BS 1377:4 | BS 1924:2 | EN 13286-4 | NZS 4402.4.1.3:1986 | NZTA T19:2020
Mainly used for the vibrating hammer compaction test, but can also be used for the compaction of soil specimens and NZTA T19 basecourse specimens.

Using the appropriate tamping foot it can also be used for compacting asphalt in the “Percentage refusal density test”.

Double insulated motor. Plastic trigger handle. The hammer is supplied without support frame and tampers which have to be ordered separately.
