What is the standard practice for the accuracy of enriched air analysis?

The standard practice for the accuracy of enriched air analysis is typically within plus or minus 1%. This level of accuracy is crucial for divers who use enriched air nitrox because it allows them to accurately assess the oxygen content of the gas they will be breathing. Accurate analysis is important for planning dives, especially regarding exposure limits to oxygen, which can lead to oxygen toxicity if not managed properly. Maintaining this standard ensures divers can make informed decisions about their dive profiles and avoid potential risks associated with incorrect gas mixtures. The other levels of accuracy provided are generally considered too loose for a safe diving standard, where precision is pivotal for diver safety.
