What Does ASHRAE Expect from SSPC 41?
 ASHRAE Standards Action bulletin (Volume 1, Issue 23) dated October 7, 2005 contained the following announcement: "The new Standing Standards Project Committee, SSPC 41, Standard Methods for Measurement, was approved with the charge to be the consensus body for standard methods for measurement of liquids and gases in HVAC&R applications and to maintain and revise each of the 41-series individual standards."
 

How Will SSPC 41 Operate?
SSPC 41 will be comprised of a project committee that serves the overarching interests of the nine subcommittees – one subcommittee for each of the separate 41-series standards as noted in the table below. Voting membership in the SSPC 41 project committee will be structured to:
* Continuously meet the ASHRAE/ANSI balance requirements (Producers, Users, and General Interest individuals),
* Appropriately and fairly represent the interests of the three cognizant TCs (TC 1.2 lead, TC 1.1, and TC 8.1), and
* Appropriately and fairly represent the interests of the various separate 41-series subcommittees.
Specifically, the SSPC 41 project committee:
* Recommends approval of proposals for changing 41-series standards
* Recommends draft standards for public review and subsequent publication
* Recommends approval of responses to public review comments
* Recommends approval of proposed changes in Title, Purpose, and Scope
* Recommends approval of requests for interpretation
* Recommends appointment of a specific Vice Chair annually
* Communicates status and changes to all stakeholders (cognizant TCs, SPLS, and all project committee members)
 

How Will SSPC 41 Change the Way We Revise the Separate 41-series Standards?
SSPC 41 does not alter the membership composition of the committees needed to revise any of the 41-series standards. The work of revising any 41-series standard will now be done by an SSPC subcommittee (instead of a separate SPC) with a Subcommittee Chair (just like a separate SPC Chair) who will lead the subcommittee through the revisions of the standard. Each subcommittee will be comprised of individuals with relevant knowledge (just like a separate SPC). Each existing 41-series SPC member will be automatically rolled over into the corresponding SSPC Subcommittee.
