Standards Committees

As the International Standards Organization (ISO) secretariat for Technical Committee (TC 131) – Fluid power, NFPA coordinates standardization work, both internationally at the ISO level and nationally at the technical advisory group level, in the following areas of activity. Participants are welcome to work on as many committees, or as few, as they wish.

These committees typically meet face-to-face two or three times each year, but they also conduct business via conference calls and on-line meetings. Committee members view and download documents and reply to ballots via the Internet by logging onto on-line committee forums.
