Why Standards Matter When You Buy PVC Flooring
When you import PVC flooring from overseas, the test report is the only objective evidence of quality you can verify before payment. Marketing language varies by supplier, but a report from an accredited laboratory tells you exactly how the product performed on fire, abrasion, indentation and dimensional stability.
Different projects and markets require different standards. A hospital tender in the UK may ask for BS 476 Class 1; a retail chain in Dubai may specify EN 13501-1 Bfl-s1; an architect in the US often references ASTM E648. Knowing which report to request — and how to read it — prevents costly specification failures and protects your project timeline.
The Standard Families at a Glance
- European (EN / EN ISO): The most widely referenced system outside North America. Harmonised under CE marking for products sold in the EU.
- International (ISO): Overlaps heavily with EN — most European flooring standards are now joint EN ISO documents.
- American (ASTM): Used for US and many Latin American / Gulf projects.
- British (BS): Historic UK standards still specified for fire performance in UK-influenced markets, hospitals and schools.
- Voluntary certifications (FloorScore, CE): Indoor-air-quality and regulatory markers that open doors to green-building projects.

EN ISO 10582 — Heterogeneous PVC Floor Coverings (Specification)
The core product specification for heterogeneous (multi-layer) vinyl flooring: PVC backing, glass-fibre reinforcement where present, printed decor and transparent wear layer. It defines thickness tolerances, dimensional stability, indentation, colour fastness and other performance requirements. In the legacy European numbering, compact heterogeneous sheet fell under EN 649, which spanned both homogeneous and heterogeneous PVC sheet; the current reference for non-cushioned (compact) heterogeneous sheet is EN ISO 10582. Foam-backed heterogeneous sheet is specified separately under EN ISO 11638 (formerly EN 651).
Ask for it when: your project is in Europe, the Middle East or Africa and you are buying multi-layer vinyl sheet or tile.
EN ISO 10581 — Homogeneous PVC Floor Coverings (Specification)
The companion specification for homogeneous (through-colour) vinyl sheet — the same colour and composition through the entire thickness. Widely specified for hospitals and schools where wear must not reveal a different colour underneath. The legacy European reference EN 649, which spanned both homogeneous and heterogeneous PVC sheet, was withdrawn in 2014; its homogeneous scope is now covered by EN ISO 10581 and its heterogeneous scope by EN ISO 10582.
Ask for it when: you buy through-colour sheet for healthcare or education projects. Our homogeneous vinyl sheet is documented to this family of requirements.
EN 660-2 — Abrasion Resistance (Frick-Taber Test)
Measures how much material is lost when a rotating abrasive wheel wears the surface. Results are grouped:
- Group T: lowest weight loss — heavy commercial and industrial traffic
- Group P: general commercial traffic
- Group M: lighter residential or occasional commercial use
- Group F: lightest tier — low-traffic rooms and cushioned products
Ask for it when: the floor will carry constant foot traffic — hotels, corridors, retail, hospitals. Always check the group, not just the report's existence. See how to select an EN 660-2 wear class for the F/M/P/T scale and how to read the report.
EN ISO 10874 (formerly EN 685) — Classification of Areas of Use
Translates expected traffic into a classification number. For commercial vinyl sheet the relevant classes are 31/32/33 (light / general / heavy commercial) and 41/42/43 (light / general / heavy industrial). A product rated 33 can be used anywhere 31 or 32 is specified; rating 42 covers most light industrial uses.
Ask for it when: your specifier or tender document cites a usage class such as "class 33" or "class 42".
EN 13501-1 — European Fire Classification (Bfl-s1)
Classifies reaction to fire. For floor coverings the code reads Bfl-s1: "Bfl" is the fire class for floors (B = very good reaction to fire), "s1" the lowest smoke production. It is the classification required for CE-marked floor coverings in the EU.
Ask for it when: any EU project, or Gulf / African projects that follow EU practice.
BS 476 Part 7 — UK Surface Spread of Flame (Class 1)
The historic UK standard measuring how quickly flame spreads across a surface. Class 1 is a high surface spread of flame rating and the traditional requirement for hospitals, schools and public buildings in UK-influenced markets (Middle East, Hong Kong, Singapore, Nigeria and others). Within the British system, Class 0 — combining BS 476 Parts 6 & 7 — denotes a higher overall grade.
Ask for it when: the tender references UK practice or a British-standard healthcare project.
ASTM E648 — Critical Radiant Flux (Class I / Class II)
The US method for measuring how a floor covering resists flame spread under a radiant heat panel. Class I (critical radiant flux ≥ 0.45 W/cm²) is the higher rating; Class II (≥ 0.22 W/cm²) is the second tier. US commercial and healthcare projects routinely require Class I.
Ask for it when: your project is in the US, or follows US code practice internationally.
ASTM F1700 — Homogeneous Vinyl Sheet Specification (US)
The US product specification for homogeneous vinyl sheet, covering composition, thickness, and performance testing aligned to American practice. Useful when US architects or GCs ask for an ASTM-based sheet specification.
EN ISO 24343-1 — Residual Indentation
Measures how deeply a static load (e.g. a cabinet or trolley wheel) permanently dents the floor after the load is removed. Low residual indentation means furniture and equipment leave no lasting marks.
