5 General
The purpose of this document is to describe general methods of ultrasonic examination for the most
commonly used welded joints in thermoplastics. The specific requirements specified by this document cover
the equipment, preparation, performance of the examination and reporting. Methods to be used for ultrasonic
assessment of indications and acceptance criteria shall be specified.
6 Information required prior to examination
6.1 Examination procedure
The following items shall be specified:
 method for setting the reference level;
 method to be used for evaluation of indications;
 acceptance levels;
 examination level;
 manufacturing and operation stage(s) at which the examination is to be carried out;
 qualification of personnel;
 whether or not a written examination procedure is required;
 requirements for written examination procedures.
6.2 Information required by the operator
Before any examination of a welded joint can begin, the operator shall have access to the following
information:
 written examination procedure, if required (see 6.3);
 type(s) of parent material;
 joint preparation and dimensions;
 welding procedure or relevant information on the welding process;
 reporting requirements.
6.3 Written examination procedure
The definitions and requirements in this document will normally satisfy the need for a written examination
procedure. When this is not the case, or when the techniques described in this document are not applicable to
the welded joint to be examined, additional written examination procedures shall be used.
7 Requirements for personnel and equipment
7.1 Personnel qualifications
Personnel performing examinations in accordance with this document shall be qualified to an appropriate level
in accordance with the relevant document, e.g. EN 473.
In addition to a general knowledge of ultrasonic weld inspection, the personnel shall be aware of testing
problems specifically associated with the thermoplastic material and type of welded joints to be examined.
7.2 Equipment
Any equipment used in conjunction with this document shall comply with the requirements of EN 12668-1 to
EN 12668-3. Prior to the publication of a document related to the subject, the corresponding national
documents may be used.
7.3 Probe parameters
7.3.1 Frequency
Only longitudinal (compression) wave transducers shall be used for the inspection of thermoplastics. The
frequency of the transducers shall be in the range 1 MHz to 5 MHz and shall be chosen such that flaw
sensitivity is maximised without compromising signal-to-noise performance.
To improve signal-to-noise performance piezo-composite transducers may be used.
7.3.2 Angles of incidence
The probe angle(s) used shall ensure that the weld fusion face(s) are examined at, or as near as possible to,
normal incidence. This means that for electrofusion joints, for example, a 0° probe angle shall be used.
7.3.3 Focusing
For the examination of electrofusion joints focusing probes should be used. These probes shall be focused to
the depth of the welded interfaces, i.e. their focal distance shall be equal to the wall thickness of the socket.
Focused probes should not be used for the examination of heated tool, extrusion or hot gas welded joints
unless otherwise specified.
7.3.4 Wedge material
Wedges should be made of PTFE.
7.3.5 Adoption of probes to curved scannin
