ASTM D8283-26

5.1 Whole-air sampling vessels are cited and utilized in a variety of international, national, and regional practices and test methods, yet the methods generally fail to uniformly specify criteria used to qualify the use and re-use of sample containers. This practice describes a set of best practices for reusable canister and other rigid gas sample containment media cleaning, quality control (QC) objectives, and corrective actions necessary to ensure equipment meets the cleanliness needs of their intended use. This best practice rigid canister cleaning standard does not evaluate the recovery of individual target compounds from canisters.

1.1 This practice describes procedures to clean and verify the cleanliness of reusable sample containers used in air sampling and analysis applications, which includes but is not limited to NiCrOx passivated stainless steel canisters, silica-lined canisters, and other prepared containers or vessels designed for whole-air sampling. This practice describes the steps used to leak check and clean substances from canister interiors and document cleanliness of blank canisters prior to re-use.

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
