What governing standard and construction define UDA0103 / UDA0104 (UDA0103 / UDA0104 3- & 4-Part Surface-Demand Diving Umbilical)?

UDA0103 / UDA0104 (UDA0103 / UDA0104 3- & 4-Part Surface-Demand Diving Umbilical) is manufactured in accordance with IMCA D 014 / IMCA D 078 / EN 12021 Diving Standard for 600 V service over -30 °C to +70 °C. Its 5-layer construction comprises breathing gas hose (hda0106, 3/8" id), pneumofathometer hose (hda0104, 1/4" id) and tapeless helical rope-like lay-up.

What is the minimum bending radius and operating temperature range for UDA0103 / UDA0104?

The minimum bending radius for UDA0103 / UDA0104 is 8 × OD across its continuous operating temperature range of -30 °C to +70 °C, ensuring mechanical and dielectric reliability in subsea, marine and submersible service.

How are the concentric layers of UDA0103 / UDA0104 arranged from inside to outside?

From inside to outside, the construction sequence is: (01) Breathing Gas Hose (HDA0106, 3/8" ID) — Clean low-VOC core tube + high-strength yarn braid + blue cover (500 psi WP / 2,000 psi burst); (02) Pneumofathometer Hose (HDA0104, 1/4" ID) — Low-VOC core tube + yarn braid + yellow cover (300 psi WP / 1,200 psi burst); (03) Hot Water Supply Hose (HDA1108, 1/2" ID) — Clean thermoplastic tube + yarn braid + red cover (300 psi WP, in 4-part UDA0104); (04) Diver Comms / Video Cable Unit — 4-core shielded diver communication (or 75 Ω coax video/light hybrid in UDA0204); (05) Tapeless Helical Rope-Like Lay-Up — Planetary contra-helical cabled assembly with controlled buoyancy (-20 to -56 g/m).

What factory test certificates are supplied with UDA0103 / UDA0104?

Every production drum of UDA0103 / UDA0104 undergoes routine conductor resistance/continuity, high-voltage dielectric and dimensional testing per IMCA D 014 / IMCA D 078 / EN 12021 Diving Standard, and is delivered with an EN 10204 3.1 factory test certificate.
