Frequently Asked Questions (FAQs)

Who at EASA is our contact for questions regarding this program?

电子邮件询问: accreditation@www.barefoot-u.com

Are there levels of accreditation?

Do new instruments need to be calibrated?

Do the inside micrometers need to be calibrated?

一些服务中心不校准内径千分尺，因为他们把内径千分尺放在孔里并设置它, 然后把它滑出来，用一个校准过的外径千分尺来测量内径千分尺. Is this an acceptable practice? If so, do the inside micrometers need to be calibrated?

Using the inside micrometers as gauges, 使用外径千分尺进行实际测量是可以接受的做法. The inside micrometers should be identified as “for reference only”; and the outside micrometers must be calibrated.

Additional information regarding equipment calibration.

Can we calibrate our own meters?

需要进行磁芯损耗测试的电机额定功率范围是什么?

What does the QR code on the label do?

Do all bearings have to be cut during regular inspection process?

该程序只适用于三相交流电机，还是也适用于直流电机?

A motor is received for for cleaning and changing bearings. Winding tests indicate the winding is satisfactory. 然而，它以前已被重绕，可以维修认可?

作出这一决定的主要判断标准是测试的结果, and observation of the winding. The key test is the no load test, 空载电流是可接受性的主要指标. 如果空载电流在合理范围内，则判定绕组数据为可接受的(参见检查表项目18空载测试.)也, by observation if the slot fill is normal, 这是, 不低, the wire area per amp should be acceptable. If both the test and observation criteria are met, the winding can be judged acceptable for an accredited repair.

Is a spectrum analyzer required for vibration testing?

当AR100发生变更时，认可的服务中心需要多长时间才能合规?

There will be a 1-year grace period following the publishing date of a revised edition of AR100; which would be sufficient time for both auditors and accredited service centers to implement any changes necessary to conform to the revised edition. 进一步, 如果在AR100中出现了需要更长的时间来实现的变更, that would be dealt with on a case by case basis.

How many thermocouples does our burn off oven need?

Is part temperature sensing required for the bake oven?

Is there particular information that’s required to be documented?

有一项要求是“保持认证标签、序列号和放置它们的电机的记录.” Is there particular information that’s required to be documented? Is there a reporting requirement for the information?

The specific text on this topic is given in the program terms and conditions as:

“被认可的公司必须保留一份标有相应标签和服务中心工作编号的马达清单. 至少，每个认可维修的清单必须包括标签编号和服务中心工作编号. Additional information about the repaired motor, 如制造商, 额定功率, 速度, 序列号, 等. can be included in the listing, but is not required."

我们有客户经常把没有接线盒的电机送去维修. Is this motor eligible for an Accredited repair?

带正弦波滤波器的变频器可以作为电机测试面板上的电源吗?

我们的服务中心使用带正弦波滤波器的变频器作为电机测试面板的电源. It also has readouts for phase voltage and current. 这是否满足EASA认证关于测试面板的要求?

Based on the 认证 Checklist and AR100 clause 4.5、电机需在额定电压和频率下试验运行. 因此，只要测试运行满足这些要求，VFD的使用是可以接受的. 使用正弦波滤波器是有益的，因为测试结果应该与那些如果和当电机从公用电源操作. 电机的电压和电流应该在测试面板的输出和电机之间的某处测量.
