Work Item
ASTM WK97319

Revision of C430-25 Standard Test Method for Fineness of Hydraulic Cement by the 45-µm (No. 325) Sieve

Rationale

The current wording in the standard does not allow for a digital gage. Newer gages are typically digital and more readable than analog gages. The traditional gage requirements are being kept the same here so as to not invalidate existing equipment.
