Guidelines for the Development of Limit States Design
1. Scope
1.1 This Publication sets forth a recommended common basis for codes and standards for the design and evaluation of civil engineering structures, such as building and industrial structures, bridges, earth and water-retaining structures, towers, chimneys, and poles, with the objective of ensuring an adequate and consistent treatment of safety and serviceability whatever the material…
Deals with general considerations, such as: designation, classification, requirements applicable to all types, some particular requirements, sampling, identification. The transmittance requirements and methods of test for particular uses are given in the International Standards listed in clause 3. Gives functional requirements for the various types used mainly in industry. Applies to all types…
Propan-2-ol for industrial use — Methods of test — Part 1: General
Gives general intructions and specifies the methods for the determination of density at 20 °C, for the determination of boiling range, for the determination of dry residue after evaporation on a water bath, for the measurement of colour, for the determination of water content and of aldehydes and ketones content. International Standards ISO 756/1, ISO 756/2 and ISO 756/3 cancel and replace ISO…
Propan-2-ol for industrial use — Methods of test — Part 2: Determination of acidity — Titrimetric me...
The principle consists in dilution of a test portion with carbon dioxide-free water, titration of the acidity with standard volumetric sodium hydroxide solution, in the presence of phenolphthalein as indicator. The method is applicable to products having an acidity, expressed as acetic acid, equal to or greater than 0,0006 % (m/m).
Rubber compounding ingredients — Carbon black — Determination of sulphur content
Lays down two methods for the determination of the total sulphur content in all types of carbon black for use in the rubber industry: Method A, using an oxygen bomb calorimeter; Method B, using a combustion furnace. The total sulphur content, expressed as a percentage by mass, is given by a formula.
Ethanol for industrial use — Methods of test — Part 11: Test for detection of furfural
The principle consists in the treatment of a test portion with aniline and acetic acid, the presence of furfural leading to the formation of a characteristic red colour. - International Standards ISO 1388/1 to ISO 1377/12 cancel and replace ISO Recommendation R 1388-1970 of which they constitute a technical revision.
Ethanol for industrial use — Methods of test — Part 12: Determination of permanganate time
The principle is based on the addition of a test portion, under specified conditions, of potassium permanganate solution. Determination of the time taken for the colour of this test solution to match that of a cobalt(II) chloride and uranyl nitrate colour standard. - International Standards ISO 1388/1 to ISO 1377/12 cancel and replace ISO Recommendation R 1388-1970 of which they constitute a…
Ethanol for industrial use — Methods of test — Part 9: Determination of esters content — Titrimetric...
The method is applicable to products having esters contents in the range 0.005 % (m/m) to 0.15 % (m/m). The principle consists in the saponification of esters present in a test portion by boiling with excess standard volumetric sodium hydroxide solution; determination of the residual sodium hydroxide, and hence the amount used for saponification, by titration with standard volumetric hydrochloric…
