8数据分析凡超过下列8.1或8.2所示限值的反射体,先应确定其超声信号显示是缺陷信号显示还是几何信号显示。若反射体判定为缺陷,应按本文第9节验收评定。8.1波幅法(A扫描)凡信号波幅超过20%DAC基准线、即超过评定线的缺陷,应确定其位置、波幅和长度范围。8.2非波幅法(B扫描、D扫描、S扫描)凡指示长度超过下列限值的缺陷显示图像,应确定其位置和长度范围:
8 Data Analysis Reflectors exceeding the limits shown in 8.1 or 8.2 below should first be determined whether their ultrasonic signal is displayed as a defect or geometric signal. If the reflector is determined to be defective, it shall be accepted and evaluated in accordance with Section 9 of this paper. 8.1 Vibration method (A-scan) Where the signal amplitude exceeds 20% of the DAC reference line, ie the defect over the evaluation line, its position, amplitude and length range shall be determined. 8.2 Non-amplitude method (B-scan, D-scan, S-scan) Where a defect indicates that the length of the display exceeds the following limits, its position and length range should be determined:
