12 months
Rubber and plastic products will be deteriorated gradually by oxidation or influence of heat and sunlight in a long time of use depending on the environment. Moreover, it may not only result in degradation of the necessary performance which was secured in the beginning but also result in a big accident in some cases. Applicable Standard JIS K 6257, ISO 188, JIS K 7212 B Type/JIS K 7212, ISO 4577
Outline
Rubber and plastic products will be deteriorated gradually by oxidation or influence of heat and sunlight in a long time of use depending on the environment. Moreover, it may not only result in degradation of the necessary performance which was secured in the beginning but also result in a big accident in some cases.
The Geer's Aging Oven is a most popular oven to make the sample in the environment where new heated air is always supplied in a constant rate, thus promoting aging.
The series conform to JIS K 6257 (Rubber, vulcanized or thermoplastic - Determination of heat ageing properties) and/or JIS K 7212 (Plastics − Determination of thermal stability of thermoplastics − Oven method). Each of the four models provides different air exchange rate and chamber size. AG-1100 (analog setting) series and AG-1200 (digital setting) series are different in setting method of air exchange rate.
Feature:
○Most important functions like temperature uniformity, wind velocity and air ventilation rate are in accordance with JIS K 6257 and/or JIS K 7212.
○The minimized shape of the series allows use on a table. We also provide with an exclusive stand.
○It is able to place two units in tiers, minimizing the footprint.

GEHMAN’S TORSION TESTER
Rubber loses resiliency as temperature goes down. The frozen rubber can't keep its essential characteristics under the temperature below Glass Transition Point. In fact, the rubber applications under severe environments such as vehicle tire in frozen area and aircraft components in the stratosphere are seriously affected. Our Gehman's torsion tester TM-2535 is the most popular testing machine for this purpose and is adopted by JIS K6261(Equivalent to ISO 1432, ASTM D1053).
DIN Abrasion Tester
The DIN Abrasion Tester is of the type that rotates a drum with grinding cloth wound around the surface at a specified speed, presses the sample against the grinding cloth. Applicable Standard: JIS K 6254-2/ISO4649/ISO23794 Test Piece Size: 16.2±0.2mm dia, 6mm or thicker Drum Size: 150±0.2mm dia., 460mm wide Drum Speed: 40±1rpm
