is the American Petroleum Institute’s technical standard for Pulsation and Vibration Control in positive displacement (PD) machinery systems. Intertek Inform Core Purpose
Dampeners must reduce the dominant pulsation frequency amplitude by at least 80% unless otherwise justified by a risk assessment.
API 688 defines how engineers should approach the "interplay" between acoustic resonances and mechanical natural frequencies. Design Approaches (DA): DA 1: Preliminary sizing based on empirical formulas. DA 2: Pulsation study with a basic mechanical review. api 688 pdf

The American Petroleum Institute (API) published a technical report on Pulsed Eddy Current (PEC) inspection of heat exchanger tubes, which is API 688. This report provides guidelines for the use of PEC technology to inspect heat exchanger tubes in the petroleum, petrochemical, and natural gas industries.
