Foreword

This standard is modified using ASTME114-95 (2001) "Contact ultrasonic pulse echo direct detection method" (English version). This standard is redrafted according to ASTME114-95. Taking into account our national conditions, in the use of ASTME114-95, the standard made some changes. The technical differences are as follows. --- the normative reference document ASTME543 to our standard GB/T 5616; --- Standardized reference documents SNT-TC-1A, ANSI/ASNTCP-189, NAS-410 to China's standard GB/T 9445; --- the normative reference document ASTME1316 to our standard GB/T 12604.1 and GB/T 20737; --- the normative reference document ASTME317 to our standard JB/T 9214; --- Remove ASTME114-95 of 1.3, 1.4, Table 1 and Chapter 12. For ease of use, this standard has also made the following editorial changes. The word "this method" is changed to "this standard"; --- replace the value of the imperial unit with the value of the international unit system; - insert the lead in GB/T 1.1-2000 in Chapter 2; --- According to the format requirements specified in GB/T 1.1-2000, refer to Chapter 1, Chapter 2, Chapter 4, Chapter 6, Chapter 9, Chapter 10 and Some of the bars in Chapter 11 are modified. This standard is proposed by the National Committee for the Standardization of Non-destructive Testing (SAC/TC56). The drafting of this standard.
