ASME Performance Test Codes:AWide Rangeof Applications

For over 100 years, ASME has been providing industry with acomprehensive collection of the best technical documents to conducttests of power plant equipment and systems. ASME now offers 48Performance Test Codes (PTCs), covering four main categories ofequipment and systems – Power Production, Combustion and HeatTransfer, Fluid Handling, and Emissions. There are also “general”documents that cover Analytical Techniques, Measurement of ProcessParameters and Associated Phenomena and Guiding Information.

ASME PTCs: Ensuring Accuracy, Precision, and Reliabililty.Instilling Confidence.

Performance test codes provide a “level playing field” for bothmanufacturers and users of the equipment or systems. Both parties tothe test can reference the particular test code, confident with the knowl-edge that it represents the highest level of accuracy based on currentengineering knowledge, taking into account test costs and the value ofinformation obtained from testing. Precision and reliability of testresults must also underlie all considerations in the development of anASME PTC, consistent with economic considerations as judged appro-priate by each technical committee under the jurisdiction of the ASMEBoard on Standardization and Testing.

Industry Speaks About ASME Performance Test Codes

“PTC 4, on Fired Steam Generators, is the ultimate comprehensivedocument for defining, calculating and testing for the efficiency of FiredSteam Generators by the Energy Balance Method as well as othersignificant performance parameters. A major feature of the Code is thatit includes the methodology for correcting test conditions toguarantee/reference conditions based upon actual unit performance. TheCode is written in a tutorial manner which enhances use as aninstructive medium as well as providing the methodology for developinga computer code by the user. The Code includes the methodologyfor determining the uncertainty of both the test and corrected results.”

Thomas C. HeilRetiredBabcock & Wilcox

“PTC 6, on Steam Turbines, is the international standard for steamturbine acceptance testing. It was created and recently revised by a con-sensus group of vendors, owners, and users. It provides astandard, consistent, method for determining existing, retrofitted andnew steam turbine performance within the minimum practicaluncertainty. It covers large fossil and nuclear fueled utility grade steamturbine/generators.”

W. Cary CampbellPrincipal EngineerSouthern Company Services

“PTC 4.4, on Heat Recovery Steam Generators, provides a detailedrigorous calculation approach for testing of HRSG’s. The test approachinvolves the determination of the gas turbine exhaust flow by twodifferent means and combining the result. This would apply to multi-pressure HRSG’s including units with auxiliary duct burners.It includes guidance on instrumentation including measuringtemperature of a large exhaust flow stream a method for determining theHRSG test uncertainty.”

Joseph E. SchroederVice President EngineeringNooter Eriksen

“PTC 11, on Fans, provides a reliable method for true testing of fans inthe as-installed condition – without any questionable adjustmentsto performance.”

Philip M. Gerhart, PhDDeanCollege of Engineering & Computer SciencesUniversity of Evansville

“PTC 19.1, Test Uncertainty, provides guidelines to determine thequality of test data, objectively. These methods meet nationaland international standards for objective data quality assessment:measurement uncertainty.”

ASME Codes and Standards – An Overview

ASME: “Setting the Standard” for 125Years

ASME helped pioneer the development of modern industrial codes,beginning with its first published standard in 1884 on pressure-testing for boilers. It seeks to balance interests among its 4,000technical experts drawn from industry, government and academia,while achieving consensus in the finished output. The processremains open and transparent throughout, yielding codes that with-stand scrutiny across markets and jurisdictions.

These development efforts are rigorous and up-to-date, and reflectbest practices of industry. Hence, they have earned the confidenceof regulators around the world and the principles of ASME’sstandards development process are consistent with those of theWorld Trade Organization TBTAgreement. ASME’s more than 500codes are now adopted into law, all or in part, within more than 100nations. These codes and standards are invaluable resources forindustry and governments that help to establish safety and productivityenhancements in areas ranging from operation and maintenance of nuclearpower plants to design of fasteners and plumbing fittings.

About ASME

Founded in 1880 as the American Society of Mechanical Engineers, ASMEis a not-for-profit professional organization promoting the art, science andpractice of mechanical and multidisciplinary engineering and alliedsciences. With a membership of more than 127,000 mechanical engineersand allied professionals from around the world, ASME develops codes andstandards that enhance public safety, and provides lifelong learning andtechnical exchange opportunities to benefit the global engineering andtechnology community.

Over 100Years of ASME PTCs: Ensuring State-of-the-Art Qualityfor State-of-the-Art Technology

In 1884, the ASME published “Rules for Conducting Boiler Tests.”On April 13, 1909, the Power Test Committee was chartered by the Councilof ASME to “revise the present testing codes of the Society relating toboilers, pumping engines, locomotives, steam engines, internal combustionengines …etc.” In 1915, the “Rules for Conducting Performance Test ofPower Plant Apparatus” was published. Over the years numerous test codesand supplements have been published. Some have been revised and otherswithdrawn as new technological advances have necessitated the issuance ofstate-of-the-art test codes. Today, some three dozen test codes are availablefor testing power plant equipment, such as fired steam generators, steamturbines and gas turbines as well as testing fuel cells and combined cyclegasification plants. It is Society policy to review each standard every fiveyears to determine whether a revision is necessary.

ASME Performance Test Codes (PTCs) provide uniform rules andprocedures for the planning, preparation, execution, and reporting ofperformance test results. They provide protocols for establishing testingparameters and methods of measurement. They provide mathematicalexamples on computing the test results and statistical methods to determinethe quality of the tests by calculating the test uncertainty.

Participating on ASME Codes and Standards Committees

ASME PTC Committee Membership

ASME PTCs are developed in committee settings to ensure balanced participation and openaccess to public interest groups. The ASME PTC Standard Committee and supporting technical sub-committees consist of experts from various stakeholder groups, who provide their time and resourceson a voluntary basis. The success of ASME PTCs is based on technical and operational experiencefrom stakeholders drawn from a broad range of industries. The volunteer members who participateon the ASME PTC technical committees play a vital role in ensuring that the published PTCs will beuseful to and used by the wide range of industry users – manufacturers of the equipment or systems,user or owner operators, consultants, testing agencies, governmental agencies and academia.

There are no fees or geographical restrictions associated with membership on the ASME com-mittees or subcommittees. ASME membership is not required. Applicants for committee member-ship are selected based primarily on technical expertise. ASME uses an Internet-based voting andtracking system that allows committee members and other interested parties to participate inongoing business from anywhere in the world. The committee meets at least three times each year todiscuss changing industry needs and best operational practices.

The Standards Development Process

In developing ASME PTCs and other codes and standards, ASME employs a consensus-basedprocess that considers the input of all relevant stakeholders. Due process for all input regardingASME PTCs is assured and monitored. The development process is open to public review at appro-priate stages, and the actions of the committee are documented and completely transparent. TheAmerican National Standards Institute (ANSI) has accredited the Society’s process for the develop-ment of ASME PTCs and other standards. The principles of ASME’s standards development processare consistent with those of the World Trade Organization’s Technical Barriers to Trade Agreement.
