All about SEAC® Full Face Mask CO2 Testing
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!

Cozy and warm in cold water.
It’s drysuit season all year round. With the new RS series premium drysuits from DYNAMICNORD, divers are perfectly equipped for all cold waters.
The sophisticated cut of the RS drysuits allows complete freedom of movement, providing maximum comfort. The high-quality 350 g/m² ripstop material with double ripstop zones on the elbows, knees, and crotch protect ensures extreme robustness as well as long life.
The suit’s features leave nothing to be desired: A high-quality TiZip zipper, easily adjustable inlet and outlet valves, upgradeable with electrically heated underwear, HP bottleneck cuffs made of high-strength latex on the wrists, a 3mm neoprene neck cuff for maximum comfort, a 7mm hood with air outlet and 3mm boots made of double-sided, cross-layered neoprene with ankle straps and fin strap stoppers and a protective but very flexible sole.
Noteworthy is the Molle fastening system, which can be used in a variable and compatible manner. This way, the two detachable leg pockets can be attached easily, safely and comfortably.
Alterations of boots to a different shoe size or adjustments to neck or wrist cuffs are done free of charge at the own DYNAMICNORD service centre in Germany in only a couple of days.
The matching Dynaskins made with high-quality Polartec® technology are available in various designs. As an undersuit under the drysuit, as a single suit in warm waters or as a two-piece suit. Polartec® technology’s main features are neutral buoyancy, breathablilty and quick-drying.
