IEC60884-1 figure 40 Apparatus for Testing Resistance to Abnormal Heat of Insulating Sleeves of Plug Pins
1. Introduction
Apparatus for testing resistance to abnormal heat of insulating sleeves is designed according to IEC6884-1 figure 40 and clause 28.1.2, the test apparatus consists of an insulating plate A and of a metal part B to verify the insulating sleeves of plug pin resistance to abnormal heating.
The specimens are inserted in the test apparatus, and placed in the most unfavourable horizontal position, when the test apparatus has reached a steady temperature and maintained for 3h, the specimen are then taken out from the test apparatus and are allowed to cool down to room temperature, the insulating sleeves of the pins of the specimens are then submitted to an impact test at ambient temperature, and subject to visual inspection, the insulating sleeves should be shown no cracks by visible with normal or corrected vision without additional magnification, and the dimensions of the insulating sleeves should not have changed.

4. Frequently Asked Questions
1). Will you provide the on-site installation service?
Pego: Actually, the equipment will no need on-site installation service. The equipment will be shipped almost as a whole, user just need to make simple wiring connection when receive the goods.
2). What is the warranty period? and how can we get the after-sales service?
Pego: The warranty period is 12 months upon user receive the goods. 95% of after-sales problems can be solved by our engineer team through remote service. Customers will get a response within 24 hours in business day after reporting the problem. In our experience, most of the troublesome can be removed with the guidance of our engineer, only a small part of the troublesome are caused by parts failure, that is because we use the branded components, which have better performance and good reliability. If the parts damaged, we will a send a new for replace, the new parts will be charged for free within the warranty period. And also our eigneer team will teach how to replace the damaged parts.
3). Will the device come with test report?
Pego: Yes, the equipment can come with factory test report for free. But if you want the calibration certificate issued by an ISO17025 authorized laboratory, the calibration cost will be charged additionally, and lead time will be extended.
