The diagnosis of PK deficiency depends on the determination of quantitative enzyme activity or qualitative abnormalities of the enzyme. In 1979, the International Committee for Standardization in Haematology (ICSH) established methods for the biochemical characterization of red blood cell PK variants (M22). Since the establishment of these methods, many PK-deficient cases have been characterized, including 13 cases of homozygous PK deficiency. Residual red blood cell PK activity is not usually associated with phenotypic severity,whereas enzymatic characteristics such as decreased substrate affinity, thermal instability, or impaired response to the allosteric activator fructose-1,6-diphosphate (F-1,6-DP) correspond to a more severe phenotype.

The laboratory plays a crucial role in the detection and characterization of the hemoglobinopathies and thalassemias discussed in the next sections. There have been several recommendations for the laboratory investigation of abnormal Hbs and thalassemias. For example, the 1978 International Committee for Standardization in Hematology expert panel on abnormal Hbs has prepared recommendations for the laboratory investigation of these conditions.In its initial investigation, (1) a complete blood count (CBC), (2) electrophoresis at pH 9.2, (3) tests for solubility and sickling.

But EN 292 does not include a methodology to identify hazards and assess risks. To clarity the intent of EN 292 and to provide a framework manufacturers could consider, standard EN1050 was developed and published in 1997. Its title is Safety of machinery—Principles for risk assessment. In 1999, EN 1050 was adopted by the International Committee for Standardization as International Standard ISO 14121, without change. ISO 14121 does what it purports to do It sets forth a hazard identification and risk assessment methodology.

The method of choice for serum iron analysis has been recommended by the International Committee for Standardization in Haematology (ICSH) [42]. This reference procedure obviates problems that are inherent in convenient automated methods that are precise but inaccurate [43]. In the recommended reference method, iron is released from transferrin with trichloroacetic acid (TCA), which precipitates apotransferrin and other serum proteins that are removed by centrifugation. Fe in the supernatant fluid is reduced to Fe " with thioglycolic (mercaptoacetic) acid, which is then complexed with a chromogenic iron-chelating reagent whose color is proportional to iron concentration. 

Several countries have developed their own standard test methods for cellular plastics, and the International Organization for Standards (ISO) Technical Committee on Plastics TC-61 has been developing international standards. Information concerning the test methods for any particular country or the ISO procedures can be obtained in the United States from the American National Standards Institute. The most complete set of test procedures for cellular plastics, and the most used of any in the world, is that developed by the ASTM these procedures are pubUshed in new editions each year (128). There have been several reviews of ASTM methods and others pertinent to cellular plastics (32,59,129—131).

The development of methods of analysis for incorporation into International Standards or into foodstuff legislation was, until comparatively recently, not systematic. However, the EU and Codex have requirements regarding methods of analysis and these are outlined below. They are followed by other International Standardising Organisations (e.g. AOAC International (AOACI) and the European Committee for Standardization (CEN)). 

There are other international standardising organisations, most notably the European Committee for Standardization (CEN) and AOACI, which follow similar requirements. Although CEN methods are not prescribed by legislation, the European Commission places considerable importance on the work that CEN carries out in the development of specific methods in the food sector CEN... 

Significant progress has been made in the field of analytical detection of irradiated food to improve consumers confidence and to assist international trade of irradiated food [135,136]. Due to national and international programs and activities of the European Committee for Standardization (CEN), five validated and standardized detection methods are now available. The CEN is also considering the adoption of further five detection methods three will be screening methods (positive results from a screening method must be confirmed using a standardized method) [136].

All member countries are given equal status and are entitled to one vote regardless of size or economic development. Technical work is carried on in committees. 

The ballistic mortar test is considered to be the most satisfactory laboratory test for the measurement of the strength of an explosive. The design is based on the American company Du Ponfs design which was accepted as an international standard by the International Committee on Standardization of Tests on Explosives, Belgium in 1962. This has been described in detail by Taylor and Morris [85]. Ballistic Mortar (Du Pont Type) is used in the USA in preference to the Trauzl or lead block test which is considered to be a standard test in some European countries and is well known for research on explosives [86].

In all cases the nomenclature adhered to is that used in the original memoirs, any alteration of which must be undertaken by an International Committee. For an author to make such alterations would merely mean that another set of names had been added to those already in existence, and would tend to add to the present confusion. The author, as in Volume II., again appeals to Chemical Societies to secure some definite standard nomenclature for organometallic compounds in general. 

The International Organization for Standardization (ISO) Technical Committee (TC)146 sub-committee (SC)6 maintains the main EN ISO 16000-series of test methods for emissions testing and associated IAQ (see Table 6.1) and is working in conjunction with ISO TC 22 (cars) to harmonize associated test methods for in-vehicle air quality monitoring and emissions from car trim components.
