Following on from an earlier thread - this was indeed in the Info Brief from the PGDB in April.  To summarise (direct from the Info Brief):

Proprietary pipe systems are one are that have significant changes with the installation of a pipe system.  Key points to note:
The requirement to follow manufacturer's instructions
The requirement to provide a label at the point of supply and
the provision for a reversion fitting or a transition connection

Manufacturers carry out tests to ensure products meet the stands to be used in NZ.  Each manufacturer can have different installation requirements - UV protection is a good example.  Here, instructions must be followed as the manufacturer states.  (NB - following manufacturer's instructions does not relieve the obligation to meet the requirements of Section 2 of the Standard).

As some proprietary pipe systems look alike, it is difficult to tell the difference between systems - particularly after the installation has been there for some time.  Unless state otherwise, no other systems fittings or tooling can be used on their system.  Identifying the system is a key inclusion in the standard.

AS/NZS5601.1 point 4.5.4 states a manufacturer label shall be attached adjacent to the gas meter or LP gas cylinder(s).

Transition connections to proprietary systems or reversion fittings allow for the connection of different pipe systems.  If different piping systems are being used it is important to identify clearly which system is installed in what part of the installation.

For installations in a caravan, AS/NZS5601.2  2.6.2 states:  Proprietary systems shall be suitable for their intended use and shall be installed as a complete entity in accordance with the manufacturer's relevant instructions.  Multi layer proprietary  piping systems shall not be used in mobile applications.

It is important with any gasfitting work you carry out that you are familiar with the means of compliance you are using.  You need to ensure the installation is safe and the work you carry out is compliant before turning on the gas supply and issuing a compliance certificate.

End of item.

So - after investigation into costs of these metal labels - IPLEX K1 tags are retailing at $25 + GST EACH at Mico.  Your cost will depend on your discount structure, but it also seems to me that these tags are doing a bit of advertising for IPLEX and K1 and should cost significantly less, or come free when you buy the pipe or fittings.

For those of you that haven't seen one of these tags (and you could make your own labels, but they would need to be waterproof) - what they have to have on them is:

Parts of this installation contact the XXXXXXXXXXXXXXXXXX system.

Installed by:  _________________________________
Licence No:___________________________________
Date:  _______________________________________
Capped Tee location: ___________________________


The IPLEX one says:
This home is plumbed with iPlex K1Gas pipe and fittings system for gas.
A threaded connectgor for future extension is located: _________________________________________
Gasfitters name: _______________________________________________________________________
Gas licence number: ____________________________________________________________________
Contact iPlex on 0800 800 262

This will add $25 per job on to the consumer, or make you own and make it cheaper.  A good idea, but any manufacturer of gas pipe and fittings that decides to make the labels available free of charge will get a lot of business.

How many of you are doing this now?

jaxcat, have you seen any of the copper tube manufactures produce these tags ?

Copper won't come under "proprietary"  pipe systems - relates basically to pex.  Although it is an interesting point.  Our supplier is taking the issue up with the pipe manufacturer that we purchase off basically saying they should come with the pipe - it is necessary now - otherwise we'll be making our own - we won't be paying $12 odd for them.

Here is a curve ball for you! why isnt ALL plumbing pipe systems not having to be identified???

why risk or put yourself though it , i only use copper ever on gas

I only know IPLEX have produced them for K1 - not sure about other multi layered pipe systems - but the PGDB newsletters shows what is required if you make your own labels.  I agree this would be a better upskilling item.  Still you can claim the time it's taken to read this forum and the PGDB article as self directed learning - got to be worth at least 2 points don't you think.  If your big name supplier is Mico then they are selling the Iplex labels - although it would appear not all branches know about it.
As far as Plumbing World goes I wouldn't have a clue.

From some questions I asked today, it would appear that only IPLEX have produced the labels - and it was because they were approached to do so (not sure if from the regulator).  So it doesn't look like the other piping systems are geared up at all.  Knowledge on this is sparse, although it was in the Info Brief from the PGDB.  We have fitted a few - but I was choking at the cost of what is essentially a label.  I think we will produce our own going forward and use them as a marketing tool.    So I guess big ups to Mico for being on board early!

I don't agree mini g - I think the manufacturer of the pipe has to state that it is interchangeable with another pipe system - see below from the Info brief
