CE Marking for diving equipment: understanding the standards, testing procedures, and the role of Notified Bodies
CE marking is a crucial step for any manufacturer wishing to market diving equipment in Europe. Whether it’s a regulator, a dry suit, a rebreather, or a harness, every product must demonstrate compliance with the essential safety requirements. Yet the regulatory process can quickly become complex: Which standard applies? What tests are required? What is the precise role of a testing laboratory compared to that of a Notified Body?
This article provides a clear overview of the obligations, key standards, and technical resources that support manufacturers throughout their certification process.
CE requirements: a mandatory step for diving equipment
In the world of personal protective equipment designed for diving, CE marking generally relies on two key steps. First, the EU Type Examination (Module B) assesses a prototype to ensure it meets all regulatory requirements. Then, Module C2 completes the process through regular inspections of production samples.
These procedures are carried out by a Notified Body, an independent authority authorized to review technical documentation, verify conformity, and issue CE certificates.
The standards governing diving equipment
Every category of diving equipment is linked to a specific standard, and this is often the first question manufacturers ask when they begin the certification process. Regulators, for example, fall under EN 250, which defines requirements for breathing performance, cold-water behavior, and the “work of breathing.” Rebreathers, being more complex systems, are assessed according to EN 14143, which covers gas-analysis requirements and performance during dynamic immersion.
Diving suits, whether wet or dry, are regulated by EN 14225-1 and EN 14225-2, while buoyancy compensators (BCDs) must comply with EN 1809, which specifies criteria for buoyancy, material resistance, and dump-valve systems.
Additional standards apply depending on the product type:
- ✓EN 13319 for dive computers
- ✓EN 15333-1 or harnesses
- ✓ISO 12402 for inflatable life jackets
- ✓Emergency Breathing Systems (EBS), a rapidly expanding category, which requires specific respiratory performance testing
This comprehensive framework ensures a consistent level of safety across Europe.
Notified Body and Test Laboratory: two complementary roles
Within the CE marking process, two distinct actors are involved, and it is important to understand their respective roles.
The Notified Body is responsible for regulatory assessment. It reviews the technical documentation, ensures that the tests performed meet the applicable standards, and—if everything is compliant—issues the certificate required for CE marking.
The test laboratory, on the other hand, carries out the technical measurements needed to validate the product’s performance. It is the laboratory that tests the regulator, measures the breathing performance of a rebreather, or evaluates the buoyancy characteristics of a BCD.
In practice, manufacturers typically begin with a test laboratory to conduct the required assessments, then submit the resulting reports to the Notified Body as part of Module B or Module C2.
The importance of specialized testing capabilities
Testing equipment intended for underwater use requires laboratory infrastructure capable of reproducing real-world conditions.
One of the most critical devices is the respiratory simulator, often referred to as an “artificial lung.” It precisely measures the breathing performance of regulators or rebreathers by reproducing different workload cycles. This instrument is essential for conducting tests in accordance with EN 250 and EN 14143.
Textile equipment, harnesses, and wearable devices require mechanical testing, carried out using tensile machines that assess material resistance and deformation..
Finally, to validate how equipment behaves in actual immersion, tests may be performed in a dedicated test basin or a 10-meter dive pit, sometimes directly with experienced divers. This makes it possible to verify specific elements such as buoyancy, comfort, activation of safety systems, and overall stability of the equipment.
Supporting manufacturers: from prototype to CE pre-testing
More and more manufacturers are seeking guidance from the earliest stages of product development. Pre-tests can be carried out to identify potential non-conformities before the official assessment by the Notified Body..
This support may include:
- ✓Developing a tailored testing protocol,
- ✓Adjusting test conditions to match the product’s specific features
- ✓Conducting exploratory sessions to anticipate target performance values,
- ✓Performing dynamic immersion tests ahead of the formal regulatory phase.
This approach helps secure market readiness, avoid delays caused by inconclusive tests, and reduce costs linked to late-stage design modifications.
Conclusion
Achieving CE marking for diving equipment requires a thorough understanding of the applicable standards, the execution of specialized tests, and the involvement of a Notified Body to validate the entire process. With the right testing capabilities—respiratory simulators, tensile machines, and immersion trials—a specialized laboratory can effectively support manufacturers from early product design all the way to certification.
