9、he applicable tabular value by 0.08 in H2O 20 Pa. 4) If the manufacturers rated external static pressure is less than 0.10 in H2O (25 Pa), then the indoor unit should be tested at that rated external static pressure. (See Section 5.2.1.2) 5) See Definition 1.35 of Appendix C to determine if the equi

10、pment qualifies as a Small-duct, High-velocity System. 6.6 Test Tolerances (Applies to all products covered by this standard). To comply with this standard, measured test results shall not be less than 95% of Published Ratings for capacities, SEER, HSPF, EER values, and COP values and not less than

11、90%of Published Ratings for IEER and SCHE values. 6.6 Verification Testing Uncertainty. When verifying the ratings by testing a sample unit, there are uncertainties that must be considered. Verification tests, including tests conducted for the AHRI certification program shall be conducted in a labor

12、atory that meets the requirements referenced in this standard and ASHRAE Standard 37 and must demonstrate performance with an allowance for uncertainty. The following make up the uncertainty for products covered by this standard. 6.6.1 Uncertainty of Measurement. When testing a unit, there are varia

13、tions that result from instrumentation and measurements of temperatures, pressure, and flow rates. 6.6.2 Uncertainty of Test Rooms. A unit tested in multiple rooms will not yield the same performance due to setup variations. 6.6.3 Variation due to Manufacturing. During the manufacturing of units, th

14、ere are variations due to manufacturing production tolerances that will impact the performance of a unit. 6.6.4 Uncertainty of Performance Simulation Tools. Due to the large complexity of options, use of performance prediction tools like an AEDM has some uncertainties. 6.7 To comply with this standa

15、rd, verification tests shall meet the performance metrics shown in Table 13 with an uncertainty allowance not greater than the following: Table 13.
