This document defines the rules to be applied for symbolic representation of welded joints on technical drawings. This can include information about the geometry, manufacture, quality and testing of the welds. The principles of this document can also be applied to soldered and brazed joints.
It is recognized that there are two different approaches in the global market to designate the arrow side and other side on drawings. In this document:
— clauses, tables and figures which carry the suffix letter "A" are applicable only to the symbolic representation system based on a dual reference line;
— clauses, tables and figures which carry the suffix letter "B" are applicable only to the symbolic representation system based on a single reference line;
— clauses, tables and figures which do not have the suffix letter "A" or "B" are applicable to both systems.
The symbols shown in this document can be combined with other symbols used on technical drawings, for example to show surface finish requirements.
An alternative designation method is presented which can be used to represent welded joints on drawings by specifying essential design information such as weld dimensions, quality level, etc. The joint preparation and welding process(es) are then determined by the production unit in order to meet the specified requirements.
NOTE Examples given in this document, including dimensions, are illustrative only and are intended to demonstrate the proper application of principles.

This document specifies requirements for factory made thermally insulated bonded steel service valve assemblies for filling, draining, venting and operation purposes for directly buried hot and cold water networks in accordance with EN 13941-1, comprising a steel service valve, steel service pipe, polyurethane (PUR) foam thermal insulation and a casing of polyethylene (PE).
This document applies of steel service valve assemblies with an internal pressure of maximum 2,5 MPa.
The principles of this document can be applied to thermal insulated bonded steel service valve assemblies with internal pressures higher than 2,5 MPa, provided that special attention is paid to the effects of pressure.
The steel service valve assembly can also include the following additional elements: measuring wires, spacers, and diffusion barriers.

This document specifies requirements and test methods for fitting and steel valve assemblies of factory made thermally insulated bonded twin pipe assemblies for hot water networks in accordance with EN 13941-1, comprising two steel service pipes, in most cases steel fittings and/or steel valves, steel components, polyurethane (PUR) foam thermal insulation and one casing of polyethylene.
NOTE Steel components can be e.g. fixing bars.
The twin pipe assembly can also include the following additional elements: measuring wires, spacers and diffusion barriers.
This document covers the following assemblies:
- fittings: bends, T-pieces and reducers;
- valves for main line.
This document applies to fitting assemblies with an internal pressure of at least 1,6 MPa and steel valve assemblies with a maximum internal pressure of 2,5 MPa.

This document is applicable to the following groups of machines:
- powered hand strapping tools;
- semi-automatic strapping machines;
- automatic strapping machines.
This document does not apply to:
- strapping tools, where the strap tension is only applied by manual effort;
- machines, intended for use with paper strap;
- hand-held motor-operated electric strapping tools.
NOTE For hand-held motor-operated electric strapping tools see EN 60745-2-18:2009 and EN 62841-1:2015.
This document deals with safety requirements for machine design, transport, installation, commissioning, operation, adjustment, maintenance and cleaning. The extent to which hazards, hazardous situations and events are covered is indicated in Annex A.
This document does not consider the following hazards:
- the use of strapping machines in potentially explosive atmosphere;
- the health, safety or hygiene hazards associated with the products that may be handled by the machines, but does include general advice on this subject;
- hazards that are associated with decommissioning strapping machines.
Hazards associated with decommissioning of strapping machines are not considered and therefore excluded but are generally part of the instruction manual (see Clause 6), together with suited measures, if necessary.

This document specifies a procedure, at temperatures up to 100 °C, to determine whether a liquid product, that would be classified as “flammable” by virtue of its flash point, sustains combustion at the temperature(s) specified, for example, in regulations.
NOTE Many national and international regulations classify liquids as presenting a flammable hazard based on their flash point, as determined by a recognized method. Some of these regulations allow a derogation if the substance cannot “sustain combustion” at some specified temperature(s).
The procedure is applicable to paints (including water-borne paints), varnishes, paint binders, solvents, petroleum or related products and adhesives, that have a flash point. It is not applicable to painted surfaces in respect of assessing their potential fire hazards.
This test method is applicable, in addition to test methods for flash point, for assessing the fire hazard of a product.
