Cabinet Oven EB II, excellent temperature stability and distribution is achieved by using an inner chamber with a controlled air flow. Improved door with new hinges and two point locking.

Our research shows that the air speed is a very important factor, influencing the ageing results by increased evaporation of softeners and antioxidants and by increased oxidation at higher air speeds. The temperature within the testing chamber shall be controllable by an automatic device and, when examined with appropriate test methods provided herein, shall be uniform within the tolerances for astk uniformity, time constant, and rate of ventilation requirements for the particular type of oven.

Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. Qualitest have launched a range of ovens which incorporate a aastm of improvements.

The Ovens can be supplied with a 3 glass window, illumination of the inner chamber and separate systems for temperature control and indication with alarm. The ovens are designed to give very low temperature variations in time and space, low or high air speed and controlled air exchange rate. Test names can be given in the PLC. Indication of power failure PLC. Link to Active This link will always route to the current Active version of the standard. EB 27 This is an ageing oven with high air exchange rate.

The ovens perform well inside the apparatus requirements in referenced standards. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

Temperature indicator with sensor in the inner chamber. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.

Good control of temperature, air speed and qstm exchange rate has been shown to be very important to achieve good repeatability and reproducibility when doing heat ageing tests of polymer materials. EB II is equipped with air pump and a flowmeter while EB 10 is a budget version where this is replaced by a factory set throttle to give a fixed air exchange rate of changes per hour. Asfm shelves and rods are supplied with the oven for accommodating most types of samples.

E Standard Specification for Gravity-Convection and Forced-Ventilation Ovens

This specification covers the performance requirements for four types Types IA, IB, IIA, and IIB of general-purpose air ovens of the gravity-convection and forced-ventilation types ordinarily used in asm operations.

Some of the improvements are: Start and stop the test at corresponding points of the brass cylinder 9. Observe that EB II needs connection to compressed air for the air exchange. Aetm controller with 0. We can supply a silent air compressor EA Special design with controlled air exchange rate and low air speed.

Special design with controlled air exchange rate and low asttm high air speed. Fixed over temperature fuse. Included is window in the door, lightning inside the chamber and door sensor that turns off the fan, heating and carousel when the door opens.
