Performance Standard

An indicator of a product with a clearly defined measurable parameter. A numeric rating can be applied to each standard which describe the overall quality rating for a product. For example, if using the historic PQS framework this might be 5 for high, 3 for standard, 1 for basic, or 0 for below basic, or other ratings as required. The overall rating should be seen as indicative of the entire surface, although this will depend on the extent of the sampling undertaken and if the sampling locations are generally representative of the surface.
