Why I Read the Flooring Technical Data Sheet Before the Price
Before I look at a quote, I open the flooring technical data sheet. Price tells me what a supplier wants to charge. The data sheet tells me what the supplier is willing to put in writing about the product, and the distance between those two is where most specification problems begin. Two floors can look identical in a sample and behave very differently once they are installed in a hotel corridor or over underfloor heating. The data sheet is the first place that difference shows up, if you know how to read it.
Most buyers skim a data sheet for three things: thickness, price per square meter, and a certificate logo. That is understandable. Data sheets are dense, full of standard numbers, and written by the party that is selling. But a data sheet is also the cheapest document to challenge. It costs nothing to ask what test method sits behind a number, and the answer tells you more about a supplier than any brochure. A sheet that says “meets international standards” is the flooring equivalent of “trust me”.
This guide walks through a typical sheet field by field: dimensions, wear ratings, fire class, slip resistance, emissions, moisture and heating. For each field I explain what the number means, what it does not mean, and what I would ask next. I use SPC, laminate and ResinCore as examples because those are the products I sell, but the reading logic works for any rigid or laminate floor. I am not a test laboratory, so where a standard sets exact limits I name the standard and link the source rather than quote figures I cannot back up.
Flooring Technical Data Sheet, Declaration of Performance, and Test Report: What Each Proves
Suppliers send several documents and call all of them “technical documents”. They are not interchangeable, and knowing which one proves what keeps a brochure claim from passing as a test result.
Data Sheet Versus Declaration of Performance
A data sheet is the supplier’s own summary of a product’s properties and carries no legal weight by itself. A Declaration of Performance, or DoP, is different. Under the Construction Products Regulation (EU) No 305/2011, the manufacturer who draws up the DoP takes responsibility for the product conforming to it, and the CE marking is affixed on that basis. For floor coverings the harmonised standard behind it is EN 14041, which lists the characteristics a DoP covers: reaction to fire, pentachlorophenol content, formaldehyde emission, slip resistance, electrical behaviour, thermal conductivity and water-tightness.
For each characteristic, the manufacturer either declares a performance or writes NPD, which stands for No Performance Determined. In the DoPs I read, reaction to fire always carries a class, while thermal conductivity and water-tightness are often NPD. That is useful. If a data sheet states a slip value, the supplier has made a claim, so a report should exist. If it states none, that is not automatically a warning sign.
Data Sheet Versus Test Report
A test report records one test, on one sample, using one method, on one date. It is the document that carries weight, but it proves only what it covers. Check that it names the same product, thickness and decor as the data sheet, and that the date is recent enough to matter.
Then check the laboratory. ISO/IEC 17025 accreditation covers a defined scope, so a lab can be accredited and still not cover the method on your report. ILAC advises that the best way to check a certificate or report is to contact the accreditation body, which can confirm the laboratory’s status and its scope. Accredited labs also state the standards and methods used in their reports, so compare that list with the scope before you trust the result.
| Document | What it is | What it proves | What it does not prove |
|---|---|---|---|
| Brochure | Marketing summary | Intended positioning | Anything that was tested |
| Technical data sheet | Supplier’s property summary | What the supplier claims | That the claim was tested |
| Declaration of Performance | Legal declaration for CE-marked products | Declared performance of essential characteristics | Properties the manufacturer chose not to claim |
| Test report | Laboratory record of one test | One result on one sample | Other thicknesses, decors or batches |
| Certificate (for example FloorScore) | Third-party programme result | Compliance with that programme’s criteria | Anything outside its scope |

Reading the Dimension and Thickness Block
The first block of most data sheets looks harmless, which is exactly why mistakes hide there. Nothing in it is difficult, but every line has a trap.
Total Thickness, Core, and Wear Layer
Thickness usually appears in three forms: total thickness, core thickness and wear layer thickness. Total thickness can include an attached underlay, so a 6 mm floor may really be a 5 mm floor with a 1 mm pad. Ask which it is. For SPC I read the wear layer separately, because the wear layer, not the total, decides how long the surface lasts.
For laminate and other wood-based products, the sheet should also name the core and its density. Our MoistureShield 1000 uses an HDF core of 1000 kg/m³, against roughly 600 to 800 kg/m³ for ordinary laminate. That is exactly the kind of number that belongs on a data sheet, because it changes how the floor behaves around moisture.
Plank Size, Tolerances, and Locking System
Plank length and width should carry a tolerance, not just a nominal size. A plank that drifts by a millimetre or more from its stated size can open gaps in the locking system, especially on long runs, so I ask for the tolerance before I ask for the price.
The sheet should also name the locking system. Our EIR parquet collection, for example, uses a licensed Välinge 5G click system. A named, licensed profile gives you a company to ask about joint strength. A generic “click system” gives you no one to ask. Bevel type matters too, since it affects how joints look and how dirt collects along them.
Reading Wear Ratings on a Flooring Technical Data Sheet
Wear fields are where marketing and measurement are most likely to drift apart, so I read them in pairs: a thickness and a rating, or two ratings that should agree.
