Internal Inspection Guideline for Heater 取暖器验货指南(For products destined to US only)Revision date: July 8, 2004 1. 检查要点 2. 特定的检查点和测试项目 （电暖器适用） 3. 特定的检查点和测试项目 （煤油取暖器适用） 4. 特定的检查点和测试项目 （煤气取暖器适用） 1. 检查要点 Packaging, Content, Cosmetic, Construction, (above 4 items please kindly refer to general item guidelines), Special checkpoint test, please see below for details. 包装，内容，外观，结构，（以上四项请参考通用验货指南），特定的检查点和测试项目，以下详述。 2. 特定的检查点和测试项目 （电暖器适用）-1 Dielectric voltage withstand test: product shall withstand 1000v for 1min or 1200 v for 1sec test (heater rated voltage: 0-250v) across the live parts to accessible metal or plastic parts. Result is that no any parts were breakdown. (cut-off current setting on Hi-Pot Tester should less than 100A,initial setting 0.5~5A was recommended) 高压抵挡测试：对于额定电压为0－250v的取暖器，1000v电压一分钟或1200v一秒钟加在带电部件与可接触的金属或塑胶件之间，不应该被击穿。(高压机截止电流设置应小于100MA,推荐初始设置为0.5~5MA) 2. 特定的检查点和测试项目 （电暖器适用）-2 Leakage current test: all exposed conductive surfaces to be tested, the test result shall not more than 0.75mA for non-movable items or 0.5mA for movable items. 泄漏电流测试：所有外露的导电面均需测试，测试结果不应超出0.75mA(非活动式取暖器)或0.5mA(可移动式取暖器)。 2. 特定的检查点和测试项目 （电暖器适用）-3 Grounding continuity test (if units assembled with earth wire): with a current 25A derived from a 60HZ source with a voltage not exceeding 12v is passed between the grounding connection and the metal parts, test result must be less than 0.1ohm. Alternative: use multi-meter, resistance close to “Zero” 接地连贯性测试（如果产品装有地线）： 25A，60Hz，不超过12V的电压加在地线和 金属件之间，测试结果必须小于0.1欧。可以用万用表来测量, 电阻值接近于零 2. 特定的检查点和测试项目 （电暖器适用）-4 Strain relief test: power cord shall withstand a weight of 35 lbs (15.9 kgs) pull test for one minute, power cord no any displacement / movement. (The inside connection point is the check point and no force allowed to pull on it) 电源线拉力测试：电源线应该能够经受一分钟35lbs(15.9kgs)的拉力，电源线不应该有任何移动或移位.(判定标准为内部铜线接线点不允许有受力引起位移) 2. 特定的检查点和测试项目 （电暖器适用）-5 Switch operation test: shall operate smoothly 20 times consecutively. 开关可靠性测试：连
