## What the source says

> 51926,PAS,,ISO/PAS 12835:2013,Qualification of casing connections for thermal wells,Qualification des raccordements de boîtiers pour les puits thermiques,2013-12-12,1,"['75.200','75.180.10']",ISO/TC 67/SC 5,9599,,[75966],['en'],142,"<p>ISO/PAS 12835:2013 is intended for assessment of casing connections for those field applications in which the design of the casing-connection system is strain-based, and in which primary axial loading is on the casing-connection system driven by constrained thermal expansion, and in which that primary loading exceeds the casing-connection system's yield envelope. Consequently, ISO/PAS 12835:2013 should be considered as a protocol that is complementary to ISO 1
