NDT as an objective method, which can be applied for 100% control if necessary, is used for quality assessment of critical components all over the world. But it is necessary to support quality of the implementation of NDT to ensure the detection of defects and to achieve reliable results. 

The specific character of NDT related to the quality assessment of safety critical products and objects requires constant analysis and continuous improvement of processes and their interconnection. Sometimes interaction of processes is very complicated (Figure 3) therefore the processes have to be systematized and simplified when possible to realize total quality management in NDT. 

It must be remarked that terminology is not consistent and there are many widely used synon)ms. Quality control in this Chapter refers to practices best described as internal quality control. Quahty assessment is often referred to as external quality control, proficiency testing, interlaboratory comparisons, round robins or other terms. Internal Quality Control and External Quality Assessment are preferred because they best describe the objectives for which the RMs are being used, i.e. the immediate and active control of the results being reported from an analytical run or event, and an objective, retrospective assessment of the quality of those results. 

In 1978 the International Federation of Clinical Chemistry produced a comprehensive summary of the objectives of External Quality Assessment (IFCC 1978). The first six points of Table 4.1 summarize the IFCC objectives the seventh has developed since that time and is of considerable importance in many countries where strict control over laboratories undertaking particular types of work is required by legislation or by appropriate professional organizations. 

The CMT method was primarily developed to replace traditional corrosion tests with a faster, quantitative test. Since the course of corrosion with time is continuously shown on the screen, it is easy to see if and when a stable situation has been established, resulting in a constant rate of corrosion. The rate of corrosion at that stage can often serve as a safe measure of the lifetime of the object. An assessment of quality on the basis of such a measurement can be made in a much shorter time than by a chamber test. In the latter, a good quality product should typically have a time to failure of more than 100 h, whereas a CMT test of a similar product mostly shows a stable, constant rate of corrosion (on the order of 5-10 fiAJcrn ) after less than 2 h. 

All details about starting materials and central production features should be known, in order to define exactly the status natural of a flavouring substance. In principle, the burden of proof is the responsibility of the producer. If necessary, production documents should be disclosed, in order to get objective authenticity assessment by qualified and authorised experts. Constructive cooperation between food researchers, the food industry and authorities will be stimulating to quality assessment in the food industry and will enhance consumer confidence [83].

As with satisfaction, there is a rich history concerning the concept of quality. A broad definition of quality is superiority or excellence. Researchers note a difference between objective quality (i.e., measurable and verifiable superiority on some predetermined ideal standard) and perceived quality (Zeithaml, 1988). Perceived quality is a global assessment made by a consumer that is posited to exist at a higher level of abstrac-... 

For non-SI traceable quantities the predominant objective must be an agreement on the definition of these quantities on an international basis before reference measurement procedures can be developed and used for assigning target values in external quality assessment. 

Comparisons between the results obtained using different pyrolysers are not uncommon in literature [16,34-36]. These comparisons have two objectives to assess the quality of the analytical results (reproducibility, sensitivity, etc.) of a certain type of pyrolyser and to indicate how the results of one pyrolyser can be compared to those of another type. 

In Contingencies of Value, Barbara Smith (1988) argues that values are not "fixed" or "objective" qualities, but they are "an effect of multiple, continuously changing, and continuously interacting variables" (30). Likewise, Scott and Susanmarie s DCM work with their colleagues, which produced the dynamic rubric s richly synthesized and interwoven criteria descriptions, illustrates how assessment values are contingent upon their rhetorical interrelationships and contexts.

A) determination of the occurrence and distribution of chemicals in Lake Pontchartrain, Louisiana (particularly in the southern portion of the Lake near New Orleans) that resulted from anthropogenic activity and (B) an overall water quality assessment of the Lake to ascertain any phenomena, in particular urban runoff related water pollution, that may be adversely affecting the ecological balance of the Lake. The strategies developed to address these objectives included (1) Collection of biota and sediment samples and their analyses for a broad spectrum of chemical substances which included, but were not limited to, those designated as priority pollutants by the U.S. 

Fig. 1.3, The quality spiral described in Fig. 1,1 and its implementation depend on the tools available in the laboratory. These tools concern laboratory structure, personnel, management, external and internal quality assessment measures. The proper use of the available tools will lead to the development of the quality objectives (adapted from ref [10]).
