ISO/TS 17383:2014 describes the procedure for the capillary gas chromatographic determination of the qualitative and semi-quantitative composition of individual triglycerides of fats, oils, and fat mixtures. The separation of the triglycerides is based on their retention depending on the carbon number of the fatty acids in the triglycerides and their degree of unsaturation. ISO/TS 17383:2014 is…

ISO 249:2014 specifies a method for the determination of the dirt content of raw natural rubber. It is not applicable to dirt present as surface contamination.

ISO 2469:2014 describes the general procedure for measuring the diffuse radiance factor of all types of pulp, paper and board. More particularly, it specifies in detail the characteristics of the equipment to be used for such measurements, and the procedures to be used for calibrating that equipment. ISO 2469:2014 may be used to measure the diffuse radiance factors and related properties of…

ISO 14388-3:2014 specifies a suite of methods used to determine net acidity in acid sulfate soils. ISO 14388-3:2014 specifies a method for the determination of pH in a 1 mol/l potassium chloride soil suspension (pHKCl) and where required, titratable actual acidity (TAA). Following this, potassium chloride extractable sulfur (SKCl), calcium (CaKCl) and magnesium (MgKCl) are determined. On a…

ISO 18068:2014 specifies a test method to determine the total sugar content in cotton fibres. Spectrophotometry is used as a quantitative determination method, and 3,5-dihydroxytoluene-sulfuric acid solution is used as a colour developer. ISO 18068:2014 is applicable to cotton fibres.

ISO Guide 80 outlines the essential characteristics of reference materials for quality control (QC) purposes, and describes the processes by which they can be prepared by competent staff within the facility in which they will be used (i.e. where instability due to transportation conditions is avoided). The content of this Guide also applies to inherently stable materials, which can be transported…

ISO 6101-3:2014 specifies an atomic absorption spectrometric method for the determination of the copper content of rubbers. The method is applicable to raw rubber and rubber products having copper contents above 1 ppm. Copper contents below this limit can be determined, provided that suitable adjustments are made to the mass of the test portion and/or to the concentrations of the solutions used.…

ISO 6101-4:2014 specifies an atomic absorption spectrometric method for the determination of the manganese content of rubbers. The method is applicable to raw rubber and rubber products having manganese content above 0,5 ppm. Manganese contents below this limit can be determined, provided that suitable adjustments are made to the mass of the test portion and/or to the concentrations of the…

IEC 60079-2:2014 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60079-2:2014 contains the specific requirements for the construction and testing of electrical equipment with…

IEC 60079-2:2014 contains the specific requirements for the construction and testing of electrical equipment with pressurized enclosures, of type of protection "p", intended for use in explosive gas atmospheres or explosive dust atmospheres. It also includes the requirements for pressurized enclosures containing a limited release of a flammable substance. This standard supplements and…
