Guidelines for Quality Assurance of Installed Fine-Pore Aeration Equipment
|Publication Date:||1 January 2002|
The methods described under these standard guidelines provide several techniques for use in developing quality assurance requirements for specifying fine-pore aeration equipment. The guidelines are for the practice of quality assurance. Quality assurance is practiced by users to control the quality of the product provided to a user at a specified acceptable level. In contrast to quality assurance, quality control is practiced by manufacturers to control the quality of production at a specified acceptable level.
Although quality assurance and quality control practices can be considered as independent activities, their goals are essentially the same: to ensure that the consumer receives quality equipment on time for the contracted price.
Quality assurance benefits all parties involved in the manufacture, specification, and use of aeration equipment. For the manufacturer, standardized quality assurance should reduce the number of indefinite or unrealistic specifications and enhance the probability of achieving unequivocal specifications and improved understanding between supplier and user. For the designer and the ownerhser, confidence that the performance of the aeration equipment at start-up meets the design performance criteria will be substantially improved. For the industry as a whole, application of consensus quality assurance methods is likely to result in improved quality and reliability and more favorable life cycle costs.
The designer and ownerhser must consider the costs associated with quality assurance testing when developing and specifying quality assurance testing requirements. The testing requirements should be discussed with the manufacturers to ensure that the project objectives are achieved.
