DuPont Impact Testing Machine

A. Product introduction:

Introduction to the use of the DuPont impact testing machine for plastics: Place the test piece with the coated surface facing up, place it on the test impact point, drop the weight freely from a certain height, and check the damage and deformation after the impact. Used for testing adhesion of plastic ceramics, acrylic, fiberglass, etc. and coatings.

B. Reference standards:

DuPont impact tester standard basis: JIS-K5400, K5640, ASTM-D2794

C. Technical parameters:

• Applicable materials for coating DuPont impact testing machine:

• Coating test piece/plastic test piece

• Drop height (optional): 50~500mm, interval 5mm;

• 50~1000mm , interval 50mm

• Weight : 300, 500, 1000 (g) (or customized) ;

• Impact hammer radius: 1/2, 1/4, 3/16, 1/8, 1/16 (optional) (inch)

• Impact seat radius: 1/2, 1/4, 3/16, 5/16, 1/8, 1/16 (inch) 1mm, 15mm (optional)

• Volume : (W*D*H):58*30*82cm;/58*45*128cm

• Weight : about 45kg;/about 60kg

D. DuPont impact tester operation steps:

1. Prepare the sample:

• Determine the size of the specimen according to the spacing between the fixtures (as required by the test).

• DuPont impact tester sample installation: Place the sample in the center of the impact seat.

• Adjust the required test height according to the test requirements (the height interval is 50mm). Insert the fixing fork into the hole.

• Select the weight, place it on the fixed fork, enter the test, take out the fixed fork with force, the weight falls and impacts the impact head, and the impact head impacts the test piece.

2. Determination of coating DuPont impact tester results:

• Remove the sample and observe the damage.

• Impact energy E (kg-m) = weight (kg) ´impact height (m)2

• ※ 1kg-m=9.80665N
