This document specifies methods for determining the change of appearance and stability of a textile floor coverings or any damage caused by detachment of layers, opening of joints, cracks, or crazing of a resilient, laminate or modular mechanical locked floor coverings under the movement of a swivel castor chair.

 

This document specifies the properties of the piping system and its components made from glass-reinforced thermosetting plastics (GRP) based on unsaturated polyester (UP) resin. It is suited for all types of water supply, drainage and sewerage with or without pressure. Types of water supply include, but are not limited to, raw water, irrigation, cooling water, potable water, salt water, sea water, penstocks in power plants, processing plants and other water-based applications. This document is applicable to GRP-UP piping systems, with flexible joints, intended to be installed using jacking techniques. It specifies the characteristics of pipes made from GRP-UP, with or without aggregates or fillers. It also specifies the test parameters for the test methods referred to in this document. This document is applicable to circular pipes and joints with a size range from DN 100 to DN 4 000 at normal service conditions. This document covers requirements to demonstrate the adequacy of the design of the joint and specifies type test performance requirements for the joints as a function of the declared nominal pressure rating of the pipeline system and the required joint deflection capability of the system. The determination of longitudinal compressive properties of a pipe are given in Annex A and Annex B. The procedure for the calculation of the design jacking load on a GRP (UP) pipe is given in Annex C. Requirements for GRP-fittings, used between pipe systems covered by this document, are given in ISO 23856.

 

This document specifies the test method for testing the axial coefficient of linear expansion of straight plastic pipes by using the push-rod differential method. Plastic pipes include pure plastic pipes, fiber reinforced pipes and metal reinforced pipes, etc. The test temperature range specified in this document is 20 °C to 95 °C. This document does not apply to plastic pipes with axial expansion coefficient less than 1×10-6 /°C.

 

This document specifies requirements and test methods for joint casing systems for single and twin pipes between adjacent factory-made pipe, and/or fitting and/or valve assemblies for buried heating and cooling water networks with rigid pipe systems with metal service pipes in accordance with EN 13941-1 [4] and EN 13941-2 [5] as well as rigid pipe systems with plastic service pipes according to series EN 17415 and flexible pipe systems with metal service pipes according to EN 15632-4 . NOTE There are no differences in requirements for single and twin pipe joint casing systems. For bedding materials other than those defined in 5.2.3 additional precautions are defined inEN 13941-2 [5].

 

This document gives guidance and requirements for the assessment of conformity of compounds, products, joints and assemblies in accordance with the applicable part(s) of EN 1555, intended to be included in the manufacturer’s quality plan as part of the quality management system and for the establishment of certification procedures. NOTE 1 A test matrix provides an overview of the testing scheme in Annex B, Table B.1. NOTE 2 If certification is involved, the certification bodies and inspection bodies operating in accordance with EN ISO/IEC 17065 [2] and EN ISO/IEC 17020 [4] are considered to be competent. Mechanical fittings according to ISO 17885 are not covered in this document. In conjunction with EN 1555-1, EN 1555-2, EN 1555-3, EN 1555-4 and EN 1555-5, this document is applicable to PE pipes, fittings, and valves, their joints and joints with components of PE and other materials intended to be used under the following conditions: a) a maximum operating pressure, MOP, up to and including 10 bar , at a design reference temperature of 20 °C; b) an operating temperature between -20 °C and 40 °C. For operating temperatures between 20 °C and 40 °C, derating coefficients are specified in EN 1555 5. The EN 1555 series covers a range of MOPs and gives requirements concerning colours. It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national guidance or regulations and installation practices or codes.
