The versatility of hydraulic sprayers enables them to be used in a wide variety of situations. There are BSI standards for the compression and lever-operated knapsack sprayers. The relatively inexpensive compression sprayers have a small air pump to pressurise a container of 0.5-10 litre capacity, which is filled with the spray liquid to about three-quarter capacity. Pumping is not required while... 

Tests other than those quoted in this chapter can be found as ISO, ASTM, TAPPI and BSI standards. In most tests on paper and board, the materials have to be conditioned prior to testing, otherwise compatible results will not be achieved. See Tables 22-2.1.

Secondly, the imperfect protective clothing standardization system in our country, and the western countries to produce all kinds of protective clothing, protective clothing performance test method standard is also very complete, high standardization degree, has formed a relatively perfect standardization system. EN standards system such as the European Union, the United States ANSI standard system, Japanese JIS standards system, German DIN standard system and the British BSI standards system. The most perfect is the international organization for standardization system of ISO standards. 

For testing plastics, a wide spectrum of national standards have been practiced worldwide— for instance, American Society for Testing and Materials (ASTM) standards in the United States, Deutsches Institut fiir Normung (DIN) in Germany British Standards Institution (BSI) standards in the United Kingdom, Association Fran aise de Normalisation (AFNOR) standards in France, and Japanese Industrial Standards (JIS) in Japan (Fig. 11.2).

The aim is to exclude unsafe electrical equipment from being marketed in the EU. To ensure this, the equipment has to comply with the relevant harmonised standard in the absence of such a standard, to an International Electrotechnical Commission (lEC) standard or, failing this, to a BSI standard. The manufacturer has to test the equipment himself to prove its safety or have it tested, preferably by an approved testing laboratory, and make a declaration of conformity with the relevant standards. He has to maintain technical documentation containing prescribed information and from 1 January 1997 had to apply the CE mark to the product, or its packaging, or its instruction sheet, or its guarantee certificate.

The national organizations are often relayed into each profession by a body created and financed by this profession and which undertakes all or part of the work in preparing the standards. In the petroleum industry, this role is carried out in France by the BNPet (Bureau de Normalisation du Petrole) and in Germany by the FAM (Fachausschuss Mineralol-und Brennstoffnormung), in the United Kingdom by the IP (Institute of Petroleum), and in the USA by the ASTM (American Society for Testing and Materials). In the first two cases, the standards are published only by the national organizations (AFNOR and DIN respectively), while the IP and the ASTM also publish their own documents, only some of which are adopted by the BSI and ANSI, respectively.

In 1983, BSI approached the International Organization of Standardization in Geneva with a view to developing an international quality system standard and eventually a committee was formed. Using BS 5750 as its basis, the ISO 9000 series of standards was born.

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. 

The BSI perspective is quite different from that of ASME. It includes considerable information on water treatment chemicals and tackles its standard with a strong chemistry emphasis, whereas the ASME Consensus maintains an engineering stance. 

The BS 2486 1978 water chemistry table for FT plants categorized boilers by FW hardness (unlike the 1997 revision, which charted by heat flux, and the ASME Consensus, which uses pressure to define boiler groups). This 1978 edition has been withdrawn by BSI. However, for the purposes of providing guidelines for those many thousands of smaller FT boiler plant owners around the world (especially those in newly industrializing countries) operating lower heat-flux units and without benefit of first-class pretreatment, it remains a valid standard. 

NOTE As an example, 90% of water supplied to New York City has a total hardness below 15 to 20 ppm CaCOy Pretreatment softeners are not the norm and consequently there are many thousands of nondomestic LP steam boilers (in addition to greater numbers of domestic LP steam boilers) in daily operation, where the FW hardness is 2 to 5 ppm or more as CaCOy The BSI 2486 1978 table for shell boilers remains a valid standard for these commercial and institutional boilers.
