Historical Standard: ASTM D5495-94(2001) Standard Practice for Sampling With a Composite Liquid Waste Sampler (COLIWASA)
SUPERSEDED (see Active link, below)
ASTM D5495
1. Scope
1.1 This practice describes the procedure for sampling liquids with the composite liquid waste sampler, or 'COLIWASA.' The COLIWASA is an appropriate device for obtaining a representative sample from stratified or unstratified liquids. Its most common use is for sampling containerized liquids, such as tanks, barrels, and drums. It may also be used for pools and other open bodies of stagnant liquid.
Note 1--A limitation of the COLIWASA is that the stopper mechanism may not allow collection of approximately the bottom inch of material, depending on construction of the stopper.
1.2 The COLIWASA should not be used to sample flowing or moving liquids.
1.3 This standard does not purport to address all of the safety problems, 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.
