The direct measurement of a wound pH is limited by the availability of suitable probes even needle-style pH probes cause tissue dismption and localised cell death. As a result of these limitations, the available data is restricted to the measurement of wound surface pH or wound exudate pH. The wound pH measurement should be simple, accessible, sensitive, precise, reproducible, and should cause minimal or no discomfort to the patient (Shukla et al., 2007). The British Standard test method BS 13726 2002 appears to have attempted to test and analyse only the physical characteristics of the... 

Phenol Coefficient Test. The first important attempt at standardizing testing methods was known as the phenol coefficient test (96). It has been modified several times, and is an official AO AC screening test recognized by EPA and PDA. The phenol coefficient test compares the activity of disinfectants to that of phenol, under specific conditions, to give a number that measures the activity of the chemical tested with respect to that of phenol, ie, the phenol coefficient. The AO AC method employs visual examination of bacterial growth in a nutrient medium. The Kelsey-Sykes test (1969) is a modified method popular in British circles.

There are no ISO, ASTM or British fire test method standards specifically for solid mbbers and there is no active fire test work being pursued in TC 45. There are, however, a number of published international test methods for cellular materials and plastics, the majority of which could be applied to rubbers. A comprehensive account of fire testing of plastics has been given by Paul in the Handbook of Polymer Testing81. There may be fire resistance requirements for particular rubber products and some examples were given by Schultz110.

Remember that British Standard BS 5532 [CAULCUTT and BODDY, 1983] provides qualitative and quantitative definitions of both reproducibility and repeatability. The determination of repeatability and reproducibility for a standard test method by interlaboratory tests is given in [ISO 5725]. 

In the past, different countries had their own textile standard testing methods.79 Since 1990 within EU, there has been an attempt to normalize these standards. In the United Kingdom, for example, most new British Standards are prefixed by BS EN or BS EN ISO. Most of the test methods are based on the principle that test should be straightforward and easy to apply, and are application specific. The standard test methods usually involve pass-fail or performance rating criteria10 and are mostly product application specific. Some selective and more relevant test methods are discussed here in brief, and for detailed information the reader is referred to a recent review by Nazare and Horrocks.11...

This chapter is aimed at expanding upon the listings of standard test methods presented in the following Chapter 11 on Standardization Documents. The first section of the chapter lists 130 properties of cellular plastics and elastomers and tabulates the standard test methods (U.S., ISO and British Standards) known to be applicable to each. Only number designations are given. The reader will find the titles and complete citations for the standards in Chapter 11. A key to the symbols used is given to indicate the type of cellular materials used (flexible or rigid) and a number of other matters of interest. 

Standard test methods that have been trialled, tested and approved by independent committees are the main methods accepted by government purchasing departments, manufacturers and quality assurance systems. Many traditional British Standards have been incorporated into International Standards (ISO) and European Norme (BS EN) standards for use throughout the world. The following list contains some of the important test methods for the chemical analysis of rubbers, plastics and other elastomers used in coated fabrics.

There are a large number of standard test methods available for paints to ensure that specific performance criteria are met. The most widely used standards originate from the American Society for Testing and Materials (ASTM), British Standards Institution (BSI), Deutsche Institut fiir Normung (DIN), and the International Organization for Standardization (ISO). The methods used will depend on the paint type and intended application. A selection of methods is described below that are likely to be used for water-based coatings.

Coefficients of fiiction of light conveyor belts are determined according to European standards.A metallic test panel under load, which generates together with the panel a normal force of 50 N, is pulled on the surface of a test piece. Forces required to initiate movement and maintaining it are recorded and results used for calculation of static and dynamic coefficients of friction. ISO, and the identical British standard, contain method of determination of frictional proper-...

A new standard test method is clearly required that will accommodate 0x0-biodegradable plastics and satisfy environmentalists that these materials are fully biocompatible. The British Standards Institution (BSi PKW/0 Packaging and the Environment ) and ASTM (D 20.96) are currently developing alternative mineralisation proeesses for oxo-biodegradable plastics that incorporate controlled pre-ageing processes before the mineralisation test. The protocol shown in Fig. 12.5 outlines the BSi twin-track route to mineralisation. Key features of the test method are as follows.

Benzaldehyde is sold as technical grade or as meeting the specifications of the NationalVormulary (NF) (7), the Vood Chemicals Codex (FCC) (8), or the British Pharmacopeia (BP) (9) (Tables 4 and 5). The test methods used for the analysis of benzaldehyde are standard methods, with the exception of the assay method.

The effects of corrosion on other properties need similar direct assessment in many cases. However, in the absence of accepted standard tests the BS, DIN, ISO tests for laboratory glassware are often used. At the present time, the British Standard BS 3473 Methods of testing and classification of the chemical resistance of glass used in the production of laboratory glassware is being re-issued in six parts, of which the first five parts are identical to recently revised ISO test procedures. There are also corresponding DIN tests in some cases which are very similar. The current situation is ...
