Suitable LPG pumps

Accessing the standards is easy: just enter the standard number into an internet search engine and the retail outlet for those standards will appear towards the top of the hit list. Just follow-on with either a credit card number or the organisation's purchase order procedure. Job done.

What is more abstruse is the possibility that the organisation does not have these standards to hand already and this makes one wonder how the installation has been carried out in the past, as successful previous installations can be reasonably cloned to some extent whilst applying the current standards. If no standard is applicable, one wonders what the safe observation distance is...

Amen, Slack, Amen....
