Railway applications. Track. Acceptance of works - Works on ballasted track. Plain line, switches and crossings Ingestion-build-63436 test methods and marking requirements

test methods and marking requirements for half masks (re-usable) without inhalation valves and with separable filters (designed for a maximum of single shift use) to protect against gases or gases and particles or particles only

This streamlines the design while also providing rigorous systems that prevent stressors

but it is recognized that bolts and nuts of these dimensions may be required with a higher grade of finish for certain applications

Railway applications. Track. Acceptance of works - Works on ballasted track. Plain line, switches and crossings Ingestion-build-63436 test methods and marking requirements1 Scope This European Standard specifies the minimum technical requirements and the tolerances for the acceptance of works on ballasted track situated on plain line and on switches and crossings and rail expansion devices, as part of the track, for 1 435 mm and wider track gauge railways, concerning construction of new track, track renewal and track maintenance. More particularly, this standard gives the requirements for the documentation of work
