6.1 总则

阀调节器组件应接受与 API 598 相符的验收试验。

在制造、加工、装配、测试和运输期间，所有设备应服从购买者或其提名代表的验收。验收包括设备验证、体积、文档检查和运输准备检查。

 销售者应给出测试进度表前最少15 个工作日的预先通知。所有相关认证文档应在测试前最少48小时发送给购买者提名的代表。测试仅当文档完备且已为购买者或其提名代表获得的情况下才能进行。没有购买者或其提名代表的书面认可，不应进行任何测试。

 购买者保留在制造过程中任何方面的见证权力。
 销售者应早于制造起始向购买者提供一份验收和测试进程 (ITP) 以备购买者检查和认可。ITP 最少应包括：

 i) 制造工序，包括验收。
 ii) 提议的设备实查。
 iii) 提议的 ABV 功能测试。
 iv) 提议的文档检查。
所有阀将进行低氯检验水的水测试。完整的调节器阀组合在销售者前提下应服从功能 FAT。本测试应仅作为阀适合运输的验收而非订单不合格验收。销售者应提供所有人力和所有其他服务促使 FAT 得以执行。

所有阀应接受目视检查以验证购买要求中所有需要的工艺质量和总体一致性。所有相关文档和认证应可做完整性检查。

销售者应至少在测试日程表前 1 个月给购买者提交提议的测试进程以征得认可。

如果制造商建议在运送前阀与调节器共同在工厂进行测试并且能够保证阀在交付后的完备功能，则无需在马来西亚重新测试。但是，如果阀配调节器的测试在制造商的工厂或厂房以外进行，则必须在马来西亚本地进行测试。

6.2 泄漏测试

6.2.1 总则

装配前应进行累加器和10% 调节器的泄漏率测试以证明后备密封安排有效。

如果与最大泄漏率的一致性明显出于后备密封的设计原理，购买者可以放弃这些测试。

6.2.2                 调节器泄漏率测试

对于具有副金属密封圈的调节器，泄漏率应在装配前移除主密封圈下建立。对于不同于副密封圈的，制造商应提出模拟主密封圈故障下的测试安排的建议。
6.1 General

The valve actuator assembly shall be subjected to inspection and testing in accordance to API 598.

All equipment shall be subject to inspection by BUYER, or nominated representative, during the course of manufacture, fabrication, assembly, testing and shipment.  Inspection shall include verification of the equipment, dimensions, examination of the documentation and checking the preparation for shipment.

 SELLER shall give a minimum of fifteen (15) working days prior notice regarding testing schedules. All relevant certified documentation shall be sent to  BUYER's nominated representative at least 48 hours prior to the test.  The test will be witnessed only if the documentation is complete and acceptable to BUYER, or its nominated representative. No testing shall commence without written approval of BUYER, or BUYER's nominated representative.

 BUYER reserves the right to witness any aspects of the manufacturing process.
 SELLER shall submit an Inspection and Testing Procedure (ITP) for review and approval by BUYER prior to the start of manufacture.  The ITP shall as a minimum cover:

 i) Manufacturing sequence, including inspection.
 ii) Proposed physical inspection of equipment.
 iii) Proposed functional test of ABV.
 iv) Proposed check of documentation.
All valves are to be hydro tested with test water of low chloride content. The complete actuator valve assemblies shall be subjected to functional FAT at the SELLER premises. This test shall be considered only as an acceptance that the valves are fit to be shipped and not as an unqualified acceptance of the order. SELLER shall provide all personnel and all other services to enable the FAT to be carried out.

All valves shall be subjected to a visual check to verify quality of workmanship and general conformance with all requirements of the purchase requisition. All associated documentation and certification shall be reviewed for completeness.

SELLER shall submit his proposed test procedures to BUYER for approval at least one month before the scheduled test date.

If the manufacturer proposes to perform the test on the valves together with the actuator in the factory prior to shipment and they can guarantee that the valves are fully functional after delivery, re-testing in Malaysia is not required. However, if the valve complete with actuator is to be tested outside the manufacturer’s factory or premises, testing must be done locally in Malaysia.

6.2 Leak Test

6.2.1 General

Before assembly the leak rate test of the accumulator and 10% of the actuators shall be executed to prove the functionality of the back-up seal arrangements.

The BUYER may waive these tests if compliance with the maximum leak rates is obvious from the nature of design of the back-up seals.

6.2.2                 Leak rate test of actuators

For actuators with a secondary metallic seal the leak rate shall be established with the primary seal removed before assembly. For other than secondary metallic seals the Manufacturer shall propose a test arrangement to simulate a primary seal failure.
