DIN EN 187-1 1991-12 PDF

Full title and description

DIN EN 187-1:1991-12 — Ceramic tiles — Extruded ceramic tiles with a water absorption of 6 % < E ≤ 10 % (product group AIIb) — Part 1. The query prefix "STB" in your title appears to be an external/catalog identifier; the official designation is DIN EN 187-1:1991-12 (adoption of EN 187-1:1991).

Abstract

This standard specifies the sizes, dimensional tolerances, mechanical, physical and chemical requirements, surface quality requirements and marking for extruded ceramic tiles with water absorption between 6 % and 10 % (group AIIb). It references standardized test methods and makes note of slip-resistance and related test standards; Part 1 covers the majority of AIIb tiles while a Part 2 covers certain country-specific products.

Key bibliographic and lifecycle details above are based on the EN 187-1:1991 record and its DIN adoption and later withdrawal/supersession.

Scope

Applies to extruded (stranggepreßte) ceramic tiles in product group AIIb with water absorption 6 % < E ≤ 10 %, intended for internal and external use (mainly floors and also walls). The standard is limited to first-quality extruded tiles and excludes certain special national products (for example terre cuite, cotto or baldosin catalan), which are addressed by Part 2 or by other national standards. It defines dimensional, mechanical, physical and surface quality requirements plus marking and ordering information.

Key topics and requirements

• Product classification: identification of product group AIIb (water absorption 6 % < E ≤ 10 %).
• Dimensional requirements and tolerances (sizes, edge/corner tolerance, flatness).
• Mechanical and physical properties (strength, resistance to abrasion, water absorption tests and related acceptance criteria).
• Chemical resistance and surface quality requirements (appearance, defects, glaze/unglazed characteristics where applicable).
• Marking, designation and ordering information required on tiles and delivery documents.
• References to standardized test methods (slip resistance, abrasion, water absorption, thermal shock where relevant).

Typical use and users

Used historically by ceramic tile manufacturers (product specification and quality control), test and inspection laboratories, architects and specifiers preparing material specifications, procurement departments, and standards/ conformity bodies assessing tile conformity to European product requirements. Although this specific part has been withdrawn, its technical content was incorporated into later consolidated standards used by the same groups.

Related standards

Part 2 of EN 187 (EN 187-2:1991) covers certain country-specific AIIb tiles; EN 87 (definitions, classification and characteristics), and a range of EN/ISO tile test standards (for water absorption, abrasion, chemical resistance, thermal shock, scratch hardness etc.) are closely related. EN 187 (both parts) was later subsumed/replaced by broader consolidated standards in the EN/ISO tile suite (for example EN 14411 family in later revisions).

FAQ

Q: What is this standard?

A: EN 187-1:1991 (adopted as DIN EN 187-1:1991-12) is a European standard that specified requirements for extruded ceramic tiles with water absorption 6 % < E ≤ 10 % (product group AIIb), Part 1 covering the majority of such tiles.

Q: What does it cover?

A: It covers sizes, dimensional tolerances, mechanical, physical and chemical requirements, surface quality, marking and references to test methods for first-quality extruded ceramic tiles in the specified absorption range. Part 2 covered certain country-specific tile types.

Q: Who typically uses it?

A: Manufacturers, test laboratories, architects and specifiers, procurement and conformity assessment bodies involved with ceramic floor and wall tiles.

Q: Is it current or superseded?

A: This part is withdrawn/superseded in national adoptions; the EN 187 series has been consolidated into later tile product standards (for example the EN/ISO series and EN 14411 family used in subsequent national adoptions). Check the current national adoption (e.g., DIN EN 14411:2004 adoption) for the up-to-date normative references.

Q: Is it part of a series?

A: Yes — EN 187 was published in two parts (Part 1 and Part 2) addressing extruded AIIb tiles; it also forms part of a wider set of EN standards for ceramic tiles and tile testing (EN 87, EN 98–106, EN 122, EN 154, etc.).

Q: What are the key keywords?

A: Extruded ceramic tiles, AIIb, water absorption 6–10%, dimensional tolerances, surface quality, marking, tile test methods, EN 187, DIN EN 187-1.
