BS EN ISO 13565-1-1998 (1999) PDF

Full title and description

STB BS EN ISO 13565-1:1998 (published/adopted 1999 in some national catalogues) — Geometrical product specifications (GPS) — Surface texture: Profile method; surfaces having stratified functional properties — Part 1: Filtering and general measurement conditions. This part defines a filtering procedure and general measurement conditions intended for plateau-like (stratified) surfaces to suppress valley influence on the reference line used for profile-based surface texture assessment.

Abstract

This standard describes a special profile filtering method for surfaces that have stratified functional properties (for example a relatively smooth plateau with deeper valleys). The filter reduces the influence of valleys on the reference line so a more representative baseline is produced for subsequent roughness evaluation. The document is the first part of the ISO 13565 profile-method series and is accompanied by a technical corrigendum issued in 1998.

Scope

Specifies a filtering method and general measurement conditions for use with surfaces that have stratified functional properties — i.e., a plateau-like upper layer with deeper valleys — where standard Gaussian filtering (ISO 11562/ISO 4287 approaches) can allow valley features to bias the reference (mean) line. The filter described reduces valley influence, producing a reference line better suited for calculating profile parameters on such surfaces. The part covers measurement setup, filtering intent and constraints rather than exhaustive parameter lists (these are covered in related parts).

Key topics and requirements

• Definition and rationale for a valley-suppressing filter to generate an improved reference line for plateau-type surfaces.
• General measurement conditions and recommendations for applying the filter in profile measurements.
• Normative relation to profile measurement practice (stylus/profile instruments) and to the other parts of ISO 13565 (which address parameter evaluation).
• Technical corrigendum (1998) correcting or clarifying small editorial/technical points in the original 1996 text.
• Note on standard evolution: parameter definitions and some profile procedures from ISO 13565 parts 2 and 3 and related profile standards were later consolidated and replaced by the ISO 21920 profile series (users should consult ISO 21920 for current parameter definitions).

Typical use and users

Used by metrology and quality‑control engineers, surface metrology laboratories, manufacturing engineers and R&D groups concerned with functional surface finishes (for example plateau-honed cylinder bores, honed and honed/peened surfaces, certain coated or ground surfaces). Typical applications include characterizing plateau/valley surfaces where valley-dominated profiles would otherwise distort roughness parameters and functional assessments. National adoption copies are used by procurement and standards librarians for specification and compliance.

Related standards

Part of the ISO 13565 series (Parts 1–3). Related and successor documents include ISO 13565-2 and ISO 13565-3 (height-characterization methods) — both subsequently superseded in scope by the ISO 21920 series (notably ISO 21920-2:2021 for parameter definitions and ISO 21920-3:2021 for specification operators). Other historical related profile standards include ISO 4287 and ISO 4288 (rules/terms), many of which were updated or replaced when ISO 21920 was published. Users should check ISO 21920 series for the currently recommended parameter and operator definitions.

FAQ

Q: What is this standard?

A: ISO 13565-1 (published as ISO 13565-1:1996 with a technical corrigendum in 1998 and adopted as BS EN ISO 13565-1:1998) is the part of the ISO 13565 profile-method family that specifies a filtering method and general measurement conditions for surfaces with stratified functional properties (plateau + valleys).

Q: What does it cover?

A: It covers a special filtering approach and the accompanying general measurement guidance needed to reduce valley influence on the profile reference line prior to calculation of profile parameters; it does not itself define the full set of height/parameter calculations (those are in other parts of the series).

Q: Who typically uses it?

A: Metrology labs, surface and quality engineers, manufacturers (cylinder bores, honed/ground surfaces), instrument and software vendors implementing profile-filter algorithms, and standards committees or procurement specialists using national adoptions.

Q: Is it current or superseded?

A: ISO 13565-1:1996 (with Corrigendum 1998) remains the published Part 1 document for the valley-suppressing filter according to ISO records; however, parts of the older profile standard family (notably ISO 13565-2 and ISO 13565-3 and other profile parameter standards) have been superseded or consolidated into the ISO 21920 series (ISO 21920-2:2021 and related documents). Users should consult the ISO catalogue and the ISO 21920 series for the most up‑to‑date parameter definitions and profile-specification operators.

Q: Is it part of a series?

A: Yes — it is Part 1 of the ISO 13565 series (Parts 1–3). Parts 2 and 3 address height characterization methods; those parts have been superseded in part by the newer ISO 21920 profile standards for parameter definitions and operators.

Q: What are the key keywords?

A: Surface texture, profile method, stratified functional properties, plateau, valleys, filtering, reference line, roughness parameters, ISO 13565, BS EN adoption, STB edition.
