British Standards control

Instrument Society of America 400 Stanwix Street Pittsburgh, Pa. 15222 Standards l ibrary for Measurement and Control, 12th ed., 1994. Instmmentation standards and recommended practices abstracted from those of 19 societies, the U.S. Government, the Canadian Standards Association, and the British Standards Institute. Covers control instmments, including rotameters, aimunciators, transducers, thermocouples, flow meters, and pneumatic systems (see... 

Flammable liquids are considered particularly static-prone if their elec trical conductivity is within the range of 0.1 to 10 pS/m. If no particulates or immiscible liquid are present, these prodlic ts are considered safe when their conductivity has been raised to 50 pS/m or higher. Blending operations or other two-phase mixing may cause such a high rate of charging that a conductivity of at least 1000 pS/m is needed for safe charge dissipation (British Standard 5958, part 1, Control of Undesirable Static Electricity, para. 8, 1991). 

There are three standards controlling surface finish in common use. They are issued by the Steel Structures Painting Council (USA), the Swedish Standards Organisation and the British Standards Institution. They are roughly equivalent. 

Other notaries are the Consensus on Operating Practices for the Control of Feedwater and Boiler Water Chemistry in Modem Industrial Boilers (1994 edition), published by the American Society of Mechanical Engineers, and BS 2486 1997 Recommendations for Treatment of Water for Steam Boilers and Water Heaters from the British Standards Institution. The 1994 Consensus (with its engineering background) and the 1997 version of BS 2486 (with its strength in operational chemistry) complement each other well. I consider that the tables and propositions contained in these two booklets jointly represent a true standard for boiler water treatment operational control. Consequently, I am pleased to be able to reproduce in this book all the tables from both publications, having received permission from the respective organizations to do so. 

Standard symbols for instruments, controllers and valves are given in the British Standard BS 1646.

A welcome addition to the controls imposed by the HSE which relate to the manufacture, keeping, safe conveyance and importation of explosives, including fireworks, is the British Standard BS7114. This standard applies specifically to consumer fireworks and was promulgated in 1988 in order to deal with aspects such as the categorisation, performance testing, quality control and labelling of all types of fireworks. 

Part 2 of the British Standard lists all of the main types of firework within Category 1, Category 2 and Category 3, and provides specification requirements by which the construction and performance of these fireworks can be controlled. Aspects that are addressed include means of ignition, projection of burning matter, projection of debris, principal pyrotechnic effects and the angle of flight of rockets.

A British Standard has been published to assist with the management of waste systems, BS 7750. This standard is linked to the standard on management for quality control, BS 5750. 

Indebtedness is expressed to Prof. R. A. Fisher and Dr. Frank A. Yates for permission to reprint Tables III-VI from their book Statistical Tables for Biological, Agricultural, and Medical Research (Oliver Boyd, Edinburgh and London), and to the British Standards Institution for permission to reprint certain factors for Quality Control Charts from B.S, 600R, Quality Control Charts. ... 

The literature of industrial quality control is now very great. The standard work is W. A.. Shewhart s Economic Control of Quality of Manufactured Product (Macmillan r 1931). Short accounts are British Standard 600R Qualitj Control Charts, B. P. Dudding and W. J. Jennett, 1942 British Standard 1008 Quality Control A First Guide to Quality Control for F-ngineers, E. H. Sealy, H.M.S.O., 1946. A fuller account is L. E. Simon s An Engineer s Manual of Statistical Methods (Chapman Hall, 1941).

Passive sampling protocols were based on BSI PAS-61 (British Standards Institute, 2006), and triplicate field blanks were used to assess possible contamination during manufacture, deployment, retrieval and transport. In field trials it is not possible to produce controlled fluctuations in concentrations of pollutants, but by chance in this work concentrations of most metals were higher during the first 14 days of the 28 day trial and two peaks of concentration of were observed in the frequent spot samples...
