This document describes procedures for factory production control, third party inspection, and certification for verifying the conformity of gully tops and manhole tops with a clear opening up to and including 1 000 mm for installation within areas subjected to pedestrian and/or vehicular traffic in accordance with prEN 124-7. This document is only applicable in combination with prEN 124-7. The quality management system is expected to conform to or to be no less stringent than the relevant requirements of EN ISO 9001. This document details the applicable characteristics to be assessed for type testing, batch release test, process verification test and audit test, as well as frequency and sampling for testing products according to prEN 124-7.

This document describes two test methods: - basket method (see Clause 4); - beaker method (see Clause 5). The basket method describes a method for determining binder drainage of bituminous mixtures. This method directly measures binder drainage, but when carried out on bituminous mixtures with fibres or mixtures whose mortar content is higher than in porous asphalt some clogging of the holes in the drainage baskets can occur, limiting the drainage of the binder. The basket method can be used either for determining the binder drainage for different binder content, or with a single binder content, eliminating the successive repetitions. It also enables the effects of varying fine aggregate types or including any anti-draining additive to be quantified. The beaker method describes a method for determining binder drainage of bituminous mixtures. It is applicable to asphalt materials that are not porous asphalt or for porous asphalt incorporating fibres. It can be used either for determining the binder drainage for different binder content, or with a single binder content, eliminating the successive repetitions. It also enables the effects of varying fine aggregate types or including any anti-draining additive to be quantified.

This document applies to a) manholes, when made from glass-reinforced thermosetting plastics (GRP) based on polyester resin (UP); b) inspection chambers, when made from glass-reinforced thermosetting plastics (GRP) based on polyester resin (UP) which are intended to be used with inverts which are at a depth not exceeding 2 m. These products are intended to be used within a drain or sewer system operating without pressure or occasionally at a head of pressure up to 1 bar. It applies to products, and their joints, intended for use in buried installations and to be installed by open-trench techniques. The units have a circular shape with nominal sizes as specified in EN ISO 23856. The intended use of these products is to provide access to, buried drain or sewer systems for the conveyance of waste water at temperatures up to 50 °C, without pressure or occasionally at a head of pressure up to 1 bar, outside buildings and installed in areas subjected to vehicle and/or pedestrian traffic. It specifies definitions including symbols, requirements and characteristics of manholes, inspection chambers, joints, materials, test methods and marking. NOTE It is the responsibility of the purchaser or specifier to make the appropriate selections, taking into account their particular requirements and any relevant national regulations and installation practices or codes.

This document applies to gully tops and manhole tops with a clear opening up to and including 1 000 mm for installation within areas subjected to pedestrian and/or vehicular traffic. It applies for manhole tops and gully tops of classes A 15 to D 400 made from polyamide (PA 6 and PA 6.6) by casting or injection-moulding. This document is only applicable in combination with EN 124-1 and prEN 124-700. This document does not apply - for fillings installed on site, e.g. concrete, paving blocks etc., - for gratings as part of prefabricated drainage channels according to EN 1433, - to floor and roof gullies in buildings which are specified in EN 1253 (all parts) and to surface boxes.

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.
