IEC 60077-5:2019
Hind 151,26 EUR
Railway applications - Electric equipment for rolling stock - Part 5: Electrotechnical components - Rules for HV fuses
IEC 60077-5:2019 give additional or amended rules for high voltage (HV) fuses as a supplement to those given by IEC 60077-2. The high voltage fuses concerned are those connected into power and/or auxiliary circuits. The nominal voltage of these circuits lies between 600 V DC and 3 000 V DC, according to IEC 60850. These fuses can also be used in auxiliary AC circuits up to a nominal voltage of 1 500 V. This document together with IEC 60077-2 states specifically: a) the characteristics of the fuses; b) the service conditions with which the fuses comply with reference to: - operation and behaviour in normal service; - operation and behaviour in case of short circuit; - dielectric properties. c) the tests intended for confirming the compliance of the fuse with the characteristics under the service conditions and the methods adopted for these tests; d) the information marked on, or given with, the fuse. This second edition cancels and replaces the first edition, issued in 2003. This edition includes the following main technical changes with regard to the previous edition: a) test method of test duty III for verification of breaking capacity is reviewed.

IEC 60077-5:2019 RLV
Hind 196,64 EUR
Railway applications - Electric equipment for rolling stock - Part 5: Electrotechnical components - Rules for HV fuses
IEC 60077-5:2019 RLV contains both the official IEC International Standard and its Redline version. The Redline version is not an official document, it is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition.

Simple unfired pressure vessels designed to contain air or nitrogen - Part 4: Aluminium alloy pressure vessels designed for air braking equipment and auxiliary pneumatic equipment for railway rolling stock
1.1 This document is applicable to simple unfired aluminium alloy pressure vessels, referred to as "vessel" in this document, designed for air braking equipment and auxiliary pneumatic equipment for railway rolling stock (see 1.6). 1.2 The vessels to this document are: a) made from a single shell; b) made from aluminium alloy; c) fabricated by welding; d) used at a maximum working pressure of 10 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 5.1.4.2); h) designed for a working temperature of between −50 °C and +100 °C [+65 °C for certain grades of aluminium alloy (see 4.1.1)]; i) fastened to the vehicles by straps. 1.3 In normal service, a momentary overpressure of 1 bar of the maximum working pressure is permitted (10 % of PS). 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 vessels. 1.6 The requirements of this document apply to vessels designed to be fitted to rail vehicles used on the main national networks, urban networks, underground railways, trams, private networks (regional railways, company railways, etc.).

Railway applications - Wheelsets and bogies - Method of specifying the structural requirements of bogie frames
This document specifies the method to be followed to achieve a satisfactory design of bogie frames and includes design procedures, assessment methods, verification and manufacturing quality requirements. It is limited to the structural requirements of bogie frames including bolsters and axlebox housings. For the purpose of this document, these terms are taken to include all functional attachments, e.g. damper brackets.
