Care & Maintenance - Elcometer 4270 Guide D'utilisation

3 TEST PROCEDURE (continued)
6 Lift the sag tester from the substrate taking care to catch any
product dripping from the sag tester before it lands on the newly
prepared film.
7 Immediately place the substrate in a vertical position with the
thinnest strip at the top. The thickness at which the strips join
indicates the tendency of the coating to sag.
3.2 AFTER TEST
Clean the sag tester using a suitable solvent.
DO NOT use very aggressive solvents, wire brushes, metal
scrapers, metal files or other metallic tools for cleaning.
After cleaning, ensure that all materials are removed and that the sag
tester is dry.
Use the case provided to store the sag tester when not in use.
4 CARE & MAINTENANCE
The Elcometer 4270 is designed to give many years reliable service
under normal operating conditions.
Regularly inspect the sag tester for damage to the working surfaces as
this will affect the film thickness and the sag tester may have to be
replaced.
Regular calibration checks over the life of the sag tester are a
requirement of quality management procedures e.g. ISO 9000 and
other standards.
