Specifications for unused synthetic organic esters for electrical purposes
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.

Specification for flexible insulating sleeving - Part 3: Specification requirements for individual t...
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.
Fruits, vegetables and derived products — Determination of carotene content — Part 2: Routine method...
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.
Soils - Moisture-Density Relations Modified Proctor Test
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…
Soils - Moisture-Density Relations Standard Proctor Test
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.

Steel and iron — Determination of phosphorus content — Phosphovanadomolybdate spectrophotometric met...
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).
The method specified for the determination of the sulfur content of hydrocarbons is applicable to products having sulfur contents in the range 0,01 % (m/m) to 5 % (m/m). Samples containing heavy-metal additives interfere with the method. Elements such as silicon, phosphorus, calcium, potassium and halides interfere if present in concentrations of more than a few hundred milligrams per kilogram.
