ASME PTC 9 (Displacement Compressors, Vacuum Pumps and Blowers) is a historical performance test code that provides uniform rules for conducting and reporting tests on displacement-type machinery. While it was last reaffirmed in 1997, it has largely been superseded in modern industrial practice by ASME PTC 13 and ISO 1217 . Core Features of ASME PTC 9 The code established mandatory procedures for determining machine performance under specific operating conditions: Capacity Assessment : Precise rules to measure capacity relative to speed, inlet pressure, and discharge pressure. Power Consumption : Standardized methods to calculate power use in relation to speed, capacity, and intercooling. Test Reconciliation : Specialized rules for adjusting raw test results to reconcile them with specified or "guaranteed" operating conditions. Measurement Standards : Definitions for required instruments and mandatory computational formulas (Section 5) to ensure results comply with ASME standards. Pulsation Management : Guidelines for testing compressors in environments where gas discharge is uniform and free from the pulsations inherent in displacement machinery. Current Status and Availability Although the code is technically "inactive" or "superseded," it remains relevant for historical reference or legacy equipment testing: Latest Edition : The final version is the 1970 edition, which was reaffirmed in 1997 (PTC 9-1970 R1997). Where to Obtain : Official digital or printed copies are available through the ASME Standards Catalog or authorized distributors like Accuris (formerly IHS Markit) . Transition to PTC 13 : For new installations, particularly "wire-to-air" blower systems, ASME PTC 13 is now the preferred standard as it incorporates modern advancements that PTC 9 did not address.

ASME PTC 9 (Performance Test Code 9) is a historical standard for testing displacement compressors, vacuum pumps, and blowers . While the official 1970 version is technically superseded, it remains a vital reference for engineering professionals evaluating legacy equipment or positive displacement machinery. The American Society of Mechanical Engineers - ASME Overview of ASME PTC 9 The primary goal of the code is to provide uniform rules for determining the performance of positive displacement machines. These machines are characterized by pulsating flow, which makes standard testing methods challenging. Intertek Inform Key Parameters Measured: in relation to speed, inlet pressure, and discharge pressure. Power Consumption relative to speed, capacity, and intercooling. Primary Application: Testing compressor units where gas can be discharged into the atmosphere, pipelines, or receivers maintained free of pulsations. The American Society of Mechanical Engineers - ASME Status and Availability Current Standing: The latest full edition is ASME PTC 9-1970 , which was reaffirmed in 1997. Historical Reference: ASME now classifies this as a historical reference standard rather than an active American National Standard. Supersession: In many modern contexts, it has been superseded by ASME PTC 10 (Performance Test Code on Compressors and Exhausters), though PTC 10 is often more focused on centrifugal and axial compressors. Official PDF: The authorized ASME PTC 9 PDF is available for purchase and download through the official ASME store The American Society of Mechanical Engineers - ASME Best Practices for Performance Testing When applying PTC 9 or similar displacement compressor standards, engineers follow these core guiding principles: Uniform Conditions: Tests must be conducted under conditions that allow for stable, non-pulsating discharge to ensure accurate measurement. Mandatory Procedures: Sections covering instrument specifications, computation formulas, and reporting formats are mandatory for a test to be "in accordance" with the code. Measurement Uncertainty: ASME PTC 19.1 (Test Uncertainty) alongside PTC 9 is recommended to determine the statistical quality of the test results. Alternative Standards: For modern "low-pressure" blowers, the CAGI BL300 code is often used as a simplified "wire-to-air" performance methodology.

ASME PTC 9: Performance Test Code for Reciprocating and Rotary Pumps Introduction The American Society of Mechanical Engineers (ASME) has developed a performance test code for reciprocating and rotary pumps, designated as ASME PTC 9. This code provides guidelines for conducting performance tests on pumps to determine their hydraulic performance, efficiency, and other key parameters. The code is widely used in the industry to ensure that pumps meet their design specifications and to provide a basis for comparing the performance of different pumps. Scope ASME PTC 9 applies to reciprocating and rotary pumps, including positive displacement pumps, such as piston pumps, plunger pumps, and rotary pumps, such as gear pumps, vane pumps, and screw pumps. The code covers pumps used in various industries, including petroleum, chemical, power generation, and water supply. Objectives The primary objectives of ASME PTC 9 are:

To provide a standardized method for conducting performance tests on reciprocating and rotary pumps. To ensure that pump performance data are accurate, reliable, and comparable. To provide a basis for evaluating pump performance against design specifications and industry standards. asme ptc 9 pdf best
