ASTM E645 – Antimicrobial Test – Cooling Water

ASTM E645 is an antimicrobial multi-cycle challenge test that exposes a microbicide, either alone or as formulated with standard industrial water systems, to a series of common microbial contaminates.

Microbial contamination can be presented by biocides and the biocides must be tested to show antimicrobial performance.

ASTM E645 testing is commonly used for microbicides as found in cooling water systems, industrial uses such as manufacturing, production and sanitization, as well as in water-based products where microbial growth may impact the quality of the water source, industrial process, or end- product.

This antimicrobial test method demonstrates the effects that representative microbes have on microbicides commonly seen in actual use – opening and closing of container, vat, or pipe, and the constant inoculation of the biocide-treated water source with environmental organisms or organisms commonly associated with standard industrial processes.

Evaluation and testing can provide important data about a microbicides performance while in use in a cooling water system.

Typically tested to standard bacteria and fungal challenges, ASTM E645 is often modified to include specific organisms, depending on the needs of the end-customer.

Options include a wide range of bacteria, fungi and algal cultures as well as custom time-points and cycle lengths.

Once exposed to microbial populations, the ability of the preservative to withstand initial contact and subsequent re-inoculations helps to determine the effectiveness of a particular preservation system and/or formulation.
