Corrosion of metals and alloys - Corrosion and fouling in industrial cooling water systems - Part 1 : guidelines for conducting pilot-scale evaluation of corrosion and fouling control additives for open recirculating cooling water systems

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.

ZOOM ON ... the Requirements department

To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.

With Requirements, quickly access the main part of the normative text!
