SA-435/SA-435M SPECIFICATION FOR STRAIGHT-BEAM ULTRASONIC
                        EXAMINATION OF STEEL PLATES
1. Scope
1.1 This specification covers the procedure and acceptance standards for straight-beam, pulse-echo, ultrasonic examination of rolled fully killed carbon and alloy steel plates, 1⁄2 in. [12.5 mm] and over in thickness. It was developed to assure delivery of steel plates free of gross internal discontinuities such as pipe, ruptures, or laminations and is to be used whenever the inquiry, contract, order, or specification states that the plates are to be subjected to ultrasonic examination.

SA-578/SA-578M SPECIFICATION FOR STRAIGHT-BEAM ULTRASONIC EXAMINATION
                        OF ROLLED STEEL PLATES FOR SPECIAL APPLICATIONS
1. Scope
1.1 This specification covers the procedure and acceptance standards for straight-beam, pulse-echo, ultrasonic examination of rolled carbon and alloy steel plates, 3⁄8 in. [10 mm] in thickness and over, for special applications. The method will detect internal discontinuities parallel to the rolled surfaces. Three levels of acceptance standards are provided. Supplementary requirements are provided for alternative procedures

学习了！再请教一下，是否可以理解为SA-578 的检测效果比SA-435更好，所以使用在特殊场合呢？

不是了，只是重点不一样，A578主要检测分层特别是用于主要构件如行车梁，压力容器等，

其实标准上就有很明确的应用范围，仔细对一下
