This document describes the procedures required to prepare all canisters, including passivated and non-passivated stainless steel canisters, all intert-coated canisters, and containers of other material specifically designed for whole-air sample analysis, for sample collection and use for laboratory analysis. This method outlines the steps necessary to internally clean the containers (all volumes) and document their acceptability for re-use. Also included are procedures for leak checking, evaluation of the condition of canisters, and canister repair.. Canister cleaning and certification is needed to ensure that each sampling container is free of contaminants and leaks that could jeopardize the integrity of the analytical data. The process must uniformly and consistently render each canister clean enough to meet the criteria for all of the relevant test methods.

Canisters are an industry standard collection device for air sampling, however there is no promulgated method outlining the upkeep, maintenance, or cleanliness criteria for these reusable items. This method streamlines efforts, and can be used in conjunction with any promulgated method for sample analysis using canisters.
