API 688 provides the technical framework to prevent mechanical fatigue and structural damage caused by pressure fluctuations. It is primarily used alongside purchasing specifications like API 618 for reciprocating compressors. Reciprocating Compressors (API 618) Rotary PD Compressors (API 619) Reciprocating PD Pumps (API 674) Controlled Volume PD Pumps (API 675) Rotary PD Pumps (API 676)

The development of API 688 was driven by the need for a standardized approach to industrial process surveillance instruments. In the past, there was a lack of consistency in the design, testing, and documentation of these instruments, which led to variability in performance and reliability. api 688 pdf

API 688 is a standard published by the American Petroleum Institute (API) that provides guidelines for the design, manufacture, testing, and documentation of industrial process surveillance instruments. The standard is titled "Industrial Process Surveillance Instruments" and it covers a wide range of instruments used in process industries, such as petroleum refining, petrochemicals, and chemical processing. API 688 provides the technical framework to prevent

API typically reviews and revises standards every 5 years. The current version was reaffirmed in 2020. Always check the revision date in your API 688 PDF (look for "API Std 688, First Edition, Date..."). In the past, there was a lack of

The standard provides technical requirements and modeling techniques for the following equipment:
