NOTES:	1.	See Section 315.Tables D & E for limiting apertures (see ANSI Z136.1 pg. 44).
	2.	For multiple pulses, apply correction factor Cp given in Section 315.Table C.
	3.	For information on correction factors T1, CB, CA, Cp and Cc, see Section 315.Table C.

NOTES:	1.	See Section 315.Tables D & E for limiting apertures (see ANSI Z136.1 pg. 44).
2.	For multiple pulses, apply correction factor Cp given in Section 315.Table C.

GENERAL NOTES:	1.	The MPE for diffuse reflections at wave lengths between 0.400 and 1.400µm is obtained by multiplying the corresponding MPEs above by CE (see Section 315.Table C for correction factors and T1).
2.	For repeated (pulsed) exposures, see ANSI Z136.1.
3.	For purposes of this Section 315.Table A, the following abbreviations or symbols are used:
			µm	=	micrometers
			ts	=	time in seconds
			J	=	joules
			W	=	watts
			cm	=	centimeters
