Full title and description

STB DIN EN ISO 13565-1: Geometrical product specifications (GPS) — Surface texture: Profile method — Surfaces having stratified functional properties — Part 1: Filtering and general measurement conditions. This is the German (DIN/EN) adoption (April 1998) of ISO 13565-1:1996, providing a specific filtering approach for surfaces with plateau-like regions and deep valleys to produce a more representative reference line for profile measurement.

Abstract

Describes a filtering method and general measurement conditions for profile-based surface texture assessment of stratified functional surfaces (plateau with deep valleys). The filter suppresses valley influence on the reference line so that the measured profile better represents the functional plateau. (ISO 13565-1:1996; adopted as DIN EN ISO 13565-1:1998-04).

Scope

This part specifies a filtering method and general measurement conditions for profile surface texture measurement of surfaces that have stratified functional properties — i.e., a finely finished plateau with relatively deep valleys and only a small amount of waviness. The method reduces the influence of deep valleys on the reference line derived by conventional filtering (ISO 11562) so the resulting reference line and derived profile parameters better characterise the functional plateau. Normative references include ISO 11562, ISO 3274 and ISO 4287.

Key topics and requirements

• Definition and application of a valley-insensitive filtering procedure for profile data to suppress valley influence on the reference line.
• General measurement conditions and recommendations for instruments and filtering when assessing stratified surfaces.
• Normative references and metrological context—links to ISO 11562 (phase-correct filters), ISO 3274 (nominal characteristics of contact instruments) and ISO 4287 (terms and parameters).
• Intended to improve repeatability and functional relevance of profile-based roughness assessments on plateau/valley type surfaces.

Typical use and users

Used by metrology laboratories, quality and process engineers, tribology and surface-engineering teams, and manufacturers in sectors where plateau/valley surface textures matter (e.g., automotive components, bearings, seals, sliding surfaces). Typical tasks include specification of measurement procedure, filter selection, and interpretation of profile-based surface parameters for functional performance.

Related standards

Closely related and often cited standards: ISO 11562 (filters — phase-correct filters); ISO 3274 (contact instrument characteristics); ISO 4287 (terms, definitions and parameters); ISO 13565 series (Parts 1–3: filtering and height characterizations). Note: Parts 2 and 3 of ISO 13565 (height-characterization methods) were later superseded/revised by newer ISO work (see ISO 21920 series updates). Also issued as EN ISO 13565-1:1997 and adopted nationally (e.g., DIN EN ISO 13565-1:1998-04).

FAQ

Q: What is this standard?

A: DIN EN ISO 13565-1:1998-04 is the German national adoption of ISO 13565-1:1996 (EN ISO 13565-1:1997). It specifies a filtering method and general measurement conditions for profile-based surface texture assessment of stratified (plateau/valley) surfaces.

Q: What does it cover?

A: It covers a filtering approach that suppresses the influence of deep valleys on the computed reference line so the measured profile better represents the functional plateau; it also sets out general measurement conditions and references to relevant instrument and parameter standards.

Q: Who typically uses it?

A: Metrology and QA/QC engineers, surface-analysis labs, designers and manufacturers in industries where surface functional behaviour (wear, lubrication, sealing) depends on plateau-type textures—e.g., automotive, bearing, hydraulic and tribological applications.

Q: Is it current or superseded?

A: The ISO 13565-1:1996 text was adopted nationally (DIN EN ISO 13565-1:1998-04). At ISO level the 1996 edition has received corrigenda (1998) and has been subject to periodic review; parts of the ISO 13565 series (Parts 2 and 3) have since been withdrawn and superseded by later standards (for example ISO 21920-series updates). For the precise current status in your national catalogue check the issuing body (DIN/ISO) — the published DIN text (1998-04) remains the national adoption of the ISO text.

Q: Is it part of a series?

A: Yes — ISO 13565 is a multipart series: Part 1 (filtering and measurement conditions), Part 2 (height characterisation using the linear material ratio curve) and Part 3 (height characterisation using the material probability curve). Note that Parts 2 and 3 were later revised/withdrawn and their contents consolidated or superseded by newer ISO work (see ISO 21920 updates).

Q: What are the key keywords?

A: Surface texture, profile method, filtering, stratified surfaces, plateau, valley, reference line, GPS, metrology.
