1 Scope

This section GB/T 13288 specifies the press ISO 8504-2 given abrasive blast cleaning methods to clean the steel surface roughness now Field assays. This method is used to copy tape and its ancillary gauges on the front surface coating roughness measurements in the field.

This section applies to a given size (or thickness) of the corresponding range replication roughness measuring tape. With a copy of the specifications currently commercially available Roughness measurement range is the average peak height of 20µm ~ 115µm. This section applies to metallic or nonmetallic abrasive blasting to clean up the table after Determination of surface roughness.

3 Terms and Definitions

GB/T 13288.1-2008 and terms and definitions established ISO 4618 applies to GB/T 13288 in this section.

1) GB/T 18839.2-2002 is equivalent to ISO 8504-2:2000.

Principle 4

The surface of the film is a microporous plastic films with copy compressible layer, this layer of thin film coating in an extremely uniform thickness (50µm ± 2µm) of Polyester sheet surface. When subjected to a hard surface extrusion, microporous plastic membrane collapses about 25% of the initial thickness.

Note 1. When the transfer film plated with thin (80nm), the plastic, metal can reflect light, such as indium, the surface can be reproduced by an optical interferometric imaging Meter to test. When copying a similar plastic film coating, a thin layer of metal can be transmitted electrons, such as gold, platinum or palladium, the surface through an electron microscope the study.

Note 2. This test method reflects the "average maximum peak-valley height roughness." Since roughness probe slight translation in a replication surface, instrument the results measured by the average maximum and arithmetic mean different.
