Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces GB/T 11259-2008 "NDT ultrasonic testing of steel production parameters and test methods test block."
This standard 11259-2008 major changes compared to GB/T as follows.
--- Modify the standard name;
--- Modify the scope (see Chapter 1; Chapter 1 of the 2008 edition);
--- Modify the production process (see Chapter 6; Chapter 6 of the 2008 edition);
--- Modify the physical characteristics of the test (see Chapter 7; Chapter 7 of the 2008 edition);
--- Identify and modify the test piece surface condition (see Chapter 9; Chapter 9 of the 2008 edition);
--- Increased normative appendix "artificial defect cover-die production process" (see Appendix A).

NDT Ultrasonic testing of steel reference blocks
Production and control methods
1 Scope
This standard specifies the reference ultrasonic testing of steel production and control procedures for the examination block, a flat-screen sound wave test block, a cylinder shape,
Contained within the flat bottom hole (FBH), ultrasound can be used for performance testing instruments and probes, as well as calibration and control alloy products ultrasonic testing. The
Said reference blocks both for direct contact method is also applicable to the liquid immersion pulse-echo method.
Although this standard is basically discusses the production and testing of carbon steel and alloy steel test block, and the detection of these materials, but its production and inspection
Test specimen preparation method is also applicable to other materials, such as nickel-based alloys, such as aluminum in some. When produced in addition to carbon and alloy material
The reference test block, may need some additional procedures and tests. In certain applications, this standard does not necessarily rule out some normative and think
To some additional additional requirements.
Other shapes steel production parameters and test control block, may refer to this standard use.

3 Terms and Definitions
Terms and definitions GB/T 12604.1 and GB/T 20737 apply to this document defined.
4 Overview
This standard is described in detail with the subject material commensurate carbon and alloy steel reference blocks of basic production and control procedures, and clearly should meet
Minimum requirements. When making use of the standard reference test block other types of materials or larger diameter, you may need to add additional requirements.
Physical properties of the hole can be confirmed by evaluating the plastic replicas. It should be appreciated that the use of replicas to evaluate pore size limitations.
5 Material Selection
5.1 is used as reference block material should be seized materials have similar acoustic attenuation properties. Match acoustic response should consider the following variables. Crystal
Size, heat treatment, physical and chemical composition, surface roughness and manufacturing processes (rolling, forging, etc.).
5.2 Overall assessment procedure that should be introduced into the longitudinal beam pulse echo test block on either side of the beam axis is determined using a metallic sound away.
Use clean water as a coupling agent in the liquid immersion method or by using a suitable coupling agent (oil, glycerine, etc.) are available for direct contact. Making reference blocks
Evaluation of the raw materials testing equipment, frequency and the probe should be used for detection of the product material fairly.
