Product Description

I.Summary
1.The instrument is designed and made as per the National Standard of People's Republic of China GB/T***9 “Test Methods for Penetration of Asphalt”, and T***4 “Asphalt Penetration Test” in the Industry Standard of People’s Republic of China JTJ*******0 Specification and Test Methods of Bitumen and Bituminous Mixture for Highway Engineering.
  2.The instrument is suitable to determine the penetration of asphalt, modified asphalt, and residue of liquid asphalt or emulsified asphalt after evaporation. The standard testing condition is described as follows:
3.The penetration of asphalt is expressed as the depth that a standard needle of **0g±0.*5g vertically penetrates into an asphalt sample in a constant temperature bath of *5 ℃±0.1 ℃ in 5 s without obvious friction. The greater the penetration is, the less the consistency of asphalt is, and the softer the asphalt is.
4.It can also be used to make inspection for solid granule, powder, colloid, freezing substance and other materials, as well as cheese, glycine, butter, cream, fermentation, and other food materials. It can be widely used in the food industry, traffic and transportation industry, and other industrial industries.
