Resilient floor coverings - Determination of conventional pattern depth
This European Standard specifies three methods for determining conventional pattern depth by change in appearance of the characteristics of the pattern of resilient floor coverings which are classified as follows: Group 1: Patterns where the different bands (in colour and/or relief) are distributed in a uniform manner, wher the ration of pattern to background in small areas of 0,01 m2 to 0,02 m2 in not more than 1:4; Group 2: Patterns where this ration varies considerably where some areas of 0,01 m2 to 0,02 m2 may contain only one part of the pattern.
Elastische Bodenbeläge - Bestimmung der Dekortiefe
Diese Europäische Norm legt drei Verfahren zur Bestimmung der der Dekortiefe durch Aussehensveränderung der Dekors von elastischen Bodenbelägen fest, die wie folgt unterschieden werden: Gruppe 1: Dekors, bei denen die verschiedenen Aussehensbereiche (Farbe und/oder Relief) sich in einer gleichmässigen Folge wiederholen, wobei bei kleinen Bereichen von 0,01 m2 bis 0,02 m2 das Verhältnis zwischen Dekor und Hintergrund nicht grösser als 1/4 ist; Gruppe 2: Dekors, bei denen dieses Verhältnis beträchtlich schwankt, wobei einige Bereiche von 0,01 m2 bis 0,02 m2 möglicherweise nur einen Teil der Dekors enthalten.
Revêtements de sol résilients - Détermination de la profondeur conventionnelle du décor
La présente Norme Européenne prescrit trois méthodes de détermination de la profondeur conventionnelle du décor par le changement d'aspect des caractéristiques du décor des revêtements de sol résilients. Les différents décors sont classés de la manière suivante: Groupe 1: Décors où les plages d'aspect différent (couleur et/ou relief) sont réparties de façon uniforme et où le rapport "décor/fond" en petites surfaces comprises entre 1 dm2 et 2 dm2 n'est pas supérieur à 1/4; Groupe 2: Décors pour lesquels ce rapport varie de manière considérable.

Overview
EN 663:1994 is a CEN (European) standard that defines how to measure the conventional pattern depth of resilient floor coverings. The standard specifies three methods for determining pattern depth based on changes in the appearance of the flooring pattern. It is used to classify and quantify the visual relief and colour-pattern depth of non-textile resilient floor coverings for quality control, specification and comparative testing.
Key topics and technical requirements
- Scope: Measurement of conventional pattern depth for resilient (non-textile) floor coverings.
- Three measurement methods: The standard prescribes three distinct methods to assess pattern depth by observing change in appearance. (EN 663:1994 gives procedural detail in the full text.)
- Pattern classification: Flooring patterns are classified into two groups:
- Group 1: Patterns with uniformly distributed bands (colour and/or relief). The pattern-to-background ratio in small areas of 0.01 m² to 0.02 m² is not more than 1:4.
- Group 2: Patterns with highly variable distribution; some small areas (0.01 m² to 0.02 m²) may contain only a single part of the pattern.
- Applicable materials: Non‑textile resilient floor coverings (ICS 97.150).
- Standard identification: CEN European Standard EN 663:1994 (adopted nationally in some countries, e.g., SIST EN 663:1999 in Slovenia).
Practical applications
Who uses EN 663:1994 and why:
- Manufacturers - for product development, in-house QC and to ensure consistent pattern reproduction across production batches.
- Independent test laboratories - to perform standardized, repeatable measurements of pattern depth for certification and compliance testing.
- Specifiers, architects and interior designers - to compare visual texture and relief between products when selecting coverings for aesthetic or performance reasons.
- Contractors and procurement teams - to verify supplied materials match contract or tender specifications.
- Regulatory bodies and conformity assessment organizations - for harmonized assessment when pattern appearance is part of performance criteria.
Related standards
- Other CEN standards on resilient floor coverings cover properties such as wear resistance, slip resistance and dimensional tolerances. When specifying or testing flooring, combine EN 663:1994 with relevant performance standards to get a complete assessment.
