All about SEAC® Full Face Mask CO2 Testing

Published

on

A feeling of fatigue and a build-up of CO2 in the respiratory system can lead to potentially serious consequences, even during low-impact physical activities like snorkelling.

That’s why SEAC® abides by two fundamental principles in designing its full-face snorkelling masks:

  • the user should need to employ the least possible breathing effort, comparable to natural breathing, out of the water and in a relaxing situation;
  • and the level of residual carbon dioxide CO2 inside the skirt while inhaling must be well below the safety limits.

Even though there is no specific European regulation governing the manufacture of full-face snorkelling masks, SEAC® has developed a series of specific tests (with their own, in-house testing equipment) that comply with the values set forth by the following European regulations:

  • EN 1972:2015 establishes the requirements for the design and manufacture of snorkel tubes, limited to breathing effort;
  • EN 16805:2015 establishes the requirements for the design and manufacture of dive masks;
  • EN 136:2000 establishes the minimum requirements for the manufacture of full-face respiratory protection masks, limited to tests checking the CO2 in inhaled air; and,
  • EN 250:2014 regarding open-circuit compressed-air self-contained breathing apparatus and its components, limited to tests checking the CO2 in inhaled air.

In the SEAC® labs, batches of full-face masks are tested with Ansti machines, specifically to measure the dynamic performance of human breathing, and with proprietary SEAC® equipment to check levels of CO2 in the air inhaled through the masks.

All this makes it possible for them to offer the end user the best possible snorkelling experience, in complete safety, because with SEAC® full-face masks, having fun is as natural as breathing!
