PE technical guidance
HDPE Pipe technical guidance (High quality Polyethylene Pipes)

What training is necessary for operatives to assemble PE pipe networks?

Quick access

All operatives making use of butt fusion and electrofusion jointing systems for PE pipes and fittings should have undergone a training course and, upon passing an exam, be certified as an approved operator and issued with an operator’s badge. In general such training courses and their assessment should comply with the requirements of ISO/TR 19480:2005.

The badge must conform with ISO 12176-3:2001 and in most countries the badge has a validation period of 1 to 2 years after which it must be renewed by repeating the examination or undertaking a shorter refresher course.

A typical badge is shown below. Every fusion operator must carry his badge at all times when undertaking fusion work.

Every fusion operator must carry his badge

In Europe there are several training procedures and codes of practice concerning the training and certification of operators. These include:




ÖVGW W 106: Training and examination of Plastic Tube Fitters – Water

ÖVGW G 0322: Training and examination of Plastic Tube Fitters – Gas


NS 416-2: Operators for welding of PE and PP for pipes and fittings - Part 2: Training schedule


Welding certificate according to requirement of NEN 7200


Courses must comply with ISO/TR 19480:2005
