Description (English):

This part of ISO 5436 defines Type F1 and Type F2 software measurement standards (etalons) for verifying the software of measuring instruments. It also defines the file format of Type F1 software measurement standards for the calibration of instruments used for measuring the surface texture by the profile method defined in ISO 3274. NOTE 1 Throughout this part of ISO 5436, the term "softgauge" is used as a substitute for "software measurement standard Type F1". NOTE 2 Formerly, "measurement standards" were referred to as "calibration specimens". NOTE 3 ISO 3274 only refers to instruments with independent reference datums.

Abstract

Overview

ISO 5436-2:2012 - "Geometrical product specifications (GPS) - Surface texture: Profile method; Measurement standards - Part 2: Software measurement standards" specifies software-based measurement standards for verifying surface texture measurement software. The standard defines two types of software etalons: Type F1 (softgauge / reference data files) and Type F2 (reference software), the file format for Type F1 (.smd) and the required metadata for traceable calibration of profile-method surface texture instruments (as defined in ISO 3274).

Keywords: ISO 5436-2, surface texture, profile method, software measurement standards, softgauge, .smd, metrology, GPS.

Key Topics

Type F1 - Reference data (softgauge):
- Computer data files (.smd) that represent a digital primary profile for software verification.
- File uses 7-bit ASCII, divided into four records, terminated by ASCII 3 and ASCII 26.
- Header (Record 1) includes revision string, file identifier, feature type (PRF/SUR), axis info (CX/CY/CZ, PR/PA), number of points, units, scale factor and data type (I/L/F/D), and incremental spacing.
- Record 2 is optional metadata (DATE, INSTRUMENT_ID, PROBING_SYSTEM, COMMENT, etc.).
- Record 3 contains the raw data; Record 4 provides a checksum.
Type F2 - Reference software:
- Traceable software used to compute certified results from common input data; used to compare/calibrate instrument software.
- Type F2 can be used to certify Type F1 reference data.
Traceability and uncertainty: Reference software values and reference data must be traceable and suitable for producing known uncertainties in measurands.
Scope of verification: Designed to verify filter algorithms, parameter calculations, form removal, decimation, stylus corrections and other processing steps up to the primary profile.

Applications

Calibration and verification of surface texture measurement systems (stylus and other profile-type instruments).
Quality and metrology labs ensuring software implementations conform to GPS methods.
Instrument manufacturers and software developers validating filtering, parameter calculations, and file I/O.
Research and services that require certified reference data (.smd softgauges) for inter-laboratory comparisons or software certification.

Related Standards

ISO 3274 (profile instruments - nominal characteristics)
ISO 5436-1 (material measures for surface texture)
ISO 16610-21 (linear profile filters - Gaussian)
ISO 17450-2, ISO/IEC Guides on uncertainty and metrology vocabulary

Practical tip: use Type F1 .smd softgauges together with Type F2 reference software to separately validate data handling and algorithmic processing in your surface texture measurement workflow.
