INSPECTION 检查 三 Inspection Procedures

NOTE: The CMM, ASB, or SB, takes precedence. If no procedure is specified, refer to ASTM E1417 for the fluorescent penetrant procedure to inspect parts or materials. See also AMS 2647.

注：CMM、ASB或SB规范优先适用。若未指定检测程序，则参照ASTM E1417执行荧光渗透检测。另参见AMS 2647。

(1) General

总则

(a) Parts must be cleaned to remove oil, grease dirt, etc. See CLEANING, Chapter 3. However, paint may remain in place.

零件必须清洁以去除油污、油脂、污垢等。参见第3章“清洁”。但涂层可保留。

(c) Liquid penetrant examination of parts or material must be done in accordance with a written procedure as outlined in ASTM E1417 and must be signed and approved by the facility level III certified in the liquid penetrant test method. The procedure must include the specific information concerning the facility equipment, calibration requirements, material, process controls, and parameters to be used or be in conjunction with a technique card that contains this same specific information necessary to inspect that part. All technique cards, if used, must also be signed and approved by the facility level III certified in the liquid penetrant test method.

零件或材料的液体渗透剂检测须遵循ASTM E1417规定的书面程序，并由具备液体渗透剂检测方法三级认证的机构签字批准。该程序须包含关于机构设备、 校准要求、材料、工艺控制及参数等具体信息，或与包含同等必要检测信息的操作技术卡配套使用。所有操作技术卡（如适用）亦须经液体渗透检测方法三级认证人员签字批准。

(d) If parts were previously inspected with non-fluorescent penetrant at an earlier stage, assurance must be made that the non-fluorescent dye has been completely removed before fluorescent penetrant application.

若零件在前期阶段曾使用非荧光渗透剂检测，必须确保在施加荧光渗透剂前已彻底清除非荧光染料。

(e) Etching before penetrant inspection must only be done when specified in the Component Maintenance Manual. Refer to INSPECTION, Chapter 5, Section 2, Task 7 for procedure.

渗透检测前的蚀刻处理仅限于组件维护手册明确规定的情况。具体操作流程参见《检验》章节第5章第2节任务7。

(2) Penetrant Systems, Refer to Table 503

渗透剂系统，参见表503

(a) For all parts and/or materials, except finished machined castings and rotating parts, use Type 1, Level 2. Method B or D. For flight critical parts, add Form D.

除精加工铸件及旋转部件外，所有零件和/或材料均采用I型2级B法或D法。飞行关键部件需追加D表。

(b) For all castings, except rotating castings, use Type I Level 1. Method A, B, or D.

除旋转铸件外，所有铸件均采用I型1级A法、B法或D法。

(c) For all parts identified as high speed rotating parts, use Type 1, Level 3, Method B or D.

所有标识为高速旋转部件的零件，采用1型3级B法或D法。

(d) If so specified in the Component Maintenance Manual, it is permissible to substitute a higher sensitivity level.

若部件维护手册另有规定，可采用更高灵敏度等级。

(e) Penetrant dwell time is 30 minutes minimum.

渗透剂停留时间不少于30分钟。

(f) Non-fluorescent penetrant is only used when specified by the controlling documents.

非荧光渗透剂仅在控制文件指定时使用。

(3) Acceptance Requirements – Refer to CMM or other controlling document.

验收要求 – 参照CMM或其他控制文件。

NOTE: The CMM, ASB, or SB, takes precedence. If no procedure is specified, refer to ASTM E1444/E1444M for the Magnetic Particle procedure to inspect a part. (AMS 2301 and ASTM E1444/E1444M are replaced by ASTM E1444/E1444M)

注：CMM、ASB或SB文件优先适用。若未规定检测程序，则参照ASTM E1444/E1444M执行零件磁粉检测。（AMS 2301和ASTM E1444/E1444M已被ASTM E1444/E1444M取代）

(1) General

总则

(a) Inspection personnel must meet the certification requirements of Military Specification MIL-STD-410. At least one person must be certified to a level III in the magnetic particle test method.

检验人员须满足军用规范MIL-STD-410的认证要求。至少一名人员须持有磁粉检测方法三级认证。

(b) Magnetic particle examination of parts or material must be done in accordance with a written procedure as outlined in ASTM E1444/E1444M and must be signed and approved by the facility level III certified in the magnetic particle test method. When a technique is not given in the CMM, the procedure must include the specific information concerning the facility equipment, materials and process to be used or be in conjunction with a technique card that contains this same specific information necessary to inspect that part. This applies when a technique is not given in the CMM. All technique cards must also be signed and approved by the facility level III certified in the magnetic particle test method.

零件或材料的磁粉检测须遵循ASTM E1444/E1444M规定的书面程序，并须由该设施内持有磁粉检测方法三级认证的人员签字批准. 当CMM未规定具体检测技术时，程序文件须包含所用设备、材料及工艺的具体信息，或与载有相同检测零件必需信息的检测技术卡配套使用。此要求适用于CMM未规定检测技术的情况。所有检测技术卡均须经磁粉检测方法三级认证人员签字批准。
