Historical Standard: Standard Guide for Designing and Conducting Visual Experiments<\/h4>\n
\n

ASTM E1808<\/h4>\n

Scope<\/strong><\/p>\n

\n

1.1<\/span> This guide is intended to help the user decide on the type of viewing conditions, visual scaling methods, and analysis that should be used to obtain reliable visual data.<\/p>\n<\/p><\/div>\n

\n

1.2<\/span> This guide is intended to illustrate the techniques that lead to visual observations that can be correlated with objective instrumental measurements of appearance attributes of objects. The establishment of both parts of such correlations is an objective of Committee E12.<\/p>\n<\/p><\/div>\n

\n

1.3<\/span> Among ASTM standards making use of visual observations are Practices D1535<\/span>, D1729<\/span>, D3134<\/span>, D4086<\/span>, and E1478<\/span>; Test Methods D2616<\/span>, D3928<\/span>, and D4449<\/span>; and Guide E1499<\/span>.<\/p>\n<\/p><\/div>\n

\n

1.4<\/span> This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.<\/i><\/p>\n<\/p><\/div>\n
