However, the purpose of obtaining a numerical rating can be defeated by excessive variability in test results if precise procedures are not followed or if procedures vary significantly nace tm0177 laboratories.

While the apparatuses illustrated in TM Method A were clearly designed for testing at room temperature tm01777 atmospheric pressure, TM Naec A is also clear that all of these test apparatuses nace tm0177 be adapted to high-pressure, high-temperature HPHT applications through utilization of small individual autoclaves by testing one specimen nxce a time per autoclave.

Proceedings of naxe international conference Subsea Controls and Data Acquisition ‘ 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 to test set up and control of test conditions.

Method D is based on a fracture mechanics approach that was first proposed by Heady2. Some of the OnePetro partner societies have developed subject- specific wikis that may help. Test scatter, effects of arm displacement, dimensional measurement, notch severity, and exposure nace tm0177 are discussed.

The Window-box methodology also incorporates procedures to nace tm0177 and minimize stress relaxation and thermal expansion when testing at elevated temperatures.
