Non-destructive testing - Ultrasonic testing - Transmission technique

ISO 16823:2012 specifies the principles of transmis­sion techniques. Transmission techniques can be used for: a) detection of imperfections; b) determination of attenuation. The general principles required for the use of ultrasonic examina­tion of in­dustrial products are described in ISO 16810. The transmission technique is used for examination of flat pro­ducts, e.g. plates and sheets. Further, it is used for examinations e.g.: 1) where the shape, dimensions or orientation of possible imperfections are unfavourable for direct reflection; 2) in materials with high attenuation; 3) in thin products.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
