LEGO test brick - CoC TEST brick
Logo: Modern logo on the studs.
Material: ABS
Inner ribs: none
Inner tubes: With cross supports
Inner walls: Thin with vertical ridges
Flowrib / center line inside top surface : No.
Mold pip: on the stud.
This photo of a brick with pearl-effect shows a circle around the stud. There is no height difference, this effect seems to be caused by the flow of the material with pearlescent-addition during moulding.
Mold numbers: None. The brick has the letters "CoC" inside.
Our best guess is that CoC stands for Certificate of Conformity.
In order to be legally allowed to sell products, the product has to meet the applicable safety standards. When all standards are met, and the manufacturer can provide proof that they are, the manufacturer can issue a Certificate of Conformity. For this process, tests can be required. It seems like these bricks were made to be used in such tests.
The following parts with TEST on top and CoC inside are
known:
• brick 2x4
• brick 1x2
• plate 2x4.
It seems likely that all are made in one mold.
