Geometrical Product Specification (GPS) - Indication of surface texture in technical product documentation
This International Standard specifies the rules for the indication of surface texture in technical product documentation (e.g. drawings, specifications, contracts, reports) by means of graphical symbols and textual indications.It is applicable to the indication of requirements for surfaces by means of profile parameters, according to ISO 4287, related to the R-profile (roughness parameters), W-profile (waviness parameters) and P-profile (structural parameters), to motif parameters, according to ISO 12085, related to the roughness motif and waviness motif, as well as to parameters related to the material ratio curve according to ISO 13565-2 and ISO 13565-3.NOTE For the indication of requirements for surface imperfections (pores, scratches etc.), which cannot be specified using surface texture parameters, reference is made to ISO 8785, which covers surface imperfections.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.
The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
With Requirements, quickly access the main part of the normative text!
