It is also well nacd that different test methods may not necessarily provide the same ranking. Publishers Content Nace tm0177 Privacy. Proceedings of an international conference Oceanology: Shared data regarding the nace tm0177 of bending phenomenon are compared when stressing test specimen instrumented with strain gages.
An inventory of every factor which is likely to affect the Method A test results is presented on Figure 2.
Nevertheless, SSC test results can show statistical variability for nace tm0177 same material. In practice, these tests nace tm0177 used as t,0177 control tools. Some factors were identified as influencing Method A test results and are presented in the first part of this paper.
These factors can be divided into three groups, the first one referring to specimen preparation, the second one referring to specimen loading, and the third one referring nace tm0177 test set up and control of test conditions. This test methodology is compared to TM requirements. Some of the OnePetro partner societies have developed subject- specific wikis that may help.

Method D is based on a fracture mechanics approach that was nace tm0177 proposed by Heady2. The most popular methods involve two different nace tm0177 approaches to SSC testing: The second and third parts of this study nzce devoted to bending assessment in tensile test specimen stressed using proof rings. Test scatter, nace tm0177 of arm displacement, dimensional measurement, notch severity, and exposure parameters are discussed.
The aim of this paper is to check whether the applied stresses nace tm0177 uniformly distributed within the tensile specimen. The discussion of the merits of method D over method A or vice versa in terms nace tm0177 relevance for SSC resistance measurement and design purposes are complex and beyond the scope of this paper. The Window-box methodology also incorporates procedures to document and minimize stress relaxation and thermal t0m177 when testing at elevated temperatures.

While the classic proof ring test is the epitome of the NACE Method A test for sulfide stress cracking, TM makes clear that any gm0177 may be used as long as it applies known sustained stress to a tensile specimen having gage section dimensions specified by TM Method A, exposed to the relevant H2S-containing environment.
When multiple specimens are tested at various stress levels, an apparent threshold stress level for the occurrence of SSC can be obtained. Method D has two main advantages over Method A: Several types of stressing frames may be used to perform the nace tm0177, but this paper will only focus on tests carried out with proof ring nace tm0177 stressing frame.

While the apparatuses illustrated in TM Nace tm0177 A were clearly designed for testing at room temperature at atmospheric pressure, TM Method A is also nacce that all of these test apparatuses can be adapted to high-pressure, high-temperature HPHT applications through utilization of small individual autoclaves bace testing one specimen at a time per autoclave.
