Grinding Wheel Safety Tests IMA Abrasives oSa certificates are carried out by industry experts.
To be certified oSa, our products must pass compliance and safety tests.
Safe abrasives must be able to withstand the forces and loads that can be expected under both normal conditions of use and in the event of improper use. Resistance to deformation and bursting depends on various factors such as material, geometry, type and duration of stress and environmental conditions.
There EN 12413 standard requires that cutting and grinding discs have sufficient bending and impact resistance, determined by the lateral load test and the impact test. In addition to a centrifugal force resistance factor, verified by the burst test (destructive test).
The lateral load test is performed on both cutting discs and grinding wheels.The abrasive disc is subjected to pressure with an appropriate lateral load, while rotating at maximum operating speed.. If the grinding wheels reach the required value without breaking, the single point lateral load verification is considered to be provided. Grinding wheels used for the test shall be destroyed.
In the impact test, the resistance to a lateral impact load, similar to a shock, is determined. The grinding wheel to be tested is fixed on a rotating spindle by means of flanges and then accelerated to its maximum operating speed. The rotating grinding wheel is then loaded laterally with one or more successive impacts, until it breaks. Verification of the working capacity is considered to have been achieved if no damage is visible to the naked eye at the required value.
When you buy an abrasive disc, you make a SAFE choice. Choose the abrasive wheels made in Italy by IMA Abrasivi.
SAFETY TESTS FOR oSa-CERTIFIED IMA ABRASIVE WHEELS
Tests for the safety of oSa-certified IMA Abrasives grinding wheels are carried out by industry experts.
To be oSa certified, our products must pass conformity and safety tests.
Safe abrasives must be able to withstand the forces and loads that can be expected in both normal conditions of use and in the event of misuse. Resistance to deformation and bursting depends on various factors such as material, geometry, type and duration of stress and environmental conditions.
EN 12413 regulation requires abrasive cutting and grinding discs to have sufficient resistance to bending and impact, as determined by the side load test and the impact test. In addition, they should be able to resist centrifugal force, verified by the bursting test (destructive test). The single-point side-load test is performed on both cutting discs and grinding wheels. The grinding disc rotates at maximum operating speed. If the grinding discs reach the required value without breaking, it means that they have passed the test. The grinding wheels used for the test must be destroyed.
In the impact test, on the other hand, the resistance to a side impact load, similar to a shock, is determined. The wheel to be tested is fixed on a rotating spindle by means of flanges and then accelerated to its maximum operating speed. The rotating grinding wheel is then side-loaded with one or more subsequent impacts, until it breaks. Verification of the working capacity is considered to be OK if no damage is visible to the naked eye at the required assessment
