Testing
and certifications

_ The full control experienced by users of Hydpro products is based on our high level of expertise in technology and an integrated manufacturing process.
This begins with the design and research-and-development stages and ends with the final testing: it is a process that allows us to produce virtually all components internally.
Moreover, constant attention to European regulations means we easily obtain all initial conformity certifications from the agencies and authorities in charge.
Within our own laboratories, Hydpro has all the machines and equipment needed not just to test the compliance of our products with legal requirements, but also to verify their reliability and durability.
Identification and traceability are at the core of the Hydpro Quality System.
Each product has its own serial number, giving us a detailed overview of every single component’s production cycle, looking from the pre-market tests all the way back to the batch of raw materials used to manufacture it.
The uncompromising quality of Hydpro products is a result of this process.

INFLATORS

Our inflators undergo 136 different tests.
The main tests include:

  • Airflow test, by which a device’s airflow is measured in nl/h

  • 100% underwater product test, demonstrating a device’s total functionality before it can be marketed

  • Tensile strength test, evaluating resistance to dynamic tensile strength (measured in N/sec) and compliance with legal requirements

  • Test for resistance to pressure at 20 and at 30 bars, testing the system’s functionality and demonstrating there is no free flow, in compliance with legal requirements

  • Flow rate test with variable air density, measuring the air flow rate drop, as expressed in nl/h, in relation to depth

  • Cyclical wear tests, evaluating the system’s wear limits

  • Ageing tests in salt mist and climate chamber, determines resistance to ageing and to environmental conditions

  • Permanent saturation test in water at 70 °C (158 °F) and -20° C (-4 °F), studying the behaviour of plastic materials in relation to maximum water absorption

OPV

Our overpressure valves undergo 28 different tests.
The main tests include:

  • Test for springs resistance to salt corrosion

  • Control testing of working strength of springs

  • Control testing of the toughness of the materials in silicone gaskets

  • Dimensional checks on individual components

DSV

Our dry suit valves undergo 181 different tests.
The main tests include,

for DSV Exhaust:


  • Cyclical wear testing of all of the system’s functionalities, rotation/adjustment, manual activation, exhaust and inlet, assessing the wear resistance of the whole system

  • DSV Exhaust tensile-strength test up to 20 kg, measuring resistance to tensile strength in the cap locking system

  • Cyclical testing of the “Pentalever” bending strength (1 million cycles), verifying the wear resistance of the main component and core of the system

  • 18-millibars test, checking the valve sealing system’s efficiency

  • Dump rate test, verifying the dump system’s speed and efficiency (total absence of air in the suit)

  • Dynamic pressure (negative/positive) test, simulating the natural depressurisation that can happen when there is no residual pressure, in order to verify total watertightness in the most critical conditions

  • Permanent saturation test in water at 70 °C (158 °F) and -20° C (-4 °F), studying the behaviour of plastic materials in relation to maximum water absorption

  • 100% underwater product test;



for DSV Inlet:



  • Cyclical wear testing of all of the system’s functionalities, assessing the wear resistance of the whole system

  • Tensile strength test up to 50 kg, measuring resistance to tensile strength in the valve body locking system when the DSV hose is connected

  • Test for resistance to pressure at 20 and at 30 bars, testing the system’s functionality and demonstrating there is no free flow, in compliance with legal requirements

  • Flow test, measures the system’s flow

  • Permanent saturation test in water at 70 °C (158 °F) and -20° C (-4 °F), studying the behaviour of plastic materials in relation to maximum water absorption

  • 100% underwater product test.

LP and HP hoses

Our hoses undergo 161 different tests.
The main tests include,

for LP Hoses:

  • Flow check, verifying the devices’ flow rates

  • Tensile strength test, evaluating resistance to tensile strength in compliance with legal requirements

  • Internal kinking test, to ensure efficient flow in the event of an accidental knot forming

  • 100% underwater product test;



for HP Hoses:


  • Flow check, verifying the devices’ flow rates

  • Tensile strength test, evaluating resistance to tensile strength in compliance with legal requirements

  • Hydrostatic test at 600 bars, ensuring the pressure tightness of the fittings complies with legal requirements

  • 100% underwater product test.
