ISO/PAS 12835:2013旨在评估套管连接的现场应用，在这些应用中，套管连接系统的设计基于应变，主要轴向载荷由受约束的热膨胀驱动，并且主要载荷超过套管连接系统的屈服包络线。因此，ISO/PAS 12835:2013应被视为对ISO 13679的补充协议，ISO 13679适用于经典弹性设计应用。ISO/PAS 12835:2013描述了热井套管连接评估协议（TWCCEP）的结构，并为新用户或重复使用TWCCEP的用户提供了指南，这些用户对TWCCEP规定的熟悉程度可能会有所不同。第6条描述了TWCCEP中采用的基本假设。

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 13679, which applies to classic elastic-design applications.ISO/PAS 12835:2013 describes the structure of the Thermal Well Casing Connection Evaluation Protocol (TWCCEP) and provides guidelines for its use by new or repeat TWCCEP users, whose familiarity with the TWCCEP provisions might vary. Clause 6 describes fundamental assumptions adopted in the TWCCEP.
