WebBBR; PG Verification with MP1a Analysis. Same as PG verification with the addition of the Direct Tension test and the BBR at two temperatures. This combination of tests provides a more in-depth low temperature property analysis. Direct tension data is incorporated with that of the BBR to determine compliance with critical cracking requirements. WebDec 24, 2014 · Operated at room temperature, this shield enables specification of the BBR environment to a corresponding fractional clock uncertainty contribution of 5.5×10−19. Combined with uncertainty in the atomic response, the total uncertainty of the BBR Stark shift is now 1×10−18.
