The Standard-Specific Interest Groups (SSIGs) for the following standards are in need of additional members. These groups may or may not have ballots currently open.
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:
SSIGs that need 1 member:
T 252 pH and electrical conductivity of hot water extracts of pulp, paper, and paperboard
T 255 Water-soluble sulfates in pulp and paper
T 256 Water-soluble chlorides in pulp and paper
T 272 Forming handsheets for reflectance testing of pulp (sheet machine procedure)
T 406 Reducible sulfur in paper and paperboard
T 434 Acid-soluble iron in paper
T 438 Zinc and cadmium in paper
T 504 Glue in paper (qualitative & quantitative determination)
T 545 Cross-machine grammage profile measurement (gravimetric method)
T 578 Accelerated light aging of printing and writing paper by xenon-arc exposure apparatus
T 602 Analysis of sulfuric acid
T 613 Analysis of caustic soda
T 619 Analysis of salt cake
T 632 Analysis of sodium silicate
T 692 Determination of suspended solids in kraft green and white liquors
T 1217 Photometric linearity of optical properties instruments
T 1218 Calibration of reflectance standards for hemispherical geometry
SSIGs that need 2 members:
T 493 Identification and determination of melamine resin in paper
T 572 Accelerated pollutant aging of printing and writing paper by pollution chamber exposure apparatus (needs 2 more members with interest categories different from General Interest)
T 621 Analysis of rosin
T 622 Analysis of sodium hydrosulfite
T 628 Analysis of rosin size
SSIGs that need 3 members:
T 245 Silicates and silica in pulp (wet ash method)
T 421 Qualitative (including optical microscopic) analysis of mineral filler and mineral coating of paper
T 611 Analysis of bleaching powder, calcium hypochlorite bleach liquor and bleach sludge
SSIGs that need 4 or more members:
T 495 Bending number of paperboard
T 656 Measuring, sampling, and analyzing white waters
SSIGs that have the minimum amount of members but are inviting new members to join
T 836 Bending stiffness, four point method
Participating in a SSIG is free and open to any industry expert interested. Join now!
If no progress is made on balancing these SSIGs, then the respective methods may be considered for withdrawal at the next Q&SMC meeting. If you have an interest in becoming a member of either of these SSIGs please contact standards@tappi.org
