| INTRODUCTION : |
“NOVA” MAKE SMALL BALL IMPACT TESTER For Decorative Lamination Sheet (As PerIS
2046:1995) is specifically designed for Laboratory Testing of Decorative Lamination Sheet.
Decorative Lamination sheet are normally used for hous
e hold and office furnitur
e, electronic panels etc.
should pusses sufficient strength so
that, it should not crake under th
e effect of impact which they may encounter in every day use.
The ability of Decorative lamination sheets to withstand such impacts may be determine by 2 method.
(A) SMALL DIAMETER BALL IMPACT METHOD.
(B) LARGER DIAMETER BALL IMPACT METHOD. |
| |
In the Small Diameter Ball Impact Method, the sheet
under test is bonded to a 18 to 20mm thick sheet
of particle board and placed over a rigid metallic platform
and impact gun consisting of the indenting ball
and a compress spring is placed in a circular suppo
rting frame place over th
e test sheet and the ball
made to strike it by releasing the spring. The effect of such impacts is
evaluated visually to ascertain the
impact resistant of th e sheet under test.
“NOVA” Small Diameter Ball Impact Testerfor decorative lami nation sheet consist of two part .
(A) A circular supporting plate for holding the impact
hammer perpendicular to
the surface of the sheet made of Mild Steel and a hole in centre to hold impact gun viewing windows & 3 legs for placing it on surface of the sheet under test.
(B) An Impact gun to strike the ball against the surface of the sheets with a none force. |
| |
| OPTIONAL : |
| Support platform made of Mild Steel of size 300 x 300 x 50mm arranged by users or can besupply at an extra cost. |
The Impact gun is made of metal tube and has a ba
ll indenter of 5mm diameter. The indenter can be
pulled back again compression spri
ng with the help of a spring
/
holding device and it will be held in pulled state by a catch cum release lever arrangement.
A release lever is provided to release the ball to en
able it to strike on the sheet under Test. The impact
force can be set by pre compressing the spring and its value his mark on the barrel of the metal tube. |
