GB/T 4162-2022 (English Version) PDF

Scope: This document specifies the general requirements, instruments and equipment, comparative test blocks, testing procedures, testing procedures, testing result evaluation, quality grade, testing records and testing reports for ultrasonic testing of wrought and rolled steel bars (hereinafter referred to as "steel bars"). This document is applicable to the detection of steel rods with a diameter not less than 6 mm by the ultrasonic pulse-echo method. Forged rods or non-bars of other specifications or materials can be used as a reference. This document does not apply to the detection of austenitic coarse-grained steel rods.
