This standard G 493-2 encompasses personal and professional
requirements for companies providing maintenance for gas plants and
installations that fall within the scope of DVGW G 495 (A), as well as biogas
injection and refeeding plants as specified by DVGW G 265-2 or hydrogen
injection plants as specified by DVGW G 265-4 (M).Companies which, within the
context of comprehensive plant management, either as original operators or as
contractors, are responsible for the maintenance of energy plants, and possess
the required personal qualification and organization according to DVGW G 1000
(A), may conduct the maintenance of gas plants without certification as defined
by this standard within the network which they have the abovementioned
responsibility for. The prerequisite for the maintenance without certification
as mentioned above is that the expert and tech-nical conditions detailed in
this standard are met by the company’s own workforce or by service providers
with a TSM certification or other corresponding certifications. The company
shall appoint the experts re-sponsible for maintenance in writing. The
fulfilment of these conditions can be verified e.g. during a TSM review
