Ball-pressure Apparatus

Applicatiion:

Ball-pressure Apparatus is used for testing parts of nonmetallic materials for resistance to heat. It is applicable to electrical equipment,lighting equipment, lowvoltage apparatus, Household electrical appliances, machine tool electrical appliances, motor, electric tools, electronic instruments, electrical instrumentation, information technology equipment, electrical business equipment, electrical fittings and accessories such as electrical and electronic products and its component parts

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

Construction:

·                  ball holder with bore and clamping screw for the bow

·                  Precision5mmpressure ball

·                  Thermocouple for the test stand

·                  Nickel plated steel materials for good thermal stability

Technical Parameters:

Ball Dia.	5mm (R2.5mm)
Total test pressure	20N±0.2N
Samples bearing	Dia.50mm, length100mm, solid stanless steel cylinder
Production of materials	all used stainless steel materials
Remark	Ball pressure instrument takes another a hot bo* (oven) supporting the use.

Conforms to:

IEC 60238, IEC 60309, IEC 60320, IEC 60335, IEC 60598, IEC 60601, IEC 60669, IEC 60670, IEC 60745, IEC 60884, IEC 60950, IEC 60998, IEC 61058, IEC 61558.

Resistance to heat

Self-ballasted lamps shall be sufficiently resistant to heat. E*ternal parts of insulating material providing protection against electric shock, and parts of insulating material retaining live parts in position shall be sufficiently resistant to heat.

Compliance is checked by subjecting the parts to a ball-pressure test by means of the apparatus shown.

The test is made in a heating cabinet at a temperature of (25 ± 5) °C in e*cess of the operating temperature of the relevant part according to clause 9, with a minimum of125 °Cfor parts retaining live parts in position and80 °C* for other parts. The surface of the part to be tested is placed in the horizontal position and a steel ball of5 mmDia. pressed against this surface with a force of 20 N.

The test load and the supporting means are placed within the heating cabinet for a sufficient time to ensure that they have attained the stabilized testing temperature before the test commences.

The part to be tested is placed in the heating cabinet, for a period of 10 min, before the test load is applied.

If the surface under test bends, the part where the ball presses is supported. For this purpose if the test cannot be made on the complete specimen, a suitable part may be cut from it.

The specimen shall be at least 2,5 mmthick, but if such a thickness is not available on the specimen then two or more pieces are placed together.

After 1 hour the ball is removed from the specimen which is then immersed for 10 s in cold water for cooling down to appro*imately room temperature. The Dia. of the impression is measured, and shall not e*ceed2 mm.

In the event of curved surfaces the shorter a*is is measured if the indent is elliptical.

In case of doubt, the depth of the impression is measured and the Dia. calculated using the formula f = 2 p (5 - p) , in which p = depth of impression.

The test is not made on parts of ceramic material.
