Excellent quality and testing ensure conﬁdence
and peace of mind in educational settings.

Free fall impact test

Button durability test

This test considers the forces that a calculator might be subjected to when it is accidentally dropped, such as
off of a desk while the calculator is being used. The calculator is held on both sides by an arm, and is thenreleased at a certain height. The calculator is checked by having it fall onto a block that is intended to simulatea hard ﬂoor.

In this test, a machine is used to press the keys repeatedly to check the durability of the keys during repetitive
operations.

Full-product pressure test

Scratch resistance test

This test considers the kinds of stressors that might be placed on scientiﬁc calculators when they are pressedon by study materials or other external pressures, such as when the calculator is carried inside a bag on theway to school. In this test, both ends of the calculator are secured, and pressure is applied to the central
portion of the device to test its durability.

This test considers the wear that a calculator experiences from repeated use. A number of keys are examined,
such as the number keys, the AC key, and function keys. The calculators are checked for wear by repeatedly
moving them side to side while rubbing them through the use of an abrasive agent deﬁned under Casio’s
internal standards.
