What is BS EN ISO 10216-4:2019?

The BS EN ISO 10216-4:2019 is a standard that relates to non-destructive testing of steel tubes. It provides guidelines for the ultrasonic testing (UT) of seamless and welded steel tubes associated with pressure purposes. This standard is part 4 of the ISO 10216 series, specifically focused on testing methods and acceptance criteria.

Testing Methods

Ultrasonic testing is one of the primary methods used for inspecting steel tubes. It involves sending high-frequency sound waves into the material being tested and analyzing the returned signals. The BS EN ISO 10216-4:2019 outlines detailed procedures for performing UT on both seamless and welded steel tubes.

The standard specifies the equipment requirements, such as the type of transducers to be used, calibration procedures, and frequency ranges suitable for different tube sizes and thicknesses. It also covers the positioning of transducers, scanning patterns, and the interpretation of test results.

Acceptance Criteria

In addition to describing testing methods, the BS EN ISO 10216-4:2019 sets out acceptance criteria for the examined steel tubes. These criteria define the maximum allowable indications, such as discontinuities or other flaws, based on their size, shape, and location.

The standard includes tables and diagrams that provide guidance on determining acceptance limits for various types of defects commonly encountered in steel tubes. By following these criteria, manufacturers can assess the quality of their products and ensure they meet the required standards for effective performance and safety.

Importance and Compliance

BS EN ISO 10216-4:2019 is an essential standard in the steel tube industry. By complying with its testing methods and acceptance criteria, manufacturers can guarantee the quality and reliability of their products. This ensures that steel tubes used in various applications, such as pressure vessels or pipelines, are free from significant defects that could compromise their structural integrity.

Compliance with this standard also allows for consistency in the interpretation of test results across different manufacturers, facilitating fair competition and ensuring end-users receive reliable products that meet industry standards.
