Overview

Hydrogen is the easy part. Proving the components is the work.

A hydrogen vehicle lives or dies by parts you can hold in one hand — regulators, valves, injectors, relief devices, lines and fittings. Before any of them is allowed near a road, a standard demands proof: tens of thousands of pressure cycles, burst margins, leak rates counted in cubic centimetres per hour, cold hydrogen, hot chambers, corrosion and time. This facility exists to produce that proof.

Fig · 02 The duty — components on test behind blast-rated steel (representative render)

The system is a complete certification workshop for compressed-hydrogen fuel-system components, under contract for a Government of India automotive testing & certification centre through an Indian heavy-engineering public-sector enterprise. Its scope is the full mandatory test matrix of ISO 12619 (Parts 1–16), UN ECE R134 and AIS 157 — eleven test methods applied across fifteen component families, from pressure regulators and cylinder valves to TPRDs, excess flow valves, hoses, rigid and flexible fuel lines, filters, fittings and HFCV (hydrogen fuel-cell vehicle) components.

The numbers set the architecture. Hydrostatic strength and burst proofs run to 3500 bar from a hydraulic intensifier; gaseous hydrogen service spans sub-atmospheric to 1050 bar from a compressor and booster station; hydrogen arrives at the device under test (DUT) at temperatures down to −40 °C, matching the fuelling protocol; and blends from 5% hydrogen in nitrogen or helium are mixed automatically to within 1% of full scale. Nine blast-rated chambers run their tests independently, so a 50,000-cycle endurance on one DUT never holds up a burst test on another.

A certification lab cannot argue with its own data. Everything this facility produces — every bar, every cycle, every leak rate — is signed, timestamped and traceable. That is the product.

Under Contract · In Execution

A won programme, being built

The facility is under contract following open national competition, with detailed engineering in progress at Neometrix Noida — test-requirement matrices at controlled revision, the electrical design basis issued, and long-lead gas-train packages in procurement.

Standards-Led · By Design

The standard is the specification

Every rig parameter traces to a clause: cycle counts, pressure ratios, temperature ladders and leak limits come straight from ISO 12619, UN ECE R134 and AIS 157 — and where documents differ, the contract resolves the gap in favour of the test standards.

Closed Loop · Gas Economics

Hydrogen is recovered, not vented

A closed-loop recovery and recycling train returns test gas to service instead of venting it, with three skid-mounted make-up cylinders (hydrogen and two certified blends) covering the balance — testing economics a working certification lab can sustain.

Architecture

A gas train, a test floor, and a paper trail that survives audit.

The diagram below is the facility’s process architecture as the engineering defines it — the closed-loop gas train, the nine-chamber test floor, the separate 3500-bar hydrostatic branch, and the safety and data systems wrapped around them.

FIG · 03PROCESS ARCHITECTURE · CLOSED-LOOP GAS TRAIN · NINE-CHAMBER FLOOR

Fig · 03 From make-up cylinders through blending, compression and pre-cooling to nine independent chambers — and back through recovery

Arc · 01

The Gas Train

Three skid-mounted make-up cylinders — hydrogen, hydrogen-nitrogen and hydrogen-helium blends, each ≥50 L at ≥200 bar with a certificate of analysis — feed an automatic blending skid that holds mixture accuracy within 1% of full scale at supply pressure, then a compressor and booster station that regulates gaseous test pressure from sub-atmospheric to 1050 bar. A pre-cooling stage delivers hydrogen at the DUT down to −40 °C; and a dedicated nitrogen purge system with its own lines, valves and vents inerts any circuit before hands touch it.

Arc · 02

The Test Floor

Nine chambers — blast-rated, gas-tight, stainless-steel — each with independent control and monitoring, so nine devices under test run nine different programmes at once. One of the nine is a dedicated burst bay on the hydraulic branch; around them sit the specialist rigs the matrix demands: a pneumatic-strength bench, a slow-strain-rate stress-corrosion-cracking rig in a hydrogen atmosphere, extreme-temperature pressure-cycling from −40 to +85 °C, and permeability measurement cells for hoses and lines.

Arc · 03

The 3500-Bar Branch

Burst and hydrostatic proofs are hydraulic, not pneumatic — a deliberate piece of physics, since liquid stores a fraction of the energy of gas at the same pressure. A hydraulic intensifier generates up to 3500 bar with programmable ramps (the standards ask for rates up to 1.4 MPa/s and holds of three minutes or more), drives components to 2.5× — and for flexible lines and fittings 4× — working pressure, and records the burst event at high speed for the certificate.

