Electrical relays. Vibration, shock, bump and seismic tests on measuring relays and protection equipment - Shock and bump tests1 Scope This standard is part of a series specifying the vibration, shock, bump and seismic requirements applicable to electromechanical and static measuring relays and protection equipment with or without output contacts. This standard includes two types of test: the shock test (on energized and non energized specimen); the bump test (on non energized specimen), and is generally based on IEC 68227 and IEC 68229. The requirements of this standard are

construction and performance of domestic external composite doorsets

Symbols SE for shielding effectiveness and ZT for surface transfer impedance added throughout the document

Amendment 1 introduces the following principal changes:

the optical output power is limited to a predetermined level (Pout-limit)

All the requirements of ISO 15378 are generic and are intended to apply to any organization

BS 6829 discusses the analysis of surface-active agents

Classes of appliances

selling and using black hexagon bolts

not specified in this standard

BS EN 17199-5 lets manufacturers that use NOAA materials
