Description

Impact test ball

This sphere is intended to verify the degree of protection of enclosures against ingress of solid foreign objects having a diameter of 12.5/50 mm or greater.
diameter: 12.5mm
handle: with or without handle

Appliance :
This sphere is intended to verify the degree of protection of enclosures against ingress of solid foreign objects having a
diameter of 12.5/50 mm or greater.

In accordance with VDE 0700-69 resp. EN 60335-2-69

Object probe for the ascertainment of protection of persons and for checking the mechanical resistance of the material. With the help of the test sphere the protection of the equipment against intrusive solid particles can be tested. Furthermore the protection of the back of the hand can be rated.

Other sizes and specifications can be customized.

Impact test ball
use method.
Impact energy J = mgH J(Joules)/m(steel ball weight: kg)/g(acceleration of gravity)/H(impact height: m).
For example, a 500g steel ball falls from a height of 1.5 meters,
Impact energy: J = 0.5*9.788*1.5 = 7.341 (Joules)
Note: For pendulum impact, the steel ball needs a ring.

Tempered glass impact pen technical parameters:
The surface is treated with silver chrome plating, the chrome plating layer has a high hardness, and is more durable than the ordinary impact pen.

Chromium plating layer has good heat resistance, heating below 500℃, its luster, hardness are not significantly changed, the friction coefficient of chromium plating layer is small.

The impact pen can impact 3-5mm tempered glass fragments with experimental tip curvature of 0.2mm

Performance: Sharp edge, good feel

Uses: including diamond tools, bronze bit, glass bit, bronze glass bit, glass water slice, drill piece, drill sleeve, chamfer, grinding head, grinding piece, glass chip experiment, etc.

Impactor Type:
There are relevant references in Article 22 of IEC60335-2-24 as follows (quoting the original text of corresponding standard 4706.13)

Test punch – Tungsten steel punch:
The punch mass is 75g±5g, the head and a conical tungsten carbide tip at a 60°±2° Angle, and the glass is broken by hitting the test punch with a hammer.

Tungsten carbide material, surgical instruments commonly used, amazing hardness.
