Latest version of the standard

It should be available to check on the website for accessing APIs, right?

It’s more enjoyable when good things are shared among everyone.

API is the abbreviation for the American Petroleum Institute. Founded in 1919, API is the first **-level business association in the United States. An important task of API is to oversee the standardization of equipment used in the oil and gas industry, in order to ensure the safety, reliability, and interchangeability of the equipment employed in this sector. API enjoys a high reputation both within the United States and abroad; the technical standards it establishes for the petrochemical and oil extraction industries are adopted by many companies. It is an oil machinery certification body recognized by the U.S. Department of Commerce and the U.S. Trade Commission. The authentication standards of API enjoy a high reputation internationally as well. Petroleum machinery bearing the API mark is considered not only to be of reliable quality but also to possess advanced technical capabilities. API standards are divided into three main categories: 1. Specifications for the design and manufacture of petroleum equipment ； 2. Recommended practices for the use and maintenance of petroleum equipment ； 3. Recommended practices for drilling and strip mining operations. Under normal circumstances, API standards are reviewed, modified, reconfirmed, or revoked at least once every 5 years. Sometimes the review period can be extended once, but not by more than 2 years. Therefore, except for authorized extensions to the re-publication period, API standards become invalid 5 years after their date of publication. API does not require mandatory laboratory testing for products applying for certification, but it has established 55 detailed specifications for various devices used in the oil and gas exploration and processing industries. For example, the 6D specification covers pipeline valves, including ball valves, gate valves, check valves, etc. These specifications define the minimum requirements that products must meet. Although mandatory testing is not required, API’s observers will review the product plans submitted by manufacturers to ensure that they follow the product planning system during the production process. The latest version of API610 is version 10, in English; a Chinese version is available in China. It is titled \"Centrifugal Pumps for the Oil, Petrochemical, and Natural Gas Industries\", published by the American Petroleum Institute in 2004. This standard sets out the minimum requirements for centrifugal pumps used in the oil, petrochemical, and natural gas industries, providing detailed specifications regarding basic design, accessories, inspections, testing, and other aspects. However, strict adherence to API 610 10TH does not simply mean that the cost of pumps will increase significantly. API674 is the standard for reciprocating piston pumps. API675 is the standard for positive displacement pump – volume-controlled metering pumps. API676 is the standard for positive displacement pump – rotary rotor pumps.
