This ballot is part of a series of ballots that include eight (8) specifications. ASTM Standards C126, C212, C216, C652, C902, C1088, C1272 and C1405 each have provisions for a viewing distance that detract from appearance. None of these eight (8) standards contain any language specific to the lighting conditions under which they should be viewed (except for C216 which contains some language in the non-mandatory Appendix. The Appendix contains the ambiguous language under normal lighting conditions.). Other masonry standards contain language specific to the lighting conditions under which they should be viewed. For example, ASTM C73, C90, C1634 and C1670 (all under the jurisdiction of C15) each contain mandatory language that includes the words under diffused lighting. Adding under diffuse lighting is appropriate.