Arc · 04

Safety & Data

Electricals in classified zones are ATEX/IECEx; sixteen-point hydrogen detection, fan-proven dilution keeping any release below 25% of the lower explosive limit, blast-relief panels, vent stacks with flame arrestors, nitrogen purging and a hardwired emergency shutdown follow NFPA 2 and PESO practice under a HAZOP-led safety case. The PLC/SCADA layer runs every station through distributed I/O and produces timestamped, digitally signed records — archived for ten years.

FAQ

Common questions.

Plain-language answers from the engineering team.

Q · 01 How is this different from a hydrogen cylinder burst chamber or a leak test rig?

Scope, and what the result is for. Our burst chamber for hydrogen cylinder testing destroys storage cylinders; our dynamic high-pressure hydrogen leak test rig answers one question — does it leak — about vessels and assemblies. This facility is a different class of machine: a complete certification workshop for the small components of the fuel system itself, running all eleven mandatory methods of ISO 12619, UN ECE R134 and AIS 157 — from endurance cycling and burst to permeability and stress corrosion — because a type-approval file needs every one of those numbers, not just one.

Q · 02 How do ISO 12619, UN ECE R134 and AIS 157 relate to each other?

They are three views of the same physics. ISO 12619 is the component standard — sixteen parts: general requirements and shared test methods up front, then a part per component family, each defining its own test set and limits. UN ECE R134 is the international vehicle regulation for hydrogen safety, which references component-level proofs from the vehicle side. AIS 157 is India’s automotive industry standard implementing those requirements nationally. A component headed for an Indian hydrogen vehicle must satisfy all three — which is why the facility’s method matrix maps every test to its clause in each document, and why the contract resolves any conflict in favour of the standards themselves.

Q · 03 Why 3500 bar hydraulic but 1050 bar gaseous?

Stored energy. A litre of water at 3500 bar holds a small fraction of the energy of a litre of gas at the same pressure, because liquids barely compress — so the standards deliberately prescribe hydraulic media for strength and burst proofs, and the facility generates its highest pressures with a hydraulic intensifier behind a blast-rated bay. Gas is reserved for the duties that need real hydrogen physics — leakage, permeation, embrittlement, cold-fuelling exposure — where 1050 bar covers the service and proof conditions of 700-bar-class vehicle systems. Same components, two disciplines, each doing the dangerous thing the safer way.

Q · 04 What does the hydrogen safety case involve?

Layers, each assuming the one before it fails. Electricals in classified zones are ATEX/IECEx-rated so equipment cannot become an ignition source. Sixteen hydrogen detection points watch for any release; ventilation is fan-proven and sized to dilute a release below 25% of the lower explosive limit before it matters. Blast-relief panels, vent stacks with flame arrestors and nitrogen purge systems manage energy and inerting; an emergency shutdown chain closes fail-safe valves on detection, fan failure or a pressed button. The whole arrangement follows NFPA 2 and PESO practice and is developed through a formal HAZOP into a safety case — with the more stringent requirement prevailing wherever documents differ.

Q · 05 Do nitrogen or helium blends substitute for testing with real hydrogen?

No — and honest measurement is exactly why the facility does both. Inert blends make many duties safer and cheaper to run, and ISO 12619-2 permits them for leak measurement provided the result is converted to a 100% hydrogen equivalent, which is how the facility reports every blend-based leak rate. But some questions only hydrogen answers: embrittlement, permeation through hose walls, cold-fuelling exposure at −40 °C. So the gas train supplies both — certified blends from 5% hydrogen upward, mixed to within 1% of full scale, and 100% hydrogen up to 1050 bar — and the test method, not convenience, decides which one flows.

Q · 06 What makes test data “certification-grade”?

Traceability at every link. Instruments are calibrated with NABL / ISO 17025-traceable certificates before a single reading counts. Every record the SCADA produces is timestamped and digitally signed at source, so a cycle count or burst pressure cannot be quietly edited afterwards; reports export to PDF, Excel and CSV with the raw data archived for at least ten years; and access is role-based, so who did what is part of the record. The facility’s acceptance route is built the same way — factory acceptance at our works, then site acceptance demonstrating all eleven methods — because a certificate is only as strong as the audit trail behind it.
