[GRAPHIC] [TIFF OMITTED] TR07MR11.116
Or,
(B) The lower 95 percent confidence limit (LCL) of the true mean divided by 0.90, where:[GRAPHIC] [TIFF OMITTED] TR02MY11.081
(b) Certification reports. (1) The requirements of Sec. 429.12 are applicable to illuminated exit signs; and
(1) The requirements of Sec. 429.12 are applicable to illuminated exit signs; and
(2) Pursuant to Sec. 429.12(b)(13), a certification report shall include the following public product-specific information: The input power demand in watts (W) and the number of faces. [76 FR 12451, Mar. 7, 2011; 76 FR 24778, May 2, 2011]
