ISO 17577:2006规定了一种通过反射法对无涂层扁钢产品内部不连续性进行自动和/或手动超声波检测的方法。适用于标称厚度为6 mm至200 mm的非合金或合金扁钢产品。然而,本标准可适用于奥氏体和奥氏体-铁素体钢,前提是噪声信号的振幅与回声检测阈值的振幅之间的差异足以满足固定极限。除非另有约定,对于焊接钢管用扁钢产品的试验,ISO 12094适用。
ISO 17577:2006 specifies a method for the automated and/or manual ultrasonic testing of uncoated steel flat products for internal discontinuities by the reflection method. It is applicable to non-alloyed or alloyed steel flat products, in a nominal thickness range of 6 mm to 200 mm. However, this standard may be applied to austenitic and austenitic-ferritic steels, provided that the difference between the amplitude of the noise signal and that of the echo detection threshold is sufficient for the limit fixed. Unless otherwise agreed, for testing of steel flat products for welded steel tubes, ISO 12094 applies.
