Foreword
GB/T 27664 "non-destructive testing and performance testing ultrasonic testing equipment" is divided into three parts.
--- Part 1. Apparatus;
--- Part 2. Probes;
--- Part 3. Combined equipment.
This section GB/T 27664 Part 2.
This section drafted in accordance with GB/T 1.1-2009 given rules.
This section uses redrafted law revision adopts the European standard EN12668-2.2001 "NDT ultrasonic testing equipment and performance
Test - Part 2. Probe "(in English), including its No. 1 amendments EN12668-2.2001/Amel.2004.
Text structure and technical content of this section with EN12668-2.2001 agreement.
This portion of EN12668-2.2001 and the difference between the following reasons.
--- Remove the EN foreword, and re-write the foreword;
--- Use the "section" word instead of the "European standard";
--- Deleted Chapter 1 probe testing requirements;
--- Amend the introductory phrase in Chapter 2, "Normative references" in;
International Standard --- Chapter 2 normative references cited in the country has been transformed into a standard, then this part of the direct references thereto

Non-destructive testing - Ultrasonic testing and performance testing equipment
Part 2. Probe
1 Scope
This section GB/T 27664 specifies the following two types of focus or focus ultrasonic probe for detection and non-destructive testing methods.
a) generating transverse or longitudinal wave transducers single or dual transducer contact probes;
b) immersion probe.
Ultrasound and materials related to the value specified in this section is based on longitudinal wave acoustic velocity of (5920 ± 50) m/s and transverse ultrasonic sound
Speed \u200b\u200bof (3255 ± 30) m/s steel.
This part of the cycle test method does not provide for the probe.
This section applies to a center frequency at 0.5MHz ~ 15MHz range focus or focus probe.
