Highly rated boilers Various authorities [e.g., the British Standards Institute (BSI) and the American Society of Mechanical Engineers (ASME)] have differing views on what level of heat flux constitutes a highly rated boiler. However, from an operational... 

The British Standards Institute (BSI) is the independent national body responsible for preparing British Standards and presents the British view on many issues, including boiler water treatment practice. It is held in much the same level of esteem in Europe and the Commonwealth as ASME is in the United States.

For standardised instrumental analytical methods, i.e. biomarkers, biosensors and bioassays, there are well-established standard protocols on the national level, e.g. under Association Francaise de Normalisation (AFNOR), British Standard Institute (BSI), DIN (German Organisation for Standardisation), etc., and all those standards are formed by ISO-Working Groups and by validation studies into ISO - and CEN - Standards. Normal accredited and well-qualified laboratories should be able to perform the monitoring.

In a similar manner, the calibration of glassware, such as volumetric flasks, pipettes, burettes, measuring cylindres are duly carried out by specific methods recommended by Indian Standards Institution (ISI), British Standards Institution (BSI), National Physical Laboratory (NPL), United States Pharmacopoeia (USP) at specified temperatures (See Chapter 2). 

The British Standards Institution (BSI) has laid down the permitted tolerances and delivery times for commonly used bulb transfer pipettes as shown in Table 2.5. 

The British Standards Institution (BSI) and the National Physical Loaboratory (NPL) have laid down the tolerances in the capacity of volumetric flasks (i.e., measuring flask) at 20°C by two sets of tolerances viz., Grade A and Grade B respectively, evidently to indicate the class of accuracy to which the flask has been subjected to for graduation, followed by the manufacturer s name and finally the BS standard number. However, the permitted tolerances for volumetric flasks commonly used in analytical laboratories are depicted in Table 2.8. 

ISO standards were first published in 1972 before that time ISO recommendations was the title used. It is not obligatory for the ISO standards to be incorporated into a national system but obviously the whole aim is a little defeated if this is not done. The British Standards Institute (BSI) takes a very positive attitude in this direction following the dictum Do it once, do it right, do it internationally. Wherever possible, British standards are nowadays identical with ISO standards and have the same number (some older methods are still dual numbered). Furthermore, the standard is adopted and published nationally very rapidly without significant delay. This policy is followed by many other countries but, very significantly, not by the USA. 

The operations of the British Standards Institution (BSI) will be outlined which, apart from being of particular interest to those trading in Britain, serves to illustrate how the process of generating standards at a national level can be undertaken. BSI is one of the longest established and most highly rated of national standards bodies. Many other countries operate in a roughly similar manner but others will be totally different American standards are also considered, not only because of the importance and widespread use of ASTM standards, but to illustrate some of the differences in approach.

A standard method consists of a set of instructions about how to carry out a method issued by a national standards body. A national standards body is a standards body recognised at the national level - in the United Kingdom it is the British Standards Institution (BSI). The standard method will have undergone a process of public consultation with the aim of producing a clear, concise and complete method. The precision of the method will have been checked, e.g. by collaborative study (see Section 5.6). To prevent a proliferation of standard methods, a standard method may be issued by more than one body, e.g. BSI, ISO and CEN.
