About The Committee:
The Gas Piping Technology Committee is an ANSI Accredited Standards Committee (ASC) designated as GPTC/Z380 which maintains and develops ANSI Z380.1, Guide for Gas Transmission, Distribution, and Gathering Piping Systems (Guide). Committee members include persons with expertise from the natural gas transmission, distribution and manufacturing fields as well as from federal and state regulatory agencies. The Committee has approximately 100 members, 40 of which have voting rights and are known as the Main Body. The Main Body is balanced in accordance with ANSI requirements under the following categories: gas transmission, gas distribution, manufacturing, regulatory and the general interest. The Committee is structured into three Divisions and has a number of standing Task Groups and Sections that develop and approve Guide Material.
A history of the GPTC is available HERE.
As an accredited ANSI standards committee, our operating procedure is subject to ANSI review and approval. Our current approved procedure is available to review HERE.
The Gas Piping Technology Committee follows the American Gas Association Anti-Trust Guidelines which are available HERE.
The committee meets three times each year in March, July and November. Meeting locations are rotated around the continental U.S. and typically run for 2 days. Members are required to attend all meetings. If you can not attend a meeting then notification must be provided in advance. Failure to routinely attend meetings is a reason for membership termination. Therefore, members must commit themselves to travel expenses for three meetings per year. Meeting attendees are also required to pay a meeting registration fee to cover committee expenses.
How To Join:
The Committee welcomes new members who start their committee participation as non-voting members. Regardless of voting status, all members are expected to fully participate in developing guide material and attend meetings. To become a new member, complete the application form and return it along with a resume to the ASC Z380 Secretary (address is on the form). A membership term is for 3-years and can be renewed. All memberships are subject to Main Body ballot.
Please submit your application or questions to Luis Escobar, Secretary, ASC Z380, at firstname.lastname@example.org and copy GPTC@aga.org.
ANSI B109 Family of Standards
For Gas Displacement Meters and Service Regulators
The B109 Committee oversees the development and maintenance of consensus standards related to gas meters and service regulators. View the latest B109 Committee Roster and the current B109 Committee Procedures.
Currently, there are four B109 standards that have achieved recognition by the American National Standards Institute (ANSI):
- B109.1 Diaphragm-Type Gas Displacement Meters (Under 500 Cubic Feet Per Hour Capacity) – 2019 Edition
- B109.2 Diaphragm-Type Gas Displacement Meters (500 Cubic Feet Per Hour Capacity and Over) – 2020 Edition
- B109.3 Rotary-Type Gas Displacement Meters – 2019 Edition
- B109.4 Self-Operated Diaphragm-Type Natural Gas Service Regulators for Nominal Pipe Size 1-1/4 Inches (32 mm) and Smaller with Outlet Pressures of 2 psi (13.8 kPa) and Less – 2021 Edition
Purchase a copy of each standard in the AGA Publication Store.
Please contact Luis Escobar at email@example.com if you are interested in becoming a member or observer of ANSI B109, or if you would like to be part of the review process for any of the standards above.
Submitting Proposed Changes:
The ANSI B109 Standards are under continuous maintenance therefore anyone may propose changes to the standards at any time. Each change will be considered by the B109 Committee at their next meeting, and may be referred to a standard-specific task group for their review and recommendation before the next B109 Committee meeting.
If you have a proposed change to any of the standards above, please fill out this form and submit to the B109 Committee Secretary, Luis Escobar at firstname.lastname@example.org.
ANSI Public Review: B109.6 Standard
The Draft of the new proposed B109.6 Standard (Single Path Ultrasonic Gas Meter under 1400 cubic feet per hour capacity) is available for review and comment. Public comments are due to email@example.com by July 3, 2023 and must be submitted on this Public Comment Form.
2022 Fall Committee Meeting
The B109 Committee met on Wednesday, September 14, 2022 at the Disneyland Hotel in Anaheim CA in conjunction with the 2022 AGA Operations Section Fall Committee Meetings. Meeting agenda posted in August 2022.
[CLOSED] Comment Period: Scope Revision
AGA has submitted revisions to the scope of the accreditiation on file with ANSI for the B109 committee. The revised scope is as follows: “Accredited Standards Committee B109 is responsible for the development and maintenance of standards for gas meters, gas service regulators and related devices that are used in the revenue measurement of fuel gas. For both new types and newly constructed meters and service regulators, these standards include: definitions, construction criteria, performance criteria, test methods, in-service performance criteria, installation requirements/practices, and equipment.” Please submit any comments or questions by July 11, 2022 to Luis Escobar, firstname.lastname@example.org.
ANSI approved the revised B109.4 Standard on October 22, 2021 (announcement on page 28 of the October 19th ANSI Standards Action newsletter). The standard now addresses regulator slam-shuts, including slam-shut test procedures and marking requirements. ANSI B109.4-2021 was added to the AGA publication store on November 24, 2021 and is now available for purchase.
