This document specifies restoration by electric arc welding and is limited to the head of the rails only. This document describes the approval systems for consumables and procedures used in manual metal arc and flux cored metal deposit rail repair welding. This document includes the quality-related tasks and responsibilities of personnel involved in the electric arc repair welding of rails. This document applies to plain rail and switches and crossings manufactured from new Vignole railway rails R200, R220, R260, R260Mn, and R350HT grades rails of 27 kg/m and above as contained in EN 13674-1, EN 13674-2 and EN 13674-4. The permitted welding processes are limited to Electric Arc (EA) in accordance with EN ISO 4063 and are by description Process No 111: SMAW (Shielded Metal Arc Welding) and Process No 114: FCAW (Flux Cored Arc Welding). This document can be applied in situ, at line side or at out of track locations. The flash welded leg ends of austenitic manganese steel crossings are included in this document, except when located within 500 mm of manganese crossings. Where repairs are required within 500 mm, refer to EN 16725.

This document specifies a test method for determining the particle loss of porous asphalt mixtures. Particle loss is assessed by the loss of mass of porous asphalt samples after turns in the Los Angeles machine. This test enables the estimation of the abrasion resistance of porous asphalt. The test applies to laboratory compacted cylindrical specimens of porous asphalt mixtures, the upper sieve size of which does not exceed 22,4 mm. It does not reflect the abrasive effect by studded tyres.

This document specifies a test method for determining the (splitting) indirect tensile strength of cylindrical specimens of bituminous mixtures.

This document specifies test methods for sampling bituminous mixtures for roads and other paved areas to determine their physical properties and composition.

This document establishes the specifications for the execution of tension tests to be carried out on soil nails and rock bolts. NOTE 1 Soils nails and rock bolts are referred as elements in the scope of this document.

NOTE 2 This document covers but is not limited to grouted soil nails and rock bolts.

NOTE 3 This document does not provide specification for the number of tests, the type of test, the Test Method, the value of the proof load and the limiting criteria. These aspects reside in EN 1997-3 or its national annex for CEN countries and in similar national application documents for ISO countries.

This document provides specifications for three types of tension tests: investigation tests, suitability tests and acceptance tests.

Two methods of testing are recognised by this document. Test Method A involves step-loaded maintained load tension tests. Test Method B involves constant displacement rate tension tests.

This document provides specifications for the experimental devices, the measurement apparatus, the test procedures, the definition and the presentation of the test results and the content of records, aiming at:

a) measuring the pull-out resistance of a soil nail or a rock bolt,

NOTE 4 A loading test performed using this standard provides the pulled-out resistance along the bonded length, that might differ from the pull-out resistance considered in design.

b) checking that a soil nail or rock bolt behaves as designed.

This document specifies the definitions and requirements for solid-wall pipes with or without internal skin and smooth internal and external surfaces extruded from the same compound throughout the wall, fittings and the system of polyethylene (PE) piping systems to be intended for use in non-pressure underground drains and sewers for foul wastewater.

NOTE 1 Products complying with this document can also be used in non-pressure underground drains and sewers for surface water.

This document is applicable to:

a) non-pressure drains and sewers, which are intended to be used buried underground outside the building structure; reflected in the marking of products by “U”;

b) non-pressure drains and sewers, which are intended to be used buried underground both outside (application area code “U”) and within the building structure, reflected in the marking of products by “UD”.

This document specifies test methods referred to in this document and test parameters.

This document is applicable to pipes and fittings with or without an integral socket.

This document covers a range of pipe and fitting sizes, stiffness classes, tolerance classes and gives recommendations concerning colours.

NOTE 2 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 regulations and installation practices or codes.

In conjunction with CEN/TS 12666-2 [1] it is applicable to PE 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 drains an sewers.

The fittings can be manufactured by injection moulding or can be fabricated from pipes and/or mouldings.

This document is applicable to PE pipes and fittings for the following types of joints:

— elastomeric ring seal joints;

— butt fused joints;

— electrofusion joints;

— mechanical joints.

NOTE 3 Pipes, fittings and other components conforming to any of the plastics product standards listed in the Annex D (informative) 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 Clause 7 and Table 13.
