To remain current, standards documents are subject toperiodic review, and at the end of this cycle, standards are either reaffirmed,revised, or withdrawn. As such, many prominent standards see new editions everyfew years, with the revised version superseding the previous one. If you look throughoutthis blog, you will read hundreds of updates regarding the changes made duringstandard revisions.
However, sometimes people need other editions. Whether due to a need to comply with previous editions, the intention of comparing past and current editions of the same standard, or just a desire to have an outdated standard, there is a sizeable demand for historical standards.
For example, the current edition of ANSI/ASHRAE/IES 90.1 was released in 2022. This document provides minimum energy-efficient requirements for the design, construction, operation, and maintenance of buildings and sites and their utilization of on-site renewable energy resources. This American National Standard is one of the two baseline energy conservation codes adopted by regulatory authorities throughout the nation.
Since nearly all states have adopted ANSI/ASHRAE/IES 90.1, with many of them still following its past editions, there is a clear need for professionals to acquire not only the most recent edition of the standard, but also its predecessors.
If you have any questions regarding historical standards or are searching for a specific document, please feel free to reach out to ANSI customer service by emailing in...@ansi.org, calling 212-642-4980, or live chat with a customer service representative 8:30AM-6PM EST Monday-Friday.
This standard, as well as ANSI Z1.2 and ANSI Z1.3, was revised in 1996 by ANSI/ASQC B1-B3-1996: Guide For Quality Control Charts Control Chart Method Of Analyzing Data Control Chart Method Fo Controlling Quality During Production. If you need to find or learn more about the 1952 edition, you might want to reach out for the developer of this standard, ASQ: -service/contact-asq/index.html

The American Gas Association serves as the secretariat to the ANSI Accredited Standards Committee (ASC) Z223 on National Fuel Gas Code. The ASC Z223 develops and publishes ANSI Z223.1, National Fuel Gas Code, which is jointly developed with the National Fire Protection Association (NFPA) 54 Committee and is consequently also known as NFPA 54. View the Z223 Committee Interest Category Balance and Z223 Committee Procedures.
The American Gas Association serves as the secretariat to the Accredited Standards Committee (ASC) Z380, Gas Piping Technology Committee. The GPTC develops and publishes ANSI Z380.1, Guide for Gas Transmission, Distribution and Gathering Piping Systems.
ANSI Z380.1-2018 is maintained under continuous maintenance and a new edition shall be published or the existing edition shall be reaffirmed a minimum of every five (5) years. An addendum shall be published as frequently as necessary between editions. Revisions resulting from public proposals shall be published in an addendum or in the new edition whichever is published first. If no changes are made within four (4) years of the ANSI approval date, ASC Z380 shall apply for reaffirmation of the standard. If you would like to make a proposal to revise ANSI Z380.1-2018, please use the proposal form below
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.
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.
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.
