This International Standard specifies test methods for adhesives for bonding parquet and similar wood floorings to a subfloor. It also specifies the minimum requirements for shear strength, tensile strength to be achieved with these adhesives.

This International Standard does not refer to the selection and installation of parquet floorings.

This document provides specification and testing requirements for high pressure flexible hose assemblies intended to be connected to gas cylinders, bundles of cylinders or trailers (battery vehicles), and MEGCs for use when filling and emptying gas at production sites and also for customer use. This document applies to flexible hose assemblies with rated pressures up to 1 000 bar for use in the temperature range of −40 °C to +65 °C.

This document is not applicable to:

— rubber and plastics flexible hose assemblies for welding, cutting and related processes up to 45 MPa (450 bar) for customer use (see ISO 14113);

— high pressure flexible hose assemblies for use with medical gas systems for customer use (see ISO 21969);

— low pressure hose assemblies for use with medical gases for customer use (see ISO 5359);

— rubber and thermoplastic low pressure hose assemblies for welding, cutting and related processes for customer use (see ISO 3821 or ISO 12170);

— flexible hose assemblies for cryogenic applications (see ISO 21012);

— flexible hose assemblies for liquid petroleum gas (LPG).

NOTE Flexible hose assembly designs which pass the type test approval described in this document can have a lower ratio of burst pressure to rated pressure than stated in other standards.

This document defines the general terms and basic requests for adhesive bonding and sealing work as well as the requirements placed on adhesive users (hereafter called user-companies) and represents the state of the art for organizing adhesive bonding and sealing processes in the railway industry.

This document applies for adhesive bonding and sealing adherends for:

— the development of rail vehicles and its components (pre-production),

— production of rail vehicles and its components (in-production),

— the maintenance incl. repair of rail vehicles and its components (post-production), and

— the quality assurance of production, inspection, maintenance incl. repair of rail vehicles and its components.

This document is valid for every adhesively bonded joint in railway vehicles and its components independent of the material of the adherend. It is also valid for all kinds of adhesives independent of their solidification mechanism, their strength and their deformation properties.

This document is not valid for:

— screw retention by the usage of adhesives, if a pure screw assembly of the same design is sufficient for the purpose,

— hybrid joints, if the expected function is given exclusively by another joining technology e.g. welding, screwing, riveting,

— production of vulcanizates which do not lead to adhesively bonded joints,

— production of plywood,

— production of fibre reinforced plastic composites (FRP-composites),

— production of laminated sheet glass (LSG),

— pure encapsulating of electronic parts, and

— single-sided adhesive decorative films.

This document establishes a method for determination of the thermal conductivity of solid unfilled and filled or fibre reinforced plastics and composites by means of Differential Scanning Calorimetry (DSC).

It is applicable for materials with thermal conductivities of up to 1 W/(m⋅K).
