Specifications include, but are not limited to: 1) Shall be a forced air ignition furnace capable of maintaining a temperature of 6500 C (1200 0 F). Shall also be capable of maintaining other set temperatures. 2) Shall be equipped with an internal balance, thermally isolated from the furnace chamber, capable of weighing a 5000-gram sample in addition to the sample basket. Endpoint sensitivity must be within 0.01%-0.5% of sample weight. 3) Shall calculate a temperature compensation factor for the change in weight of the sample baskets and provide for positive or negative input of aggregate calibration factor. 4) Shall provide printed results that include: initial specimen weight, specimen weight loss, temperature compensation, correction factor, corrected asphalt content in percent, test time and test temperature. 5) Shall have a minimum sample chamber of 355 x 266 x 355mm (14" x 14” x 14") (W x H x D). 6) Sample stability is reached once endpoint criterion is met for 3 consecutive minutes during the test. 7) Shall have automatic endpoint detection within 0.01% and software ends the test, prints the results and beeps until STOP is pressed to unlock door. 8) Shall have a safety door lock that prevents access during operation. 10) Shall be equipped with a 24 hour/7day timer. 11) Shall be capable of accommodating samples of up to 5000 grams. 12) Shall operate on 208 volt power. 13) Shall have convection heating. 14) Must utilize a ceramic filter used in conjunction with a high temperature afterburner to reduce the emissions created during the ignition test by 95%. 15) Must have a published study showing the results of a quantitative emissions study conducted in cooperation with the California EPA and OSHA. 16) Must have five independent, hard refractory, embedded heating elements. 17) Must have the ability to accept “positive” and “negative” aggregate calibration factors.
