1 ABOUT YOUR TESTERThe Elcometer 1500 Cylindrical Mandrels and Stand is a simple-to-use instrument for determining theelasticity, adhesion and elongation of dried paint on sheet metal.
The instrument includes a set of mandrels of different diameters which allow the point at which coating
failure occurs to be determined. The mandrels are stored in a stand which also serves as a holder for amandrel during the test.
A mandrel is placed in a vee groove on the top of the stand and the metal test panel is bent by hand overthe mandrel.
The test panel is then assessed visually to determine the bending characteristics of the coating.

2 TESTING A SPECIMEN
Use the test procedure described in the standard to which you are testing. If no standard is specified, follow
the instructions below.
1. Place the tester on a sturdy table.
2. Select the largest mandrel and place the mandrel into the vee grooves at the top of the stand.
3. Place a test panel over the mandrel with the uncoated side in contact with the mandrel.
4. Using finger pressure, bend the test panel approximately 180° around the mandrel in a single smoothaction taking 1 to 2 seconds.

5. Remove the test panel from the mandrel and inspect the coating for damage.

6. If the coating is not damaged, take a new test panel, select the next smallest mandrel in the set1, andrepeat steps 2 to 5 until the smallest mandrel which produces no damage to the coating is determined.
7. If required, calculate the total elongation:
If the coating is 25 µm (1 mil) thick, use Table 1 to determine elongation. Table 1 gives the elongationof a 25 µm (1 mil) thick coating on 0.8 mm (1/32") cold-rolled steel.

4 MAINTENANCE
The Elcometer 1500 Cylindrical Mandrels and Stand is designed to give many years reliable service undernormal operating and storage conditions.
During use, ensure that you do not try to bend very thick test panels on the smaller mandrels; this can cause
the mandrels to become bent.
Avoid contact with highly corrosive substances.
The tester does not contain any user-serviceable components. In the unlikely event of a fault, the Elcometer
1500 should be returned to your local Elcometer supplier or directly to Elcometer.
