Building intercom systems - Application guidelines. General1 Scope This part of IEC 62820 series gives guidelines for planning, installation, commissioning, operation and maintenance of Building Intercom Systems (BIS), for use in security applications. The different technical requirements for BIS are specified in IEC 6282011 and IEC 6282012. The objectives of this document are to: a) provide a framework to assist system integrators, installers, consultant engineers and system owners in establishing their

are within the scope of BS EN 55014-2

It is applicable to reciprocating internal combustion engines (spark-ignition or compression-ignition) — excluding free-piston engines — and rotary piston engines

BS EN 61249-2-42 is the second part of a multi-series standard used for Materials for printed boards and other interconnecting structures

and optical performance

The sensitivity obtained using this part of the ISO 16063 standard for accelerometers with a DC response can be used over the flat part of the low-frequency range of the accelerometer

BS 3680-4F deals with the measurement of flow in rivers and artificial channels under steady flow conditions using round-nose horizontal broad-crested weirs

It is a type-test procedure for establishing the magnitude of vibration in the gripping areas of a machine fitted with an inserted tool bit

• Tolerance to impulse interference

It does not constitute a complete description of these controls nor does it attempt to standardize them

Technical delivery conditions for sheet/plate and strip of corrosion resisting steels for construction purposes

It is not applicable to special radiographic applications such as mammography
