Compliance Standards:

ASTM D402, IS 1213, IP 27, AASHTO T78

Scope:

This apparatus is used for the examination of cut-back asphaltic materials by the distillation test.

Consists of following parts and accessories:

1) Distillation Flask

1. Capacity         : 500mL
2. Type            : Side-arm type having the dimensions shown in Fig. 1 of ASTM D402.

2) Condenser

1. Type             : Standard glass-jacketed,
2. Length            : 200 to 300 mm
3. Overall tube length  : 450 ± 10 mm

3) Electric heater with Digital Temperature controller

Electric heater with Microprocessor based AUTO-TUNE PID Digital temperature controller cum indicator with PT-100 Sensor.

4) Adopter

Heavy-wall (1-mm) glass, with reinforced top, having an angle of approximately 105°. The inside diameter at the large end will be approximately 18 mm, and at the small end, not less than 5 mm. The lower surface of the adapter will be on a smooth descending curve from the larger end to the smaller.

4) Shield

Lined with 3-mm fire proof insulation and fitted with transparent mica windows, of the form and dimensions shown in Fig. 2 of ASTM D402. It is used to protect the flask from air currents and to reduce radiation. The cover (top) will be made in two parts of 6.4-mm (1⁄4-in) fire proof insulation.
