Cylinder Hydrostatic Testing Course (Part 2)

Professional Hydrostatic Testing Training | CPD Aligned

The ASSET Cylinder Hydrostatic Testing Course (Part 2) is a focused, practical programme for technicians who want to move beyond visual inspection and carry out full pressure testing of cylinders properly and confidently.

This course builds directly on Cylinder Visual Inspection (Part 1) and is designed for those who are already working with cylinders and want to take the next step into testing, certification, and decision-making.

About the Course

Hydrostatic testing isn’t just about using the machine.
It’s about understanding what the cylinder is doing under pressure — and knowing how to interpret the results correctly.

Over two days, you’ll work through both the theory and the practical side of testing, including how to identify failure, how to apply limits, and how to make decisions you can stand behind.

The aim is simple:
To give you the confidence to carry out testing properly, consistently, and in line with recognised standards.

Course Structure

• Duration: 2 Days
• Theory + Practical Combined
• Hands-on workshop assessments included

This is a practical course. You will be working with real equipment, not just learning from slides.

Who This Course Is For

• Technicians who have completed Cylinder Visual Inspection (Part 1)
• Dive Industry Technician Course (DITC) students
• Cylinder inspectors looking to move into testing
• Dive centres wanting in-house testing capability

This is not an entry-level course — it is for those already involved in inspection work.

What You’ll Cover

• Hydrostatic testing procedures and setup
• Understanding expansion (elastic vs permanent)
• Interpreting test results and limits
• Principles of metallurgy and how materials behave under pressure
• Crack detection methods, including eddy current awareness
• Identifying failure conditions and condemnation criteria
• Recording results and maintaining traceable documentation

Everything is taught with a focus on real decisions in real working environments.

Standards & Compliance

This course is aligned with recognised inspection and testing practices, including:

• ISO 18119 (current requirements and updates)
• EN / BS standards
• CGA guidance where applicable

There is increasing emphasis across Europe on “competent and approved” testers.
This course helps ensure you meet those expectations — not just in theory, but in practice.

Why This Course Matters

Hydrostatic testing is where decisions are made.

• Does the cylinder pass?
• Does it fail?
• Is it safe to return to service?

These decisions carry real responsibility.

This course gives you:

• The understanding behind the numbers
• The ability to recognise problems early
• The confidence to make the right call

Key Benefits

• Hands-on hydrostatic testing experience
• Clear understanding of expansion limits and failure criteria
• Practical insight into metallurgy and material behaviour
• Introduction to crack detection methods
• Training aligned with recognised international standards
• Supports professional, defensible decision-making

Certification

On successful completion, you will receive:

ASSET Cylinder Hydrostatic Testing Certificate

This confirms that you have completed structured training and can carry out hydrostatic testing in a professional working environment.

What’s Included

• Full training manual (printed copy required)
• Academic instruction and workshop training
• ASSET hydrostatic course handbook
• Certification

Flexible Learning Option

If you complete the academic component online and pass the assessment, you can attend the practical training later — up to 12 months after completion.

You also have the option to revisit the theory in a classroom setting if needed.

A Practical, Straightforward Approach

This course avoids unnecessary complexity.

You will not be taught “black art” techniques or shortcuts.
You will learn how to test cylinders properly, safely, and in line with recognised practice.
