Pressure Aging Vessel

For accelerated aging (oxidation) of asphalt binders by means of pressurized air and elevated temperature. This is intended to simulate the type of changes which occur in asphalt binders during in-service oxidative aging but may not accurately simulate the relative rates of aging. It is intended for use with residue from Test Method D2872 (RTFOT) which is designed to simulate plant aging. Conforms to ASTM D6521, AASHTO R28, EN14769 Conforms to the specifications of: ASTM D6521; AASHTO R28; EN14769 Operating Pressure: 2.10 ± 0.05 MPa (304 psi) Temperature Range: 90°C to 110°C (194°F to 230°F) Temperature Control Resolution: ± 0.1°C Test Temperature Uniformity: ± 0.5°C Time to Set point: 3 hours from ambient Return to Set point: 120 min. after preheating and loading of specimens Pressure Vessel: ASME code section VIII, division 1; 1992 A 93 Maximum Pressure: 325 psi (2.24 MPa) at 120°C (250°F) Pressure Safety Release: 325 psi (2.24 MPa) 230V 50/60Hz K88100-1 UPS Battery Backup System K88100-2 PAV Verification Kit K88100-3 PAV O-Ring K88100-4 CGA Adapter
