facilitate its installation, testing and use. Specimen acceptance documents are given in the annex. Applies to all types defined in ISO 4306-1.
Soils - Moisture-Density Relations Standard Proctor Test
The present standard describes the methods of determining the relation between
the moisture content and the density of soils and soil aggregates when these
are compacted in standard moulds using 2,49 kg rammers dropped a height of 305
mm. Four methods are described herein.
NOTE 1 - The laboratory compaction tests described in this standard generally
provide good measures of optimum…
Oils of sassafras and nutmeg — Determination of safrole and cis- and trans-isosafrole content — Gas ...
A small quantity of the oils is analyzed by gas chromatography under specified conditions on a packed column. The safrole and cis- and trans-isosafrole contents are determined by using the internal standard method. As stationary phase are used polydimethylsiloxane, or polyethylene glycol 20000. Operating temperatures: Oven: isotherm about 100 °C when using polydimethylsiloxane; isotherm about 125…
Oils of thujone-containing Artemisia and oil of sage (Salvia officinalis Linnaeus) — Determination o...
A small quantity of the oils is analyzed under specified conditions. The alpha- and beta-thujone contents are determined by using the internal standard or addition method. As stationary phase are used cyanopropyl methylphenyl methyl silicone, or trifluoropropylmethyl silicone, or polyethylene glycol 1500. Operating temperatures: Oven: isotherm about 100 °C when using cyanopropyl methylphenyl…
Oil of calamus — Determination of cis-beta-asarone content — Gas chromatographic method on packed co...
A small quantity of the oil is analyzed under specified conditions. The cis-beta-asarone contents is determined by using the internal standard or addition method. As stationary phase polyethylene glycol 20000 is used. Operating temperatures: Oven: isotherm about 190 °C. Injection system and detector: about 170 °C.
