This document specifies the technical delivery conditions for qualities TR1 and TR2 of electric welded and submerged arc welded tubes of circular cross section, with specified room temperature properties, made from non-alloy quality steel. NOTE 1 Quality TR2 is intended to support the essential requirements of EU Directive 2014/68/EU in respect of pressure equipment with specified room temperature properties (see Table 5). NOTE 2 Once this standard is published in the Official Journal of the European Union (OJEU), presumption of conformity to the Essential Safety Requirements (ESR) of Directive 2014/68/EU is limited to the technical data for the materials in this standard and does not presume adequacy of the material for a specific item of pressure equipment. Consequently, the assessment of the technical data stated in this material standard against the design requirements of a specific item of equipment to verify that the ESRs of the Pressure Equipment Directive are satisfied, needs to be done by the designer or manufacturer of the pressure equipment, taking also into account any subsequent processing procedures which may affect properties of the base materials.

This document specifies a method for determining the long-term sealing pressure of elastomeric seals in assembled joints for buried non-pressure sewerage plastics piping and ducting systems.

This document specifies the requirements for three types, three classes and two categories of textilereinforced rubber hose for compressed air, up to a maximum working pressure of 2,5 MPa (25 bar) with an operating-temperature range of −40 °C to +70 °C, depending on the type and category.

This document specifies the requirements for flexible thermoplastic polyurethane and polyamide tubing conveying compressed air, in sizes from 3 mm to 16 mm for metric sizes and from 1/8’ to 1/2' for inch size outside diameter.
Polyurethane tubing are dedicated for use in the temperature range from – 20 °C to 60 °C, while polyamide tubing from – 20 °C to 80 °C. Working pressure depends on the tube size, the service temperature (see Tables 13 and 14) and tubing material (see Tables 15 and 16).

This document specifies the requirements, sampling, test methods and conditions of delivery for seamless round copper tubes, smooth or inner finned, used for heat exchangers and their internal connecting pipes in the manufacturing of refrigeration and air conditioning equipment.
It is applicable to tubes with an outside diameter from 3,97 mm up to and including 219 mm.
NOTE The tubes are supplied in straight length or as coils.
