The commercial transportation industry represents a significant portion of global energy demand and contributes a significant amount of global greenhouse gas emissions. Compressed Natural Gas (CNG) provides an economically viable option for the transportation sector to contribute to decarbonization.

Cheaper, cleaner, and abundantly available, CNG is formed when natural gas is compressed to less than 1% of the space it would normally occupy in the atmosphere, where it is then stored in special cylinders for use. Working with the automotive industry and other relevant stakeholders, CSA Group facilitated the standards that are often used today for the fuel dispensing, storage, and infrastructure needed to operate natural gas vehicles. Our years of experience working with stakeholders in the automotive and related industries has provided us with extensive in-depth technical knowledge that our customers have come to expect.

CSA Group performs testing & certification to North American and International CNG tank & component standards and regulations including CSA/ANSI NGV 1, CSA/ANSI NGV 2, and the European UN ECE R110 regulation. Our state-of-the-art ISO 17025 accredited laboratories utilize the latest equipment and techniques to perform hydraulic pressure testing, CNG testing, fuel system & component testing, and remote field testing. Our capabilities also cover the evaluation of the performance of CNG fuel systems under extreme service conditions, including severe penetration, crush, crash, and fire events. CSA Group test reports are accepted by regulatory authorities such as U.S. DOT, Japan KHK, German KBA, and Luxembourg SNCH, helping our customers to achieve global type approvals via a single provider.

In addition to our testing & certification solutions, we offer a full suite of standards, training, and personnel certification programs to support the CNG industry, as well as a database to help find qualified CNG cylinder and fuel system inspectors in your area.
