1. Rationale
An error was discovered in ASTM D4637-12 within TABLE 1 under Water absorption, max, mass % for Type III. The requirement is currently listed at +/-8, -2A and should be +8, -2A. For Type I and Type II the numbers are correct for water absorption within Table 1. The task group chairperson requests an affirmative vote on this issue so that this error can be rectified.
