Petroleum and related products — Determination of sulfur content of automotive fuels — Ultraviolet f...
This document specifies an ultraviolet (UV) fluorescence test method for the determination of the sulfur content of the following products:
— having sulfur contents in the range 3 mg/kg to 500 mg/kg,
— motor gasolines containing up to 3,7 % (m/m) oxygen [including those blended with ethanol up to about 10 % (V/V)],
— diesel fuels, including those containing up to about 30 % (V/V) fatty acid…
Packaging — Conditioning for testing — Part 1: Paper sacks
The principle consists in exposure of empty sacks to a conditioning atmosphere so that a state of temperature and moisture content equilibrium is reached between the sacks and this atmosphere. Conditioning atmospheres ar described by a table. Equipment, procedure and test report are specified.
Rubber — Determination of ash — Part 1: Combustion method
This document specifies three methods for the determination of ash from raw rubbers, compounded rubbers and vulcanizates. The methods are applicable to raw, compounded or vulcanized rubbers of the M, N, O, R and U families described in ISO 1629, except that:
— Method A is not used for the determination of ash from compounded or vulcanized rubbers containing chlorine, bromine or iodine;
— Method B…
Building information modelling (BIM) — Data templates for objects used in the life cycle of assets
This document sets out the principles and structure for data templates for construction objects. It is developed to support digital processes using machine-readable formats using a standard data structure to exchange information about any type of construction object, e.g. product, system, assembly, space, building etc., used in the inception, brief, design, production, operation and demolition of…
Vegetable fats and oils — Isomeric diacylglycerols — Determination of the content and relative amoun...
This International Standard specifies the determination of the degree of isomerization of diacylglycerols in vegetable fats and oils. 1,2-diacylglycerols are transformed to the more stable 1,3-isomers during storage or due to acidic catalyzed reaction.
The mass fraction of 1,2-diacylglycerols can be used as a quality criterion for vegetable fats and oils. The absolute content of diacylglycerol…
Plastics — Polyether polyols and polymer polyols — Determination of aldehydes and ketones
This document specifies the determination of aldehydes and ketones content in Polyether polyols or polymeric polyols by high performance liquid chromatography (HPLC).This document is applicable to the determination of formaldehyde (HCHO), acetaldehyde (CH3CHO), acrolein (CH2=CHCHO) and acetone (CH3COCH3) in polyether polyols or polymeric polyols .For the determination of other carbonyl compounds…
Fertilizers — Determination of ammoniacal nitrogen content — Titrimetric method after distillation
The method consists in distilling of the ammonia from an alkaline solution, absorbing in an excess of standard volumetric sulphuric acid solution and back-titrating with standard volumetric sodium hydroxide solution. It is applicable only in the absence of urea or its derivatives, of cyanamide and of organic nitrogenous compounds.
