We have no amendments or corrections for this standard. The results of tests conducted for less than 12 months will depend on the particular season of the year in which they begin. Specimen marking shall be in accordance with Practice G and shall be such that there is no interference with either the exposure or the subsequent testing.

NOTE 6—Sand as a ground cover may be desirable where the abrasive astn of exposure to wind-blown sand is a part of the desired exposure. This method of mounting is shown in C1435.
