Liquid petroleum products — Determination of hydrocarbon types and oxygenates in automotive-motor ga...
ISO 22854:2014 specifies the gas chromatographic (GC) method for the determination of saturated, olefinic and aromatic hydrocarbons in automotive motor gasoline and automotive ethanol fuel (E85). Additionally, the benzene content, oxygenate compounds and the total oxygen content can be determined.
This International Standard defines two procedures, A and B.
Procedure A is applicable to automotive…
Safety of Products and Materials in Contact with Drinking Water
SCOPE
This standard applies to all types of materials (for example, plastics, other polymers, metal, cement)
and products (for example, pipes, gaskets, valves, coating materials, lubricants) in contact with
drinking water in a temporary or permanent cold drinking water supply system.
NOTES —
1 Fire hydrants fall within the scope of this standard since they are major elements of a temporary…
ISO 2476:2014 specifies:
- physical and chemical tests on raw rubbers;
- standard materials, standard test formulations, equipment, and processing methods for evaluating the vulcanization characteristics of solution-polymerized butadiene rubbers (BR), including oil-extended types (OEBR), and the tensile stress-strain properties of vulcanized mixes.
Specifications for particular types of winding wires - Part 52: Aromatic polyamide (aramid) tape wra...
IEC 60317-52:2014 specifies requirements for tape wrapped round copper winding wire of temperature index 220. The insulation consists of one or more wrappings of aromatic polyamide (aramid) tape of various thicknesses. The range of nominal conductor diameters covered by this standard is:
- 1,600 mm up to and including 5,000 mm;
- the nominal conductor diameters are given in Table 1. This second…
Information technology - Environmental Data Coding Specification (EDCS)
ISO/IEC 18025:2014 provides mechanisms to specify unambiguously objects used to model environmental concepts. To accomplish this, a collection of nine EDCS dictionaries of environmental concepts are specified:
classifications: specify the type of environmental objects;
attributes: specify the state of environmental objects;
attribute value characteristics: specify information concerning the…

IEC 60317-51:2014 specifies the requirements of solderable enamelled round copper winding wire of class 180 with a sole coating based on polyurethane resin, which may be modified providing it retains the chemical identity of the original resin and meets all specified wire requirements. The range of nominal conductor diameters covered by this standard is as follows:
- Grade 1: 0,018 mm up to and…
ISO 2322:2014 specifies:
- physical and chemical tests on raw rubbers;
- standard materials, standard test formulations, equipment, and processing methods for evaluating the vulcanization characteristics of emulsion- and solution-polymerized styrene-butadiene rubbers (SBR), including oil-extended rubbers.
Shunt power capacitors of the self-healing type for a.c. systems having a rated voltage up to and in...
IEC 60831-1:2014 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 60831-1:2014 is applicable to both capacitor units and capacitor banks intended to be used, particularly, for power…
IEC 61754-30:2014 defines the standard interface dimensions for the type CLIK series of connectors. Keywords: interface dimensions, type CLIK, connectors
