Using ASME Performance Test Codes in the Undergraduate Mechanical Engineering Curriculum
The American Society of Mechanical Engineers Performance Test Codes (ASME-PTCs) are documents promulgated to standardize the testing of mechanical equipment. The primary emphasis of the PTCs is equipment used in power generation, however, PTCs are also available to guide testing of more widely used equipment. The Codes are written so that they can be incorporated into an equipment purchase contract for use in conducting an acceptance test, and they are meant to be applied to a field test as opposed to a laboratory or shop test. There are about 40 “equipment codes” and about 15 “supplements” covering fundamental measurement techniques and test (measurement) uncertainty.
The PTCs can provide a useful bridge between college courses in the energy stem and instrumentation/measurement and the “real world”. Also, the introduction to the ASME Codes and Standards activity and the part that individual engineers play in developing voluntary standards is obvious link to the topics of professional ethics and volunteerism.
There are several ways that the PTCs might be used in undergraduate instruction:
• They might serve as textbooks or reference materials for lecture or laboratory courses • Students may be asked to conduct a PTC-like test on a piece of equipment • A PTC or a portion of it may be assigned for reading, after which students give written or oral reports. • PTCs may serve as reference material in student (experiment) design courses.
This paper reports on experiences using the Performance Test Codes at three different universities and in three different ways. At a small liberal arts-based university students taking an elective course in turbomachinery were required to design and conduct a PTC-quality test on a pump, using the appropriate PTC as a guide. At a medium-sized technical university, students read and reported on PTCs as part of a senior thermal science laboratory course. At a large research university PTCs were used as reference material in a laboratory capstone design course. In addition to instructor’s experiences, assessment data from student surveys are presented.
1. Introduction to Performance Test Codes
A. What Are Performance Test Codes The American Society of Mechanical Engineers (ASME) Performance Test Codes (PTCs) provide uniform rules and procedures for planning, preparation, and execution of performance tests and for reporting the results 1,2. A performance test is an engineering evaluation, based on measurements and calculations, whose results indicate how well the functions of equipment are accomplished. PTCs began as “Power Test Codes” decades ago, so their main emphasis is on power plants and the equipment therein. The first engineering standard of any type issued by ASME was a “PTC”: Rules for Conducting Boiler Tests, published in 1884. Today, there are about 40 PTCs covering specific equipment, entire systems,
