This practice2covers procedures for penetrant examina-tion of materials. Penetrant testing is a nondestructive testing method for detecting discontinuities that are open to the surface such as cracks, seams, laps, cold shuts, shrinkage, laminations, through leaks, or lack o.
8 Αυγ 2016 · Type II penetrants with Removal Methods A or C used with Non-aqueous Wet Developers are discussed in this procedure for the detection of surface breaking discontinuities. 2. Referenced Documents.
1.1 This test method covers the measurement of the pen-etration rate of the Dynamic Cone Penetrometer with an 8-kg hammer (8-kg DCP) through undisturbed soil and/or com-pacted materials. The penetration rate may be related to in situ strength such as an estimated in situ CBR (California Bearing Ratio).
Prior to penetrant testing, the surface to be inspected shall be clean and dry. Suitable penetrant is then applied to the test area and enter discontinuities open to the surface. After the appropriate penetration time has elapsed, the excess penetrant is removed from the surface and the developer applied. The
Liquid penetrant processes are non-destructive testing methods for detecting discontinuities that are open to surface. They may be effectively used in the inspection of both ferrous and non-ferrous metals and on non-porous, non-metallic materials, such as ceramics, plastics and glass.
A comprehensive testing program was conducted to evaluate the potential use of the dynamic cone penetrometer (DCP) in the quality control–quality assurance procedure during the construction of pavement layers and embankments.
