API History
1919: API founded as non-profit national trade
association, New York City
1980s: API relocates to Washington, DC
1995: API Dallas Standards Office relocates to
Washington, DC

Background on API Standards
Program
The API Standardization Department was formed
in 1923, with the first API standard published the
following year on drilling threads.
All industry segments now active in
standardization:
• Exploration and Production
• Pipeline Transportation
• Refining
• Marketing
5
API Standards
• API now publishes more than 600
technical standards covering all aspects
of the oil and natural gas industry
• Foundation of Self Supporting Programs
• Basis for Worldwide Operations
• Core of Institute’s Technical Authority
6
Standards Development Process
• The API Standards program is accredited by
the American National Standards Institute
(ANSI) – the program was reaccredited by
ANSI in Oct. 2011 following a 2010 audit.
- Openness, Balance, Consensus, Due Process
- Regular program audits (conducted by ANSI)
• Transparent process (anyone can comment on
any document in process)
- All comments must be considered
7
Standards Development Process
• Developed by consensus (does not mean unanimity)
• Committee balance between users/owner operators,
manufacturers and contractors/consultants
• Standards developed using ANSI approved API
Standards Development Procedures (available on-line
at www.api.org)
• API corporate membership is not a requirement for
participation on API standardization committees.
• Support from your management to participate is.
8
Use of API Standards
• “De facto” international standards
• Adoption by reference common by State and
Federal agencies – BSEE, USCG, DOT, OSHA
and EPA
• API does not promote adoption - prefer voluntary use
• Written for flexibility as performance based
documents
9
API Standards Committee Structure
Committee on
Standardization of
Oilfield Equipment
& Materials
Committee on
Petroleum
Measurement
Committee on
Refinery
Equipment
• Marketing/Aviation
• Pipeline Transportation
• Safety & Fire Protection
To support the Standards there are Certification programs:
API Monogram Program, Individual Certification Programs
and others,
www.api.org
- Certification Programs
10
AST Standards
API publishes over 70 standards, recommended practices, and bulletins
covering various aspects of tank operations
– Design & Construction
– Inspection
– Measurement and emissions
– Safety & Fire Protection - Safe Entry, Overfill Protection
– Environmental - Leak detection, Release Prevention, Emissions

AST Standards - History
[From 653 - Annex A: Background on Past Editions of
API Welded Storage Tank Standards]
• API published a specification for welded steel storage
tanks in July 1936 entitled API Standard 12C, All-Welded
Oil Storage Tanks. Fifteen editions and seven
supplements to API 12C were published between 1936
and 1958.
• API 12C was replaced by API Standard 650, Welded
Tanks for Oil Storage in December 1961; 11 editions and
22 supplements, revisions or addenda to API 650 have
been issued since.
12
Design & Construction
API 620, Design and Construction of Large, Welded,
Low-Pressure Storage Tanks
• Designed for metal temperatures not greater than
250°F and with pressures in their gas or vapor
spaces not more than 15 lbf/in. sq. gauge
• Appendix Q covers liquefied gases at temperatures
not lower than –325°F
• Appendix R covers refrigerated products at
temperatures from +40°F to –60°F
13
Current Edition of API 620
• Addendum 3 to the 11th Edition was
published March 2012
• The 12th Edition is currently being worked
