Details
The Anderen Impact Test Hammer or edge chipper is now available with a dual scale for carrying out impact tests according to A.S.T.M. ceramic test method C 368, one scale for bone china domestic tableware, and the other for carrying out tests on more robust ware (e.g hotelware).
The impact tests are carried out on either glazed or unglazed samples at the centre of both flatware and hollow ware, at the rim of hollow ware, and edge chipping tests at the rim of flatware.
The tests at the centre of the of the specimen are carried out to determine: (a) the magnitude of a blow that will be required to produce and initial fracture and (b) the amount of energy necessary to produce complete failure.
The impact test at the rim of hollow ware is similar to a chipping test, and the type of failure that is obtained is useful in evaluating the effect of the shape of the object.
The edge chipper can be used to test hollow ware and also cup handle strength
The instrument is supplied with a 4ounce and 6 ounce hardened steel hammer and a centre impact adapter
The Standard Anderen Impact Tester can accommodate plates with diameters up to 12" (30cm)
However we offer customised units that can accomodate samples with diameters up to 20" (50cm)
