Quality assurance general

The Toyota X300 fork lift truck project design cycle is concurrent in nature spanning all the major disciplines in the process with quality assurance reviews, stipulating the use of appropriate tools and techniques at certain points. The product development process produced by General Electric is called the Tollgate Process . Again, it is concurrent in nature and includes ten review points. 

The 1982 White Paper on Standards, Quality and International Competitiveness was concurrent with increasing interest in the techniques of quality assurance and the need for international harmonization of standards and the reciprocal recognition of certification. It is worth noting that the ISO 9000 series of standards on Quality Systems 1987 followed the layout of BS 5750 1979 almost clause by clause. ISO Guide 39 covers the general requirements for inspection bodies. Auditing on behalf of certification bodies is part of the inspecting authorities role. 

This feasibility study shows that determination of pellet wt by fast neutron oxygen activation analysis can be used for quality assurance inspection of M34 primers. Either direct oxygen analysis, where a comparison standard (such as lucite) is used, or a ratio method, utilizing the Cu in the cup-anvil combination as an internal standard, can be applied. In general, the uniformity of production primers is quite satisfactory, as is usually the case where production procedures are standardized. It seems likely that the light pellet is one which has been improperly manufd and will probably be well below specifications in pellet wt. Production experience with such primers indicates that only one in 3x10s primers is expected to show low pellet wt therefore, one would not expect to find a reject in a small sampling. Nevertheless, detection and rejection of this one bad unit is critical for the prevention of weapon malfunctions and possible injuries to personnel... 

Medicinal products and bulk pharmaceutical chemicals are produced mainly in batch processes. Controlling these products and chemicals at the end of their manufacturing processes is not in line with the general principle of quality assurance, which is that quality should be built into the product. It is then necessary to ensure that appropriate good manufacturing practices are adhered to throughout the manufacture of both bulk pharmaceutical chemicals (active ingredients as well as excipients) and medicinal products. 

The revised database holds over 23 000 analyte values for 660 measurands and 1670 reference materials produced by 56 different producers, from 22 countries. The database is restricted to natural matrix materials (i.e. made from naturally occurring materials, excluding calibration standards manufactured from pure chemicals). Information has been extracted from the relevant certificates of analysis, information sheets, and other reports provided by the reference material producers. As a general rule, the authors have only included in the compilation reference materials for which a certificate of analysis or similar documentation is on file. Information included in the survey is on values for measurands determined in reference materials, producers, suppliers, the cost of the materials, the unit size supplied, and the recommended minimum weight of material for analysis, if available. The new searchable database has been designed to help analysts to select reference materials for quality assurance purposes that match as closely as possible, with respect to matrix type and concentrations of the measurands of interest and their samples to be analyzed see Table 8.3. 

Food products can generally be considered as a mixture of many components. For example, milk, cream and cheeses are primarily a mixture of water, fat globules and macromolecules. The concentrations of the components are important parameters in the food industry for the control of production processes, quality assurance and the development of new products. NMR has been used extensively to quantify the amount of each component, and also their states [59, 60]. For example, lipid crystallization has been studied in model systems and in actual food systems [61, 62]. Callaghan et al. [63] have shown that the fat in Cheddar cheese was diffusion-restricted and was most probably associated with small droplets. Many pioneering applications of NMR and MRI in food science and processing have been reviewed in Refs. [19, 20, 59]. 

The design of an assay is, in large measure, prospective quality assurance. The factors that are likely to affect the results of the assay must be defined and controlled to the greatest extent possible. Once the general outlines of an assay have been established, key features should be examined, including optimization of sample preparation, sample stability, choice of standards, assay range, assay repeatability, optimization of separation, and optimization of detection. 

The terms quality assurance and quality control are sometimes used interchangeably, but there is an important difference. Quality control generally refers to testing of raw materials, packaging components, and... 

Precision farming techniques and split applications adapted to micro-sites and specific to the demand of the crop might be a quality assurance tool for conventional farming in the future. Since input rate has shown significant effects on FHB development in wheat, lower amounts of nitrogen, both applied or available from the soil, may generally result in reduced FHB as well as DON contamination. 

General Principles of Quality Assurance and Quality Control... 

This Standard is a very general document and does not cover technical aspects. However, analytical laboratories increasingly have selected certification to ISO 9001 to cover the broader aspects of their activities. The earlier versions of this Standard had the term quality assurance in the title but this has now been removed. The reason is that the current standard requires more than quality assurance of the service. Enhancement of customer satisfaction is also expected, along with evidence of continuous improvement. In Figure 2.2, this is covered in the box dealing with evaluating the results. 

A variety of measurement methods have been developed for determining the water activity of food materials and are well described in texts such as Rahman (1995), Wiederhold (1997), and Bell and Labuza (2000). In general, water activity is a relatively easy parameter to measure, which can be an advantage, especially for use in the food industry. Depending on the technique selected, the water activity of a food material can be measured in a time frame of minutes (e.g., electronic instrument). In addition, individuals can be trained, with a limited amount of instruction, to make water activity measurements. Consequently, when appropriate, water activity measurements can be made relatively quickly by personnel overseeing a manufacturing line for quality assurance purposes. Measurement protocols, such as calibration procedures and proper temperature control, should be implemented to assure the accuracy of online c/w measurements. 

The food polymer science approach is being applied successfully in the food industry for understanding, improving, and developing food processes and products. However, to date, the glass transition generally remains more of a research and development tool than a routine quality assurance measure of food processability and stability. 

Member States shall take all measures necessary to ensure that the laboratories referred to in Article 7 of Directive 89/397/EEC1 comply with the general criteria for the operation of testing laboratories laid down in European standard EN 450013 supplemented by Standard Operating Procedures and the random audit of their compliance by quality assurance personnel, in accordance with the OECD principles Nos. 2 and 7 of good laboratory practice as set out in Section II of Annex 2 of the Decision of the Council of the OECD of 12 Mar 1981 concerning the mutual acceptance of data in the assessment of chemicals.4... 

Because of the diversity of potential field testing and sampling activities during the characterization, there may be no specific quality assurance (QA) activities that apply to all sampling procedures. However, the following general QA principles would apply in most cases and are consistent with the QA guidelines published by USEPA s Environmental Response Team ...

United States. GMP is defined by the FDA as a federal regulation setting minimum quality requirements that drug, biologies and device manufacturers must meet. It describes in general terms known and accepted quality assurance principles for producing these products. Its components are scientific understanding, documentation, analysis and measurements and personnel matters. Its intended result is total quality assurance and product control. ...
