The instrument is designed and made as per the National Standard GB/T4509 “Test Methods for Needle Penetration of Petroleum Asphalt”, and the Industry Standard T0604 “Asphalt Needle Penetration Test”. It is suitable to determine needle penetration of petroleum asphalt and asphalt. The needle penetration of asphalt is expressed as the depth that a standard needle of 100 g vertically penetrates into a asphalt sample without any measurable friction in 5 s at a constant temperature bath of 25±0.1℃.
