1 Scope This standard specifies the general requirements, reference samples, testing instruments and equipment, testing conditions and methods, flaw testing and evaluation, quality grading of steel plates and testing report, etc. for ultrasonic testing of thicker steel plates. This standard is applicable to the ultrasonic testing of steel plates (not less than 6mm in thickness) used in pressure-bearing element, bridge, building, shipbuilding, steel structure, pipeline and mould, etc. Austenitic stainless steel plate may also make reference to this standard. 2 Normative References The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. GB/T 8651 Flaw Detection Method by the Ultrasonic Plate Wave for Metal Plates JB/T 10061 Commonly Used Specification for A-mode Ultrasonic Flaw Detector Using Pulse Echo Technique 3 General Requirements 3.1 The surface of the inspected plate shall be leveling, smooth and uniform in thickness, free from any liquid drop, oil stain, corrosion and other dirt. 3.2 The internal structure of the inspected plate shall not generate any interference echo to the inspection when testing. 3.3 The testing site shall sheer off bright light, intense magnetic field, strong vibration, corrosive gas and severe dust, etc. that will influence the stability of the ultrasonic fault detector and the reliable observation of the inspector. 3.4 The personnel engaged in steel plate ultrasonic testing shall be well-trained and obtain the Class I qualification certificate or above in the discipline of ultrasonic testing issued by the certification authority. The flaw detection report issuer shall obtain Class II qualification certificate or above in the discipline of ultrasonic testing issued by certification authority. 3.5 The scanning may be manual or automatic; as for testing method, piezoelectric ultrasonic (contact method and immersion method) and electromagnetic ultrasonic testing may be adopted.
