This European Standard specifies requirements and test methods for straight lengths of factory made thermally insulated bonded single pipe assemblies for hot water networks in accordance with prEN 13941-1:2016, comprising a steel service pipe, rigid polyurethane foam insulation and a casing of polyethylene.

The pipe assembly may also include the following additional elements: measuring wires, spacers and diffusion barriers.

This document specifies the requirements for solid wall pipes with smooth internal and external surfaces, extruded from the same formulation throughout the wall, fittings and the system of unplasticized poly(vinyl chloride) (PVC-U) piping systems in the field of non-pressure underground drainage and sewerage:

— buried in ground outside the building structure (application area code "U"), and

— both buried in ground, within the building structure (application area code "D") and outside the building.

This is reflected in the marking of products by "U" and "UD".

It also specifies the test parameters for the test methods referred to in this document.

NOTE 1 Solid wall multilayer pipes with different formulations throughout the wall and foamed core pipes are covered by EN 13476-2 [1] (see also CEN ISO/TR 27165 [2]).

This document covers a range of nominal sizes, a range of pipes and fittings series and a range of stiffness classes and gives recommendations concerning colours.

NOTE 2 It is the responsibility of the purchaser or specifier to make the appropriate selection from these aspects, taking into account their particular requirements and any relevant national regulations and installation practices or codes.

In conjunction with prCEN/TS 1401-2 [3], it is applicable to PVC-U pipes and fittings, their joints and to joints with components of other plastics and non-plastics materials intended to be used for buried piping systems for non-pressure underground drainage and sewerage.

NOTE 3 Pipes, fittings and other components conforming to any of the plastics product standards listed in Annex C can be used with pipes and fittings conforming to this document, provided they conform to the requirements for joint dimensions given in Clause 7 and to the requirements of Table 15.

This part of ISO 9809 specifies minimum requirements for the material, design, construction and workmanship, manufacturing processes, examination and testing at time of manufacture for

- refillable seamless steel gas cylinders and tubes

- of water capacities up to and including 450 l

- for compressed, liquefied and dissolved gases.

- quenched and tempered steel cylinders and tubes with an actual tensile strength Rma ≥ 1 100 MPa.

It is not applicable to:

- cylinders and tubes with Rma, max > 1 300 MPa for diameters > 140 mm and guaranteed wall thicknesses a′ ≥12 mm and

- cylinders and tubes with Rma, max > 1 400 MPa for diameters ≤140 mm and guaranteed wall thicknesses a′ ≥6 mm,

because beyond these limits, additional requirements can apply.

This document specifies tests, procedures and a method of presenting the results concerning the parameters that define the main characteristics to be included in the supplier’s literature of lubricators conforming to ISO 6301-1.

This document can be applied:

— to facilitate the comparison of lubricators by standardizing test methods and presentation of test data;

— to assist in the proper application of lubricators in compressed-air systems.

The tests specified are intended to allow comparison between the different types of lubricators; they are not production tests to be carried out on each lubricator manufactured.
