Overview

EN 15333-1:2008 is a CEN European Standard that defines minimum safety and performance requirements for open-circuit umbilical supplied compressed gas diving apparatus - Part 1: Demand apparatus. It covers demand surface‑supplied and surface‑oriented diving equipment for typical recreational, commercial and work diving operations within specified depth and gas‑mix ranges and environmental conditions. The standard is intended to ensure safe interaction between the wearer, the apparatus and the operating environment.

Key scope points:

• Applicable to air, oxygen or oxygen‑in‑nitrogen mixtures to 0–50 m depth.
• Applicable to oxygen/helium or oxygen/nitrogen/helium mixtures to 0–60 m depth.
• Water temperature range: 4 °C to 34 °C (or other ranges when declared by the manufacturer).
• Excludes saturation systems, mini bell systems and oxygen‑decompression‑only apparatus.

Key Topics and Requirements

The standard addresses both design and verification requirements across the apparatus lifecycle, including:

• Design & materials: structural and material requirements for diver‑worn components and connectors.
• Pressure systems: requirements and tests for high/medium pressure parts, pressure reducers and pressure relief systems.
• Hoses & umbilical: tensile strength, flexibility, burst/leak tests, buoyancy and life‑line features.
• Breathing system performance: demand valve behavior, exhalation valve, CO2 clearance limits and hydrostatic imbalance.
• Facepieces & helmets: mechanical connections, visors, field of vision, impact protection and harnesses.
• Safety devices & monitoring: pressure indicators, optional depth and oxygen monitoring, pressure surge/oxygen compatibility.
• Functional and environmental testing: cold/warm temperature resistance, seawater exposure, cleaning/disinfection and sea trials/practical performance tests.
• Communications & electronics: voice systems, recording, electrical functional safety and noise assessments.

Applications

EN 15333-1:2008 is used to:

• Define minimum safety/performance criteria for surface‑supplied open‑circuit demand diving kits.
• Guide product design and material selection for manufacturers of umbilical supplied diving equipment.
• Serve as a test and acceptance benchmark for test laboratories and certification bodies.
• Inform procurement specifications and equipment audits by diving contractors, commercial diving teams and safety officers.
• Support training and operational procedures by clarifying performance expectations under standard test conditions.

Who Should Use This Standard

• Diving equipment manufacturers and designers
• Test houses, conformity assessment and certification bodies
• Commercial diving companies, vessel operators and safety managers
• Technical authors preparing equipment specifications or compliance documentation
• Regulators and procurement teams specifying safe surface‑supplied diving systems
