What is ISO 16811 - Sensitivity and range setting in ultrasonic testing about?

ISO 16811 is an international standard that covers sensitivity and range setting in ultrasonic testing, enabling accuracy and precision in the detection of flaws in industrial applications.

ISO 16811 specifies the general rules for setting the timebase range and sensitivity (i.e. gain adjustment) of a manually operated ultrasonic flaw detector with an A-scan display in order that reproducible measurements may be made of the location and echo height of a reflector.

ISO 16811 is applicable to techniques employing a single contact probe with either a single or twin transducers but excludes the immersion technique and techniques employing more than one probe.

Who is ISO 16811 - Sensitivity and range setting in ultrasonic testing for?

ISO 16811 on sensitivity and range setting in ultrasonic testing applies to:

Manufacturers of ultrasonic testing equipment
Testing houses and labs for ultrasonic equipment
Non-destructive testing agencies
Quality assurance services
Simulation testing services

Why should you use ISO 16811 - Sensitivity and range setting in ultrasonic testing?

Ultrasonic testing (UT) is a non-destructive test method for detecting cracks and defects in components and materials using sound waves. The accurate measurement and evaluation of the product require appropriate sensitivity and range settings, that will vary depending on the products in consideration.

ISO 16811 provides users guidance on the categories of test objects including, plane parallel surfaces, parallel curved surfaces, complex shapes and more, enabling users to conduct ultrasonic testing on different shapes and dimensions.

ISO 16811 provides users guidance on the determination of probe index and beam angle, time base setting, sensitivity setting and echo height evaluation, and more, ensuring precision and accuracy in industrial testing applications.

With obedience and compliance to ISO 16811, users can assess the products for the detection of flaws that ensure product consistency, quality and performance in industrial testing applications.
