INTRODUCTION
For any gas installation inside a residential building, the various parties involved (developer, architect, design office, installer, gas distributor, inspection office, etc.) must take into account the regulatory context associated with gas energy.
In most cases, all they have to do is apply the regulations, which provide a clear and precise answer to the problem at hand.
On the other hand, solving a particular problem may require interpretation. Interpretation is always a tricky business, and it's important to make sure that everyone involved is on the same wavelength.
Your contacts for technical and regulatory questions concerning gas are :
Application technicians (ATA) from regional residential and tertiary gas agencies and/or EDF GDF SERVICES centers;
the "Technical and regulatory information" engineers at CeGIBAT (Gaz de France's information center for industry and construction).

DTU composition
The DTUs are mainly :
technical specifications (CCT), originally known as "cahiers des charges", which set out the technical conditions to be met by contractors in selecting and using materials for the various trades;
calculation rules that enable structures to be sized according to operating conditions or construction sites;
...
Composition of ATG specifications
The characteristics of tubes, fittings and filler alloys, as well as assembly conditions, are defined in ATG specifications:
B. 521 : Steel tubes and fittings - Filler alloys ;
B. 524: Copper tubes - Fittings - Means of assembly - Filler alloys.
Each specification has several parts....
