    April 2013 ISA Standards Update

    To begin work on updating its current standard, the ISA67.02 subcommittee, Instrument Sensing Line Piping and Tubing Standards for Use in Nuclear Power Plants Standards, met on April 19th via conference call. A productive discussion was held by the ISA67.02 members representing manufacturers, users, and representatives from the US Nuclear Regulatory Commission (NRC). The revisions to ISA-67.02.01, Nuclear Safety-Related Instrument Sensing Line Piping and Tubing Standard for Use in Nuclear Power Plants, will include clarification of existing figures and addition of figures applicable to boiling water reactors (BWRs), as well as addressing concerns of slope of tubing. The revised standard will be reviewed at the next ISA67.02 meeting to be held in conjunction with the 2013 ISA Power Industry Division Symposium in Orlando, Florida.

    The ISA96.05 subcommittee, Partial Stroke Testing for Valve Actuators, will hold a subcommittee meeting at the SIS-Tech offices in Houston, Texas, on Wednesday, June 26th to coincide with the Valve World Americas Expo and Conference 2013, June 25-26 at the George R. Brown Convention Center. At a recent ISA96.05 meeting, there was discussion of the related International Instrument Users' Association WIB draft guidelines and their relation to the ISA technical report. Input has been gathered from partial stroke testing manufacturers and users, and ISA96.05 is ready to begin work on the revision of ANSI/ISA-TR96.05.01, 
    Partial Stroke Testing of Automated Block Valves. For more information on the ISA96 Valve Actuator Standards Committee, contact Eliana Brazda at ebrazda@isa.org.
