标准范围

ISO 12710描述了一套用于测量具有显示屏的超声波检测仪器性能的程序。本国际标准规定了脉冲回波超声无损检测仪器部件性能特性的测量程序，包括带屏幕显示的模拟型和数字型仪器。其目的是建立统一的评估技术，为数据关联和解释在不同实验室和不同时间获得的结果奠定基础。请注意，ISO 12710没有规定验收标准；此类标准应由用户方指定。超声波无损检测仪器的常用部件和性能特征，其中描述了测量这些特征的程序，包括:线路调节；电池放电时间；电池充电时间；脉冲形状；脉冲幅度；脉冲上升时间；脉冲长度；脉冲频谱；垂直线性；频率响应；噪声和灵敏度；数据库控制；水平线性；时钟（脉冲重复率）；延迟和宽度；决议警报级别；获得均匀性；模拟输出；后回音门线性。

ISO 12710 describes a set of procedures for the measurement of any performances in an ultrasonic test instrument that has a display screen.This International Standard establishes the procedures for measuring performance characteristics of components of pulse-echo ultrasonic non-destructive testing instruments including both analog and digital type instruments with screen displays. The aim is to establish uniformity of evaluation techniques, to form a basis for data correlation and for interpretation of results obtained from different laboratories and at different times. Note that ISO 12710 establishes no acceptance criteria; such criteria should be specified by user parties.The usual components of ultrasonic non-destructive testing instruments and the performance characteristics for which procedures for measuring these characteristics are described including:line regulation; battery discharge time; battery charge time; pulse shape; pulse amplitude; pulse rise time; pulse length; pulse frequency spectrum; vertical linearity; frequency response; noise and sensitivity; dB controls; horizontal linearity; clock (pulse repetition rate); delay and width; resolution; alarm level; gain uniformity; analog output; back-echo gate linearity.
