1.1 This practice covers the determination of the susceptibility of polymeric films to the attachment and proliferation of surface-growing algae.

1.2 The values in SI units are to be regarded as the standard. The inch-pound units given in parentheses are for information only.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.


3.1 Bodies of water, such as swimming pools, artificial ponds, and irrigation ditches often are lined with polymeric films. Algae tend to grow in such bodies of water under the proper atmospheric conditions, and they can produce slimy and unsightly deposits on the film. The method described herein is useful in evaluating the degree and permanency of protection against surface growth of algae afforded by various additives incorporated in the film.
