4.0 GENERAL REQUIREMENTS一般要求:
0.
(D) 4.1 ALL BONNET BUSHINGS AND BODY SEAT RINGS SHOULD BE EXAMINED BY LIQUID PENETRANTS BEFORE BEING ASSEMBLED (OR PNEUMATICALLY TESTED ON BODY SEAT RINGS).
所有上密封衬套和阀体阀座圈在装配前都必须做液体渗透测试（着）。
4.2 THE VALVES SHOULD HAVE A PRESSURE-FREE OPERATION TEST IN ORDER TO MAKE SURE THAT THEY OPERATE ADEQUATELY, FROM COMPLETELY OPEN TO COMPLETELY CLOSED AND VICE VERSA.
阀门必须进行一个压力释放操作测试以确保所有阀门从完全开启到完全关闭状态时能充
分的运作，反之亦然。
中国现代医学杂志(C) 4.3 THE FORCE THAT SHOULD BE APPLIED IN ORDER TO COMPLETELY OPEN OR CLOSE THE VALVE HAS TO BE OF A PERSON UNDER NORMAL CONDITIONS.
确保一个人能在正常情况下完全开启和完全关闭阀门。
4.4 THE PRESSURE PIPE, TESTING BENCHES, TESTERS, CONNECTIONS AND TESTING EQUIPMENT SHOULD BE APPROPRIATE TO THEIR PURPOSE. THE PRESSURE GAUGES SHOUD HAVE THE RANGE INDICATED IN TABLE 10.
压力管道，测试椅，实验装置，链接盘和检测设备等都必须符合规定。压力表需在表10所述范围之内。
4.5 ALL VALVES SHOULD BE TESTED AND EVERY VALVE SHOULD BE SUBMITTED TO THE TESTS INDICATED BY THIS SPECIFICATION UNLESS OTHERWISE SPECIFI
ED BY THE PRODUCT ENGINEERING DEPARTMENT OR SPECIFIC CUSTOMER REQUIREMENTS.
所有阀门都必须经过测试且所有阀门都必须根据此规范提交测试，除非有相关的产品工程部门的说明或客户明确的要求方可免除测试。
4.6 THE VALVES BEING INSPECTED MUST BE SUBMITTED TO THE TESTS INDICATED BY THIS SPECIFICATION, RESPECTING THE ORDER INDICATED.
所有阀门需依照规范要求或订单要求提交检验。
高粱秸4.7 UPON CARRYING OUT PRESSURE TESTS ON THE VALVES COVERED UNDER THIS SPECIFICATION THEY SHOULD NOT BE PAINTED. IF FOR SOME REASON IT IS REQUIRED TO TEST VALVES FOUND IN THE FINISHED PRODUCT WAREHOUSE, THEY CAN BE INSPECTED AGAIN WITHOUT REMOVING THE PAINT.
执行压力测试的阀门必须是未油漆的，若由于某种原因需要对成品进行检测的，可在未除掉油漆的情况下进行。
4.8 陈映真 THE TIMES INDICATED WITHIN THIS SPECIFICATION FOR THE DIFFERENT TESTS SHOULD BE INSPECTED FROM THE TIME THE VALVE IS PRESSURIZED TO THE CORRESPONDING PRESSURE RANGE AND IS FOUND TO BE STABLE .
规范中规定的每一次不同的试压方式都要进行阀门检验，且遵照相应的表格内容和
试压范围。
4.9 WATER TEST REQUIREMENTS 水压测试要求
4.9.1 THE TEST WATER SHOULD CONTAIN AN INAX (PROVIDER: TURCO AND DESCALSY) RUST INHIBITOR OR EQUIVALENT. THE TEST WATER SHOULD HAVE A PROPORTION OF 7 TO 8 GRAMS OF RUST INHIBITOR PER LITER OF WATER. THE RUST VISCOSITY OF THE WATER INHIBITOR COMBINATION SHOULD NOT BE GREATER THAN THE WATER VISCOSITY. THE WATER INHIBITOR-RUST PROPORTION SHOULD BE INSPECTED EACH WEEK.
用于水压测试的水需含有防锈剂，每公升水需含有7-8克的防锈剂。水中铁锈的浓度不得大于水中防锈剂的浓度，水中的防锈剂—铁锈比例需每周检测一次。
4.9.2 CONTROL THE HALOGEN CONTENT TO THE FOLLOWING AMOUNT:
控制以下元素的总含量：
CHLORINE 30.00 P.P.M. MAXIMUM
氯： 最大30.00 PPM
FLUORINE 00.75 P.P.M. MAXIMUM
氟：最大 00.75 PPM
4.9.3 THE TESTS SHOULD BE CARRIED OUT AT ROOM TEMPERATURE MAKING SURE THAT THE TEST FLUID TEMPERATURE DOES NOT EXCEED 52 °C (125°F).
