Afternoon all,

I wonder if anyone can help me?

Considering commercial premises (offices, shops, etc.) above and beyond a minimum of annual gas appliance maintenance - is there a requirement under legislation or guidance for pipework tightness testing?

Have you got a copy of the Gas Safety (Installation and Use) Regs?

Part F Maintenance states in Reg 35 that "it shall be the duty of every employer or self-employed person to ensure that any gas appliance, installation pipework or flue at any place of work under his control is maintained in a safe condition so as to prevent risk of injury to any person".

So yes, pipework is included as part of the gas "installation". Of particular concern is pipework leading to LPG tanks, especially if it's underground.

The recommendation is, as is often the case" a very general one.

I understand as per http://www.globalmaint.co.uk/content/ANKN-6RGH66 that the Institution of Gas Engineers recommends that pipework systems be inspected at least every five years. Can anyone confirm this?

The reason I ask is that you will almost always come across gas appliance maintenance records, but I am yet, in my 6 years in this profession to come across a gas pipework tightness test.

I do love it when a question is asked and no one knows the answer to it! Deathly silence...

For testing our systems ( arange of process gases including natural gas) we use drop testing (seeing if the pressure drops over a period of time) and leak testing with spray bubbly water to check joints.
