BS 1363 Figure 24 - Ball Pressure Test

IEC60335 Flammability Ball Pressure Gauge Tester for which made of stainless steel

1. Introduction: 

Ball pressure tester is used for testing parts of non-metallic materials for resistance to heat. It is applicable to electrotechnical equipment, its subassemblies and components, and to solid electrical insulating materials except ceramics. 

In this test, a conditioned specimen is placed on a preheated support and subjected to a force of 20n applied through a 5 mm steel ball. The test stand, specimen and loading device are then kept in an oven at an elevated temperture for an hour. After the hour, the loading device is removed from the sample, the sample is cooled and any indentation is measured. It is important to assure that the test stand has reached a stale elevated temperature as required by the test. For this reason, the SFT ball pressure tester comes equipped with a thermocouple that inserts into the test stand so its temperature can be monitored.

2. Application: 

Ball Pressure Apparatus/Tester is the requirement ball (R2.5mm) and total test force 20N ± 0.2N ball pressure testing device, pressure level of the state and was placed in the heating chamber on the surface of the test. 

In the test temperature specified by the after 60min +2 min/0min, the test quickly (<10s) immersed in 20 ° C ± 5 ° C water cooling 6min ± 2min, 3min removed from the water surface within the indentation diameter measurement test, as the indentation is more than 2mm in diameter to evaluate the test specified in the heat deformation temperature. 

Remark: Ball Pressure Instrument takes another a hot box (oven) supporting the use  

Construction:

• Ball holder with bore and clamping screw for the bow
• Precision 5mm pressure ball
• Thermocouple for the test stand
• Nickel plated steel materials for good thermal stability
