Summary
This instrument is designed and made as per T********3 Flash Point
Determination for Liquid Asphalt by Tag Method in JTG E******1
Standard Test Methods for Bitumen
and Bituminous Mixtures for Highway Engineering. It is used
to test the liquid asphalt which flash point is lower than
*3℃.
Main technical features
1.It adopts a special liquid heating system to heat the sample. It
can ensure the safety of test. The heating power can be adjusted
continuously.
2.Desktop structure. Stainless steel working bench and outer shell
of heating furnace.
3.All parts are ready. User can do test as long as equipping civil
gas and other natural gas.
Main technical specifications
1. Power supply: AC（**0±*0%）V, *0Hz.
2. Sample cup: Metal crucible, *7mm in depth，Ф*4mm in upper
mouth diameter，Ф*8mm in lower mouth diameter. There is a scale
line at a distance of 3.2 from upper edge.
3. Heat preservation liquid cup: 0.3 high quality carbon structure
steel. Inner diameter of upper mouth is Φ**0mm±5mm; The height is
(*0±5)mm, Inner diameter of bottom
is Φ*6mm±2mm.
4. Igniter: It is composed of gas inlet pipe, flow rate adjusting
valve and flame comparing ball. The diameter of spout is
Ф0.7mm～0.8mm, Operator can adjust the flame to a ball with
diameter 4mm.
5. Sample heat: The liquid heating system is composed of heating
furnace, heat preservation liquid cup and sample cup. It can
control the heating rate by heat regulator as per
requirements.
