The determination of pedal data or verification of guarantees that are outside the scope of this Code shall be made only with the written agreement of the parties to the test. The agreed methods of measurement and computation shall be defined in writing and fully described in the test report.
1-3 UNCERTAINTY
The explicit measurement methods and procedures have been developed to provide a test of the highest level of accuracy consistent with practical limitations for acceptance testing. Any departure from Code requirements could introduce additional uncertainty beyond that considered acceptable to meet the objectives of the Code.
The application of uncertainties to adjust test results is not part of this Code; the test results themselves provide the best indication of actual performance. The uncertainty is used to determine the quality of the test and reflects the accuracy of the test instrumentation and stability of the test conditions. Test tolerance, margin, and allowance arc commercial matters that arc not addressed by this Code.
The maximum uncertainties shown below are limits — not targets. A Code precept is to desigu a test for the highest practical level of accuracy based on current engineering knowledge. For a commercial test, this philosophy is in the best interest of all parties to the test. Deviations from the methods stated in this Code are acceptable only if it can be demonstrated to the test parties that the deviations provide equal or lower uncertainty in the calculated test result.
A pretest uncertainty analysis shall be performed to establish the expected level of uncertainties for the test, including an estimate of the random (precision) uncertaintv based on experience.
A post-test uncertainty analysis is similarly required. The results of a thermal performance test, conducted in full compliance with the procedures and instrumentation specified in this Code, shall be considered valid if the cakulated overall uncertainty in the thermal capability is less than ±4.0%. If the post-test uncertainty is greater than ±4.0%, then the test is not a Code test. In addition, the uncertainty of Code tests that determine the condensate temperature shall be less than ±03°C and Code tests that measure the dissolved oxygen in the condensate shall have an uncertainty of less than ±2.6 ppb.
