This document specifies the requirements for rubber hoses and hose assemblies, up to a maximum hose size of 19, for use in motor vehicles with liquefied petroleum gas (LPG) installations. The hoses are designed for use up to a maximum working pressure of 3,0 MPa (30 bar) and at working temperatures from −40 °C up to and including +80 °C.

This International Standard specifies the endurance test necessary to confirm the ability of hand-operated plastics valves to withstand prolonged use, with repeated opening and closure. It does not specify the ability of valves to withstand adverse conditions, in particular those of chemically aggressive fluid media and/or environments, or excessive fluid velocities and cavitation.

NOTE For what concern the chemical aggression of the materials, a classification table is reported in ISO TR 10358[1].

This International Standard includes values of the parameters necessary for the proper performance of the endurance test, with the reservation that parameters may be different in particular product standards (see 5.1).

unplasticized poly(vinyl chloride) (PVC-U) profiles with light coloured surfaces intended to be used for the fabrication of windows and doors.

It is applicable to PVC-U profiles with the colorimetric co-ordinates measured on the visible surfaces, as follows:

L* ≥ 82 (chromaticity co-ordinate Y ≥ 60),

— –2,5 ≤ a* ≤ 5,

— –5 ≤ b* ≤ 15.

NOTE 1 For editorial reasons in this document the term "window" is used for window/door.

NOTE 2 Profiles made from PVC-U materials with reinforcements (e.g. glass fibres) are not part of this scope.

This document specifies the types and proportions of raw materials to be used for wood-plastic recycled composites (hereafter referred to as WPRC). It also specifies the health and safety requirements for WPRC and the methods to test these properties.

This document is applicable to WPRC which are primarily used as building materials.
