5.6.8 Specification of soil classes for earth & rock drilling
Class (DIN18300) This class comprises
Class1: Topsoil Top layer of soil containing humus & soil organisms, as well as inorganic material such as
gravel, sand, silt and clay mixtures
Class2: Liquid soil Fluid or pasty soil that tends to retain water
Class3: Soil easy to
excavate
Noncohesive or slightly cohesive sand, gravel and grit, with up to 15% of silt & clay (with a par-
ticle size smaller than 0.06mm (0.002in.)) containing at most 30% of boulders larger than
63mm (2.5in.) each having a maximum volume of 0.01m³* (0.0006in³*); organic soil with lit-
tle water (e.g. strong peat)
Class4: Soil medium
hard to excavate
Mixtures of sand, gravel, silt & clay with more than 15% of their particles smaller than 0.06mm
(0.002in.); cohesive soil with low or medium plasticity, soft to semi-firm according to its water
content , and containing at most 30% of boulders larger than 63mm (2.5in.) each having a
maximum volume of 0.01m³* (0.0006in³*)
Class5: Soil hard to
excavate
Soil of classes 3 & 4, but with more than 30% of boulders larger than 63mm (2.5in.) each
having a maximum volume of 0.01m³* (0.0006in³*); noncohesive or cohesive soil with at most
30% of boulders each having a volume from 0.01to 0.1m³* (0.0006to 0.06in³*); distinctly
plastic clay, from soft to semi-firm, according to its water content
Class6: Rock easy
to excavate & similar
soil
Cemented rock with a mineral matrix but highly fissured, friable, crumbly, soft or weathered, as
well as comparable firm, cohesive or noncehesive soil which may have been strengthened by
drying out, freezing or chemical treatment; noncohesive and cohesive soils with more than
30% of boulders each having a volume from 0.01to 0.1m³* (0.0006to 0.06in³*)
Class7: Rock hard to
excavate
Rock with a strong mineral matrix which is slightly fissured or weathered; strongly bedded, un-
weathered shale, pudding stone, slag heaps from smelting plants, etc.; boulders each having a
volume of more than 0.1m³* (0.006in³*)
*0.01m³ (0.0006in³*) corresponds to a sphere with a diameter of about 0.3m (11.8in.) and 0.1m³ (0.06in³*) corre-
sponds to a sphere with a diameter of about 0.6m (23.6in.)
