Bibliography

Provides recommendations for, and guidance on, the design for the installation of instrumentation of measurement and control systems in the process industry, and the implementation and commissioning of this installation.

This British Standard gives recommendations for, and guidance on, the design for the installation of instrumentation of measurement and control systems in the process industry, and the implementation and commissioning of this installation. It is intended to be used as a manual of good practice on the site and also to assist those who design the installation.

NOTE The recommendations given in this British Standard are based on the assumption that all instruments will have been specified and all instrument panels will have been designed.