Ask for it when: the floor will carry static loads — hospitals, offices, warehouses.
EN ISO 23999 — Dimensional Stability and Curling
Exposes a sample to heat and measures expansion/contraction and edge curling. Low values mean the floor will not shrink or curl after installation, protecting welded seams and joints.
FloorScore® — Low-VOC Indoor Air Quality Certification
An independent certification (SCS Global Services) that screens the product for a defined list of volatile organic compounds — TVOC, formaldehyde, acetaldehyde and others — against strict emissions limits under the CDPH Standard Method (CA 01350). Hospitals and green-building projects (LEED, BREEAM, Estidama) routinely require it to protect indoor air quality.
Ask for it when: healthcare, education, or any project pursuing green-building credits.
CE Marking (EN 14041)
Legal requirement for floor coverings sold in the European Economic Area. The harmonised standard EN 14041 covers essential characteristics — fire behaviour, slip resistance, thermal resistance and formaldehyde emissions. CE is a market-access requirement, not a quality badge. In 2026 the regulation behind it was replaced — see what changed under the EU Construction Products Regulation.

What We Publish, and What Backs It
Every figure on this site falls into one of three levels: measured in a test report, declared in a technical data sheet, or agreed in a contract. The table below says which level each published claim sits on, so a specifier can ask for the right document instead of the whole folder.
| Published claim | Level | Document we can send |
| Fire reaction — BS 476 Part 7 Class 1 (homogeneous) | Test report | homogeneous-fire-test-report.pdf |
| Fire reaction — BS 476 Part 7 Class 1 (heterogeneous) | Test report | heterogeneous-fire-test-report.pdf |
| Mould resistance | Test report | homogeneous- / heterogeneous-mould-test-report.pdf |
| VOC and indoor air | Test report | …-physical-chemical-voc-rohs-test-report.pdf |
| RoHS (heterogeneous) | SGS report | heterogeneous-sgs-rohs-test-report.pdf |
| Thickness, roll size, coverage | Declared in TDS | TDS on request / product page |
| Warranty term | Contract | quotation and sales contract |
If a claim is not in this table, we do not publish a figure for it. Only the test-report row is a measured value; the other two are declared specifications and commercial terms, and they are labelled as such on purpose.
How to Read a Test Report in 5 Steps
- Check the laboratory and standard edition. Reports must come from an accredited lab (e.g. SGS, TÜV, Intertek, Bureau Veritas) and cite the current edition of the standard — not a 10-year-old reference number.
- Find the fire classification. Confirm the exact class/group your tender demands: Bfl-s1, Class 1 (BS 476), or Class I (ASTM E648). "Passed" without a class is not a pass.
- Locate the abrasion group. For EN 660-2, the result is a letter (T/P/M/F). For a commercial corridor you want Group T. Note whether the report covers the product and colour you are actually buying.
- Verify indentation and dimensional stability numbers. These protect you from floors that dent under furniture or shrink and open seams after installation.
- Confirm the product identity. The report must name the exact product code and thickness you are buying. A report for a different series or wear layer does not certify your goods.
Frequently Asked Questions
Which test report should I request from a vinyl flooring supplier?
Ask for the report that matches your project market. European and Middle East projects typically require EN ISO 10582 or EN ISO 10581 specification (legacy EN 649/EN 651 numbers may appear on older reports), EN 13501-1 fire classification Bfl-s1 and EN 660-2 abrasion group. US projects require ASTM E648 (Class I) and ASTM F1700 for homogeneous sheet. Healthcare projects additionally ask for FloorScore or an equivalent low-VOC certification. Download our published test reports for homogeneous and heterogeneous vinyl.
What does BS 476 Class 1 mean for vinyl flooring?
BS 476 Part 7 Class 1 is a high surface spread of flame rating in the UK standard, widely specified for hospitals, schools and public buildings in UK-influenced markets. It measures how far and how fast flame spreads across a surface under controlled test conditions. Within the British system, Class 0 (BS 476 Parts 6 & 7 combined) denotes a higher overall grade.
What replaced the old EN 649 and EN 651 standards?
Legacy European numbering changed when CEN adopted the EN ISO system: EN 649 (withdrawn 2014) covered both homogeneous and heterogeneous PVC sheet — homogeneous sheet is now specified to EN ISO 10581 and heterogeneous (compact) sheet to EN ISO 10582. EN 651, the separate specification for foam-backed PVC sheet, is now EN ISO 11638. If a datasheet cites only a legacy number such as EN 649 or EN 651, ask the supplier for the current EN ISO edition.
What is EN 660-2 Group T in abrasion testing?
EN 660-2 measures abrasion resistance using the Frick-Taber method and groups products by weight loss. Group T is the highest category, suited to heavy commercial and industrial traffic; Groups P and M suit general commercial and lighter use, and the lightest tier, Group F, applies to low-traffic and cushioned products.
Why do hospitals ask for FloorScore certification?
FloorScore is an independent low-VOC certification from SCS Global Services. Hospitals and green-building projects (LEED, BREEAM) specify it to guarantee indoor air quality — the flooring is tested for volatile organic compounds and must meet strict emissions limits before the certificate is issued.
