BS EN 16729-1:2016

What is BS EN 16729-1 - Requirements for ultrasonic inspection and evaluation principles about?

BS EN 16729-1 specifies the requirements for testing principles and systems in order to produce comparable results with regard to location, type, and size of discontinuities in rails.

Note1: BS EN 16729-1 is not aiming to give any guidelines for managing the result of ultrasonic rail testing.

Note2: BS EN 16729-1 applies to testing of rails installed in track for detecting internal discontinuities.

Note3: BS EN 16729-1 applies to testing equipment fitted to dedicated test vehicles or manually propelled devices. BS EN 16729-1 does not define the requirements for vehicle acceptance.

Note4: BS EN 16729-1 applies only to rail profiles meeting the requirements of EN 13674‑1.

BS EN 16729-1 on requirements for ultrasonic inspection and evaluation principles is useful for:

• Railway infrastructure regulatory bodies
• Railway engineer
• Operators
• Designers
• Mechanical engineer

Why should you use BS EN 16729-1 - Requirements for ultrasonic inspection and evaluation principles?

BS EN 16729-1 specifies requirements for ultrasonic inspection and evaluation principles uses high-frequency sound energy to conduct examinations and make measurements. BS EN 16729-1 used for flaw detection/evaluation, dimensional measurements, material characterization, and more.

Some of the advantages of BS EN 16729-1 in ultrasonic inspection that are often cited include:

• It is sensitive to both surface and subsurface discontinuities
• The depth of penetration for flaw detection or measurement is superior to other NDT methods
• Only single-sided access is needed when the pulse-echo technique is used
• It is highly accurate in determining reflector position and estimating size and shape
• Minimal part preparation is required
• Electronic equipment provides instantaneous results
• Detailed images can be produced with automated systems
• It has other uses, such as thickness measurement, in addition to flaw detection
