1.1 The Surber, portable invertebrate box, Hess, Hess stream bottom, and stream-bed fauna samples are qualitative and most are reasonably quantitative collecting devices. They are operated by hand. They provide for outlining a definite unit-area, for collecting the macroinvertebrates within the area, and are equipped with a net to retain organisms. They are designed to be placed by hand onto or in some cases into mud, sand, gravel, or rubble substrate types, in shallow streams, or shallow areas of rivers.

1.2 The drift net sampler is a qualitative and quantitative collecting device used to capture drifting organisms in flowing waters.

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.
