Foreword

GB/T 13288 "steel substrates before application of paints and spray cleaned steel surface roughness characteristics" is divided into the following sections.

--- Part 1. Technical requirements for the Assessment of blast - cleaned steel surface roughness of ISO surface profile comparators and definition;

--- Part 2. Determination after abrasive blast cleaning of steel surface roughness comparison specimens class method;

--- Part 3. Calibration and surface roughness measurement method ISO surface roughness comparison specimens microscope focusing method;

--- Part 4. ISO calibration of surface roughness and surface roughness comparison specimens measuring method stylus method;

--- Part 5. Determination of surface roughness Replica tape method.

This section GB/T 13288 Part 3.

1 Scope

This section GB/T 13288 specifies the calibration surface and in line with GB/T 13288.1 requirements of ISO surface profile comparators block Determination of roughness microscope focusing methods.

Roughness measurement. If the surface roughness can not be directly observed, injection should be cleaned on a substrate has a surface area representative or Determination of surface roughness on a copy of the surface (see Appendix E).

Note. In the right place, this assay can also be used to evaluate the surface roughness by the other abrasive blast cleaning of the substrate.

An alternative method, see ISO 8503-4.
