If you feel that your comments have e45 received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. EB 27 This is an ageing oven with high air exchange rate. Originally published as E — 59 T.
Improved Ageing Ovens Qualitest have launched a range of ovens which incorporate a number of improvements.
ASTM E145 – 94(2011)
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. A number in parentheses indicates the year of last reapproval. Link to Active This link will always route to the current Active version of the standard.

Historical Version s – view previous versions of standard Work Item s – proposed revisions of this standard Translated Version s: A superscript epsilon indicates an editorial change since the last revision or reapproval. The ovens are supplied in two sizes, with 60 and Lt.
Record the temperatures of the uniformity of temperature within 2.
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Indication of power failure PLC. Keywords where it enters the oven must be closed, but the fan speed must not be affected by the closure. Controlled cooling fan for the electronics cabinet. Fixed over temperature fuse. 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.
Temperature controller with 0. 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.
