SSIG Members Needed
All Standard-Specific Interest Groups (SSIG) require a minimum of 10 members in order to ballot and vote on a draft of a method. The following test methods do not have the required minimum number of member to initiate a ballot:
If no progress is made on balancing these SSIGs, then the respective methods may be considered for withdrawal at the next QSMC meeting. If you have an interest in becoming a member of either of these SSIGs please contact standards@tappi.org.
