This document specifies a procedure for carrying out impressed current electrochemical chloride extraction from chloride bearing concrete in existing structures. It is applicable to atmospherically exposed parts of structures with ordinary reinforcement and/or post-tensioned tendon ducts embedded in concrete. In the latter case, it is essential to verify that there is no risk of hydrogen embrittlement, if necessary by conducting trials and installing monitoring during the treatment. This document does not apply to concrete containing pre-stressing steel which can suffer hydrogen embrittlement during chloride extraction, or to concrete containing epoxy-coated or galvanized reinforcement. In case of post-tensioned, pre-stressing concrete, the endangered tendon strands may be shielded by the tendon ducts from unwanted and/ or exceeded polarization into the cathodic range and respective water reduction.

1.1 This document is applicable to simple unfired steel pressure vessels, referred to as “vessel” in this document, designed for air braking equipment and auxiliary pneumatic equipment for railway rolling stock (see Clause 13). It defines three types of vessel A, B and C (see Table 1) corresponding to the current practice of European railway networks. 1.2 The vessels in this document are: a) made from a single shell; b) made from non-alloy steel; c) fabricated by welding; d) used at a maximum working pressure of 15 bar; e) the product of the maximum working pressure (in bar) and the volume (in litre): 50 bar litres < PV ≤ 10 000 bar litres; f) made of a cylindrical part of circular cross-section called the shell with two outwardly dished torispherical ends, that is two dished ends with the same axis of rotation. This document therefore does not apply to vessels with one or two flat ends or those made up of several compartments; g) calculated with a design pressure P (see 5.1.4.1.2); h) designed for a working temperature of between −40 °C and +100 °C; i) fastened to vehicles: 1) by straps for types A and B vessels, 2) by welded brackets for types B and C vessels. 1.3 In normal service, a momentary overpressure of 10 % of PS, the maximum working pressure PS, is permitted. 1.4 This document applies to the vessel proper, from the inlet connection to the outlet connection and to all other connections and fittings belonging to the vessel. 1.5 This document gives the requirements to be met for the calculation, design, fabrication, inspection during fabrication and certification of the vessel, and fittings for assembly to the vehicle. These requirements cannot be written in sufficient detail to ensure good workmanship or proper construction. Each manufacturer is therefore responsible for taking every necessary step to make sure that the quality of workmanship and construction is such as to ensure compliance with good engineering practice. This document gives: a) in Annex B, recommendations for assembly to the vehicles; b) in Annex C, recommendations for the service surveillance of type A vessels; c) in Annex D, recommendations for the service surveillance of types B and C vessels. The requirements of this document apply to vessels designed to be fitted to rail vehicles.

This European Standard specifies the minimum requirements for visors designed specifically to be used only with protective helmets, including but not limited to those conforming to EN 443, EN 14052, EN 16471 and EN 16473 as the situation dictates. These visors may be permanently fitted to, or removable from, the helmet. See the scope of the various helmet standards for applications. These visors are not intended to protect against smoke and gas /vapour hazards. Three types of visors in two forms are described in this document. The two forms are: - face guards provide both eye and face protection, and - eye guards that are shorter and effectively provide only eye protection. The three types are: - Visors for general use: Eye guards and face guards providing resistance and/or protection against mechanical, liquid chemical and basic physical hazards. - Visors with increased thermal performance: Face guards that additionally provide resistance and/or protection against higher than basic levels of heat and flame. This additional requirement is not applicable for eye guards. - Mesh visors: Eye guards and face guards that incorporate mesh oculars with defined levels of performance from EN 1731, and other additional mechanical requirements described in this standard. Visors for sporting use, those with corrective effect, and goggles used with a protective helmet are not covered by this standard.

This document provides principles and requirements for the assessment of environmental, social and economic performance of buildings and civil engineering works taking into account their technical characteristics and functionality. Assessments of environmental, social and economic performance are the three aspects of sustainability assessment of buildings and civil engineering works, or combination thereof, (hereafter referred to as “construction works”). The framework applies to all types of construction works, both new and existing, and it is relevant for the assessment of the environmental, social and economic performance of new construction works over their entire life cycle, and of existing construction works over their remaining service life and end of life stage. The sustainability assessment of construction works concentrates on the assessment of environmental, social and economic aspects and impacts of construction works expressed with quantifiable indicators. It includes the assessment of a construction works’ influence on the environmental, social and economic aspects and impacts on the local area (area of influence) and of the local infrastructure beyond the curtilage of the building and the civil engineering works. It excludes environmental, social and economic risk assessment. The European Standards developed under this framework do not set the rules for how the different assessment methodologies may provide valuation methods; nor do they prescribe levels orclasses for measuring performance. NOTE Valuation methods, levels, classes or benchmarks can be prescribed in the requirements for environmental, social and economic performance in the client’s brief, construction regulations, national standards, national codes of practice, construction works assessment and certification schemes, etc. The rules for assessment of environmental, social and economic aspects of organizations, such as management systems, are not included within this framework. However, the consequences of decisions or actions that influence the environmental, social and economic performance of the object of assessment are taken into account.
