An escalator is a moving staircase that carries people between floors of a building or structure and moving walks is a slow-moving conveyor mechanism that transports people across a horizontal or inclined plane over a short to medium distance

b) Surface treated materials

BS 3984 specifies requirements for the following materials of technical quality:

BS EN 61158-6-18 provides common elements for basic time-critical and non-time-critical messaging communications between application programs in an automation environment and material specific to Type 18 fieldbus

Restrained joint systems for ductile iron pipelines. Design rules and type testing Ingestion-build-82396 you can identify the defects1 Scope This document specifies the design rules and type testing for restrained joint systems to be used on ductile iron pipelines complying with ISO 2531 and ISO 7186, in order to determine their mechanical properties and leaktightness.
