Rationale

BALLOT-Inclusion of Practice E29. Current standard is not clear on handling significant digits. As an example, the water vapor sorption has a maximum value of 5.0 in the primary table. It is not currently stated in this standard if a tested result of 5.04 would round down to 5.0 thus meeting the requirement or if the value of 5.0 is absolute meaning any value above 5.0 is not passing. Addition of text would make the above value of 5.04 non-compliant as it is above 5.0. Only the proposed changes within Sections 1 and 2 are open to ballot. No other sections are open for ballot.
