A number in parentheses indicates the year of last reapproval. Remove only as many specimens as can be rated within the speci? The post-recovery rating allows evaluation of the permanent effects of the exposure as distinct from the transient effects, and is especially important for evaluation of color and gloss.

Although the apparatus and procedure could be employed in immersion tests using solutions of various materials in water, this practice is limited to tests in water alone. Users of this standard are expressly advised that determination of the validity of any such d87 rights, and the risk of infringement d8770 such rights, are entirely their own responsibility.
