This document specifies the characteristics of hexagon thin nuts (style 0), in steel and stainless steel, with metric coarse pitch thread M1,6 to M64, and with product grades A and B.
Thin nuts used as jam nuts are to be assembled together with a regular or high nut.
WARNING — Thin nuts (style 0) have a reduced loadability compared to regular nuts or high nuts, and are not designed to provide…
This document specifies the characteristics of hexagon high nuts (style 2), in steel and stainless steel, with metric coarse pitch thread M5 to M39, and with product grades A and B.
If in certain cases other specifications are requested, property classes and stainless steel grades can be selected from ISO 898-2 or ISO 3506-2.
Fasteners — Hexagon high nuts (style 2), with fine pitch thread
This document specifies the characteristics of hexagon high nuts (style 2), in steel and stainless steel, with metric fine pitch thread 8 mm to 39 mm, and with product grades A and B.
If in certain cases other specifications are requested, property classes and stainless steel grades can be selected from ISO 898-2 or ISO 3506-2.
Analysis of natural gas — Biomethane — Determination of terpenes' content by micro gas chromato...
This document specifies a micro gas chromatography method for the on-line or offline determination of the content of five terpenes in biomethane, namely:
—    alpha-pinene,
—    beta-pinene,
—    para-cymene,
—    limonene,
—    3-carene.
The method is specifically developed for these five compounds. Information about the compounds is given in Annex A.
The method is applicable to the…
Plastics — Simple heat release test using a conical radiant heater and a thermopile detector
This document specifies a method suitable for the production control or product development purposes for assessing the heat release rate of essentially flat products exposed in the horizontal orientation to controlled levels of radiant heating with an external igniter. The heat release rate is determined by the use of a thermopile instead of the more accurate oxygen consumption techniques. The…
Road vehicles — Spark-plugs and their cylinder head housings — Basic characteristics and dimensions
This document specifies the main properties and dimensions of spark plugs, including the terminals and the dimensions of their cylinder head housings, for use with any spark-ignited engines. The usage of spark plugs is not restricted to road vehicles only.
This document does not cover screened and waterproof spark plugs (see ISOÂ 3412, ISOÂ 3895 and ISOÂ 3896).
Rubber seals — Joint rings for water supply, drainage and sewerage pipelines — Specification for mat...
This document specifies requirements for materials used in vulcanized rubber seals for the following:
a)      cold drinking-water supplies (up to 50 °C);
b)      drainage, sewerage, and rainwater systems (continuous flow up to 45 °C and intermittent flow up to 95 °C).
The different designations of seals specified are defined according to their type, application, and requirements (see Table 5).…
