    Rationale

    The rationale for the ballot item to revise Test Method C42/C42M-18a section 7.7 to allow either of the C1542/C1542M methods (jaw caliper or ruler) to be used for determining the average core length. All three length measurement methods have the same reporting requirements as C42/C42M-18a.
