Dimensional allowance
1.1 Check dimension a 、 b 、 c of the blocks with steel tape having 1mm
increments. Fine ground face: 0 ~ -2mm, rough ground face +1 ~ - 3mm.
1.2 Paving blocks thickness: 70~150mm, tolerance: +1~ -1mm.

2. Appearance quality
2.1 Squareness
As shown below, stick one edge of a steel square(500×250mm) along the
longer length of the block, measure the gap (e) between the another edge of
the steel square and another face of the block.
Fine machine ground face: e<2mm, rough machine ground face: e<1mm,
joints: e<1mm

2.2 Flatness (“”,“” casting face indication )
2.2.1 Assembly face
Put a 500mm steel ruler along block diagonal line, measure the flatness error (e).
For fine machine ground face: e≤1mm,
For rough machine ground face: e≤2mm.
2.2.2 Non-assembly face
The checking method is the same as to 2.2.1, e ≤3mm.

2.6 Cracks
2.6.1 The net-like cracks are accepted.
2.6.2 If the width of the cracks are ≤1mm , then measure the length of the cracks.
Measure the actual length for the cracks are parallel to the edge and measure the
projected length for the cracks are unparallel to the edge, ( Figure A )
53. 尺寸偏差及外 准观标
Dimension Tolerance & Appearance Inspection
2.6.2.1 A. It is accepted for the cracks located on the surface but
didn’t penetrate to the opposite face and didn’t extend to the edge.
2.6.2.2 B. Penetrating cracks which exceeded the half-length of relative edge
are not accepted.
C. Over-edge cracks which exceeded the half-length of each face are not
accepted.
