Specifies methods for determining silica, alumina, titania, iron oxide and oxides of manganese, chromium, calcium, magnesium, sodium, potassium and lithium. It also specifies methods for determining the loss of ignition of magnesite and dolomite, and of refractories based on these raw materials. Annex A describes a method for determining the boron content of magnesites only.

The method is not necessarily suitable for latices from natural sources other than Hevea brasiliensis. It is not suitable for compounded latex or vulcanized latex.

Gives methods of test for the materials defined in IEC 60893-1. The contents of the corrigendum of September 1995 have been included in this copy.

Specifies characteristics of synthetic organic esters intended for use as insulating liquids in transformers and other electrical equipment. Gives general guidance on their properties, safety, storage and disposal, and requirements for packaging, labelling and sampling. Describes test methods to test the physical properties. Specifies required characteristics of synthetic organic esters intended…

The contents of the corrigenda of May 1992 and December 1994 have been included in this copy. It has the status of a horizontal standard in accordance with IEC Guide 108.

Gives the requirements for two types of non-heat-shrinkable sleeving, without defined burning properties, extruded from silicone elastomer. They are distinguished principally by volatile content. Sleeving of this type is normally available in bore sizes up to 25 mm and in a range of wall thickness between 0,1 mm and 2 mm.

Specifies two routine methods: method A is for the determination in products having fat content of less than or equal to 5 % (m/m), method B for products having a fat content of more than 5 % (m/m), the limit of 5 % being arbitrary.

1. OBJECT AND SCOPE OF APPLICATIOn The present standard describes the method to determine the relation between the moisture content and the density of soils and soil aggregates when these are compacted in standard moulds using 4,54 kg rammers dropped a height of 457 mm. Four methods are described herein. NOTE 1 - The laboratory compaction tests described in this standard generally…

1. OBJECT AND SCOPE OF APPLICATIOn 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…

The method is applicable with the following limitations: phosphorus contents between 0,001 0 % (m/m) and 1,0 % (m/m), application ranges and test portions in table 1 depending on the concentration of the interfering elements (arsenic, hafnium, niobium, tantalum, titanium, tungsten).
