ASTM D-120 has been updated to version “-14a”, approved Nov 1, 2014 and effective December 2014.
ASTM D-120-14a, Standard Specification for Rubber Insulating Gloves
The update changes the wording of Section 220.127.116.11 to allow for electrical testing of gloves to be performed using either a true-“RMS or average responding” voltmeter. The previous edition wording used antiquated language of “RMS responding voltmeter”, and was found to confuse users of the standard.
