SubscribeImpact Testing and Full Notch Creep Test from Impact Laboratories.
Impact Testing
IMPACT can provide impact testing to a variety of standard test methods.
Charpy impact testing to ISO 179 using a versatile pendulum impact machine capable of temperatures between -100°C and 100°C.
Izod impact testing to ISO 180 over the same temperature range.
Tensile impact testing to ISO 8256.
Puncture impact testing to ISO 6603.
Full Notch Creep Test
The Full Notch Creep Test (ISO 16770) is an accelerated test used to assess the resistance of a polymer to slow crack growth in a chosen environment. A moulded bar is notched on 4 sides and subjected to a static load whilst submerged in a suitable environment. Resistance to crack growth is recorded as time to failure. Test conditions and environments can vary but typical conditions are shown below.
