Modern surface texture measuring instruments record the stylus movement over the evaluation length electronically and can produce output readings to a significant level of detail.

These are different depending on the standard used and on surfacf issue of the relevant standard. Your basket is empty. Use this information at your own risk.

The total roughness, R t R yis the sum of these two, or the vertical distance from the deepest valley to the highest peak.: Again there may be more recent versions of the document.

Risk assessment and risk reduction BS Guidance and general information Withdrawn. As the stylus moves up and down along the surface, the transducer converts this movement into bs 1134 surface finish signal which is bs 1134 surface finish exported to a processor which converts this into a number and usually a visual profile. These Pages include various standards.

Indication of surface texture in technical product documentation Surface Finish Notes Surface Texture The accurate characterization of surface texture has become increasingly important in the instrument, computing, data storage, automotive and biomedical industries.

BS gives practical guidance on the measurement of bs 1134 surface finish texture using a stylus instrument. Find Similar Items This product falls into the following categories.
