IEC60695-10-2:2014 Ball Pressure Tester / Stainless Steel / 2.4kg

IEC60695-10-2:2014 Ball Pressure Tester

Overview:

The device is a special instrument designed and manufactured according to the requirements of the relevant standard provisions of the ball pressure test, which is used to test the heat resistance of non-metallic materials. Suitable for electrical equipment and its components and parts, non-ceramic solid electrical insulation materials and other non-metallic material heat resistance test.

Technical parameters:

1, spherical head load: 20N±0.2N

2, indenter steel ball: bearing steel R2.5mm (diameter: 5mm)

3, Material: 304 stainless steel

4, test temperature: 60℃±2℃

5, overall size: 420mm×150mm×60mm

6. Net weight: 4.2Kg

Standard:

GB4706, GB2099, JG/T3050 "Insulation electrical conduit and accessories for construction", etc.

IEC60695-10-2:2003 "Abnormal thermo -Ball pressure test" standard specified thermoplastic material resistance to thermal deformation caused by abnormal heat simulation test project

Balance check:

The pressure ball is placed on the support, and the position of the load body is adjusted appropriately according to its swing, and then the load body is tightened, the pressure ball is placed on the support again, and the swing situation is observed to determine the adjustment effect.

Only in the case of balance, the pressure ball can be placed smoothly, otherwise the pressure ball will swing significantly, if detected by optical equipment, it will seriously affect the accuracy of the test results.

Test method:

Hard casing and accessories take three 80mm long casing, cut it into two pieces along the casing axis, and take one piece of each as the sample. Accessories may be made from accessories as appropriate.

Put the sample and the heat resistance tester together in the oven with a temperature of 60℃±2℃, put the sample on the plate of the heat resistance tester, place the conical object with a diameter of 5mm at the lower end on the sample, and keep it for 1h under the action of 20N pressure (for the sleeve, it should be pressed on its concave surface), and take out the sample after reaching the specified time. After cooling at room temperature, determine the indentation diameter with a vernier caliper, and its value should not be greater than 2mm, to evaluate the thermal deformation ability of the test product at the specified temperature

Maintenance

1. R2.5 steel ball is bearing steel, pay attention to rust prevention.

2. Keep the end face of the support smooth and smooth.

3. Prevent foreign matter from blocking the 2.5 thermocouple hole.

4, to prevent the weight screw loosening.
