    A close review by the Task Group on D7430 revealed that there were still some remaining inconsistencies in the document left over from the time that the four old standards of D4702, D4916, D6518 and D7256 were combined into this one single standard. This is the first in a series of ballots addressing changes driven by cleaning up the usage of SI and Non-SI (inch-pound) units within the standard. This ballot is solely to change the title of the Standard to D7430/D7430M (see above). All proposed changes are presented using red font for additions. This is necessary because all four parts of the standard contain the following statement in the scope. The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
