Each comparator shall be accompanied by a calibration certificate stating the method for determining the surface profile, the estimated tolerance, and the calibrated surface profile, in micrometres, of each segment see also clause 8.

Irrespective of the procedures and the type of abrasive that are used for the preparation of steel substrates, the surface after blast-cleaning consists of random irregularities with peaks and valleys that are not easily characterized.

This will be indicated in the amendment table on the inside front cover. Surface and its parameters. Characteristics of the roughness of blast-cleaned surfaces are defined in 3. It presents the UK view on standards in Europe and at the international level.

Consequently, it was concluded that, because of this random nature, no method is capable of giving a precise value for the profile. This does not preclude the free use, in the course of implementing the standard, of necessary details such as symbols, and size, type or grade designations. NOTE Comparators in frequent use should be checked against an unused comparator at three-monthly intervals or whenever the surface appears worn 853-4 damaged.

The determination can be carried out on a representative section of the blast-cleaned surface or, if direct observation of the surface is not feasible, on a replica of the surface. A British Standard does not purport to include all the necessary provisions of a contract.
