What is this BS EN 14225‑1 - Wet suits – Requirements and test methods for diving about?
BS EN 14225‑1 discusses diving suits with a focus on wet suits and requirements and test methods. BS EN 14225‑1 is the first part of the BS EN 14225 multi-series on diving suits that specifies the construction and performance requirements (including thermal) of wet suits for wear by divers for underwater activities where the user is breathing underwater.
Marking, labelling, information meant to be provided at the point of sale, and instructions for use, laboratory, and practical performance tests are also specified in BS EN 14225‑1. Short sleeve jackets, short-leg trousers, under- and overgarments, and separate accessories such as gloves, hoods, and boots are not within the scope of BS EN 14225‑1.

Why should you use BS EN 14225‑1 Wet suits – Requirements and test methods?
BS EN 14225‑1 for wet diving suits has been prepared to meet the needs of persons engaged in underwater activities where the user is breathing underwater, and where water temperature and exposure duration are such that the person's thermal requirement can be met using a wet suit. A wet suit may be comprised of one or more pieces.
The thermal protection provided by a wet suit described in BS EN 14225‑1 are affected by a number of factors including the following:
- Water temperature
- Diver’s morphology (body surface area and shape, amount of body fat, sex)
- Diver’s physiology
- Diver’s rate of work and working conditions
- Thermal properties of the material of the wet suit
