Introduction

GB/T 27664.3 "Performance and Inspection of Ultrasonic Testing Equipment for Nondestructive Testing - Part 3: Combined Equipment" specifies the use of appropriate...

The measurement methods and acceptance criteria for determining the working characteristics of an ultrasonic testing instrument and ultrasonic probe combination using standard test blocks are described. This applies to production or application environments.

This is applicable to all users and its purpose is to inspect whether the combined equipment is working properly and whether its performance meets the requirements after production or before use.

GB/T 27664 "Performance and Inspection of Ultrasonic Testing Equipment for Nondestructive Testing" is divided into the following three parts.

---Part 1: Instrumentation. The purpose is to clarify the performance characteristics of the A-type pulse ultrasonic testing instrument, its measurement methods, and acceptance procedures.

standard.

---Part 2: Probes. The purpose is to clarify the performance testing of ultrasonic probes after fabrication, including measurement methods and acceptance procedures.

standard.

---Part 3: Combined Systems. The purpose is to illustrate the determination of the combination of an ultrasonic testing instrument and an ultrasonic probe using appropriate standard calibration blocks.

Measurement methods and acceptance criteria for working characteristics.

GB/T 27664, "Performance and Inspection of Ultrasonic Testing Equipment for Nondestructive Testing," consists of three independent parts that also complement each other, forming a comprehensive standard.

A complete standard system describes the measurement and verification methods for the performance of A-pulse ultrasonic testing instruments, probes, and combined systems.

1 Scope

This document specifies the use of ultrasonic testing equipment (including instruments, probes, and connectors) with calibration blocks appropriate for the testing purpose to verify the assembly.

Methods and acceptance criteria for cable performance.

The methods specified in this document are primarily applicable to manual single-channel ultrasonic testing instruments conforming to ISO 22232-1 and those conforming to ISO 22232-2.

This document describes manual ultrasonic nondestructive testing using single-crystal or dual-crystal probes. It also applies to multi-channel instruments. For automated testing equipment, [further details are needed].

Additional testing may be required to ensure satisfactory performance.

The methods specified in this document are applicable to operations performed by personnel under on-site or workshop conditions.

The methods specified in this document are not applicable to proving that the equipment is suitable for a specific application.

This document does not apply to ultrasonic instruments that use continuous waves.

This document also does not apply to phased array ultrasonic systems (see ISO 18563-3). When phased array instruments are combined with single-crystal or dual-crystal probes...

This document applies to this combination.
