    Abstract - (Show below) - (Hide below)

    ISO 16784-1:2006 applies to corrosion and fouling in industrial cooling water systems. ISO 16784-1:2006 covers the criteria that must be defined and implemented in a pilot-scale testing programme to select water treatment programmes for use in specific recirculating cooling water systems.ISO 16784-1:2006 covers only open recirculating cooling water systems. Closed cooling systems and once-through cooling water systems are specifically excluded.The test criteria established in ISO 16784-1:2006 are not intended to govern the type of bench and pilot-scale testing normally carried out by water treatment companies as part of their proprietary product-development programmes. However, water treatment companies may choose to use the criteria in ISO 16784-1:2006 as guidelines in the development of their own product-development test procedures.
