Inspection updating techniques

Updating quality control and inspection and testing techniques (4.2.3.1c)... 

When needed to achieve the required standard of quality, quality control, inspection techniques, and instrumentation are updated. As needed to achieve the required quality, any controls, processes, inspection equipment, fixtures, total production resources, and skills are identified and acquired. 

The updating, as necessary, of quality control, inspection, and testing techniques, including the development of new instrumentation... 

Experimental testing under pressure of a test combustor, even if simplified and reduced, constitutes a difficult and expensive problem (safety, inspection, size, fluid supply, etc.), and it can be carried out by specialized organizations only. Industrial prototypes of GT combustors are tested in scale 1 1 during short (very expensive) trials updated, laser-based, diagnostic optical techniques are employed to squeeze as much experimental information as possible to be subsequently supplied to mathematical modelers for quantitative data processing. A detailed insight into the GT sector is out of the scope of the present book and it has been quoted only to remind researchers that testing may become extremely expensive and complicated. 

Sherma and Fried (8) reviewed in detail a number of techniques easily applicable to quantitative TLC. Major techniques included colorimetry and visual inspection, zone elution (scraping) for HPLC, spectrometry, GC, voltammetry, densitometry, and radiochemical techniques. Other studies added to and updated this material with computerized radiochemical, laser densitometric, and phosphoroima-ger techniques (56-61). 

The risk assessment must be maintained. This means that any significant change to a workplace, process or activity, or the introduction of any new process, activity or operation, should be subject to risk assessment. If new hazards come to light, then these should also be subject to risk assessment. The risk assessment should in any case be periodically reviewed and updated. This is best achieved by a suitable combination of safety inspection and monitoring techniques, which require corrective and/or additional action where the need is identified. Typical monitoring systems include ...
