Question

Accepted Answer

In alignment with international standards such as EN 12021, “air” refers to atmospheric or natural air composed of 78% nitrogen, 21% oxygen and 1% traces of other gases such as argon, carbon dioxide and water vapour. This includes air mixtures within 10% variation from atmospheric or natural air composition – for example, where oxygen content varies from standard 21% to between 19% and 23%.
