Selected SCUBA / Sport Diving Compressed Air Specifications

Trace Analytics, LLC specializes in the analysis of thousands of compressed breathing air samples each year. Many of our customers have established their own criteria by monitoring the performance of the system over a given time period, reviewing literature/specifications, evaluating equipment parameters, and determining company objectives. Whether you are establishing a management plan or testing to comply with a given specification, our knowledgeable staff will be glad to assist you.

Our scientifically designed compressed air testing kits make collection a simple task. Keep the small, portable kit, and return the lightweight sample via the shipping method of your choice.

Selected SCUBA / Sport Diving Compressed Air Specifications are shown below. If the specification you need is not shown, please Contact Us. We have many more air & gas specifications in our database. If you need a custom specification, Contact Us with your requirements.

(0) This specification is for applications where the CGA G-7.1 SCBA requirement for water content is employed. It combines the stricter limits of the Grades L and E.
(1) This specification is intended for applications that do not require a water content specification. CGA G-7.1-2011 has no water content limit for Grade E, for which the typical use is listed as SCUBA air. As allowed by CGA G-7.1-2011, Table 1, Note 6, water content is not specified nor reported. Note 6: "The water content of compressed air required for any particular QVL [grade] can vary with the intended use from saturated to very dry." Water ppmv and dew point is not reported.
(2) This specification is intended for applications that do not require a water content specification. CGA G-7.1-2011 has no water content limit for Grade E, for which the typical use is listed as SCUBA air. As allowed by CGA G-7.1-2011, Table1, Note 6, water content is not specified but is reported. Note 6: "The water content of compressed air required for any particular QVL [grade] can vary with the intended use from saturated to very dry." Water ppmv and dew point is reported.
(A1) This specification for oxygen compatible air is taken from ANSI/CGA G-7.1-1989 Grade E as modified by American Nitrox Divers International (ANDI) in their document Standards and Recommendations for Users, October 1994.
(I) This specification for oxygen compatible air is taken from ANSI/CGA G-7.1 Grade E as modified by International Association of Nitrox and Technical Divers (IANTD) in their document Blending Standards, 2003.
(O) Oxygen varies according to limit requested by customer.
(T) Does not include methane.