Wear Layer Thickness for SPC
My working rule is simple. I treat 0.3 mm as the floor for residential use, and 0.5 mm as the starting point for commercial spaces and for homes with large or active pets. Ask whether the figure is nominal or measured. A nominal 0.5 mm that measures noticeably less is a conversation worth having before the order, not after the first scuff marks.
Thickness is also not the whole story. Surface treatment and the formulation of the film matter, which is why thickness should always be read together with a rating. My guide to wear-resistant flooring goes deeper on how to match the two to a space.
AC Ratings and Use Classes
Laminate uses AC ratings, which run from AC1 to AC5 under EN 13329. The North American Laminate Flooring Association stresses that an AC rating measures abrasion resistance alone, not impact or stain resistance, so it never tells the whole story.
Resilient floors, including SPC, usually quote an EN ISO 10874 use class instead. Class 23 means heavy domestic use, 33 means heavy commercial use, and 42 or 43 mean light industrial use. Compare the two fields on the same sheet. In my experience, a 0.3 mm wear layer sitting next to a heavy commercial class is a mismatch worth questioning.
Reading the Fire Classification Line
Fire class is the one performance line that must appear, so it is worth reading carefully. Floor coverings use their own scale under EN 13501-1: A1fl, A2fl, Bfl, Cfl, Dfl, Efl and Ffl. The “fl” suffix matters. It tells you the result came from the flooring test, EN ISO 9239-1, rather than from the test used for wall and ceiling products. Measurlabs sets out the criteria for each class, and the main numbers are below.
| Class | Minimum critical flux (EN ISO 9239-1) | Also required |
|---|---|---|
| Bfl | 8.0 kW/m² | Small-flame ignitability test |
| Cfl | 4.5 kW/m² | Small-flame ignitability test |
| Dfl | 3.0 kW/m² | Small-flame ignitability test |
Smoke is classified separately. In the same flooring test, s1 means smoke of 750 percent-minutes or less, and s2 means the floor exceeded that.
Three habits help. First, insist on the smoke subclass, so “Bfl-s1” rather than just “Bfl”. Second, be wary of a flooring product quoted as “B-s1” or “A2-s1” with no “fl”, because it may be shorthand or it may borrow a result from a different test. Ask for the classification report. Third, ask whether the classification covers your exact product or a family of similar products, and which product in that family was actually tested. National building rules decide which class a project needs, so confirm that with the local authority rather than the supplier.
Slip Resistance Claims on a Flooring Technical Data Sheet
Slip claims are the easiest numbers to misread, because several tests with very different conditions all produce a number or a letter that looks like a rating. The table shows the three I see most often.
| Method | Conditions | Limit to remember |
|---|---|---|
| DIN 51130 (R9 to R13) | Person walks on an oiled ramp in safety footwear | Footwear and oil are specific to the method |
| EN 13893 (dynamic coefficient of friction) | Laboratory test on a dry, ex-factory surface | Not suitable for wet or contaminated surfaces |
| Pendulum test | Rubber slider on a swinging arm, wet or dry | Depends on slider type and surface condition |
The German Social Accident Insurance describes the DIN 51130 ramp test: a person walks on an oiled ramp, and the angle at which they begin to slip sets one of five classes. The scope of EN 13893 states that it applies to dry, ex-factory surfaces and is not suitable for wet or contaminated ones, so a value from that method says nothing about a wet entrance or a kitchen.
I ask three questions: which method, which surface condition, and which footwear. I never compare an R class on one sheet with a friction coefficient on another. If the room will get wet, I ask for a wet method. A missing slip value is a prompt to ask, not proof of a problem.
Reading Emissions and Indoor Air Fields
Emission fields show up as a formaldehyde class, a VOC value or a certification logo. They answer different questions, so I read them separately.
Formaldehyde matters where there are wood-based layers, such as the HDF core in laminate or the board layers in engineered wood. In CE documentation it is usually reported as a class such as E1 under EN 717-1. SPC has no wood-based core, so the formaldehyde field may read “not applicable”. When it does, ask for VOC data instead of letting the field quietly disappear. My guide to formaldehyde-free flooring explains why these emission classes matter for indoor air.
Two more habits apply here. A class tells you which band a floor falls into, not the measured value, so ask for the value when it matters. And claims such as “phthalate-free” or “low VOC” should name the substances or the limits they refer to, together with the report that supports them. Without that, the phrase is a slogan.
Certification logos need the same scrutiny. FloorScore is a programme run by SCS Global Services for emissions from hard surface flooring, and it is recognised by LEED v4.1, WELL and BREEAM. Our SPC range carries it, and I would still encourage you to check the certificate against the issuer’s listing rather than rely on my word. A logo is not data. A certificate number you can verify is.
Reading Moisture, Stability, and Heating Fields
Look at the core, not the adjective. SPC and ResinCore cores do not swell when water reaches them, while a laminate core is water resistant but not waterproof, and density is what separates a good laminate from a poor one in humid rooms. My waterproof flooring guide explains the difference. Also ask whether “waterproof” describes the plank or the installed floor, because joints and edges can still let liquid through to the subfloor. Water-tightness is a separate line on a Declaration of Performance and is often marked NPD, so a sheet that says “waterproof” should come with a report and a method.
For stability, ask for the dimensional change after heat exposure and the method behind it. Resilient floors are usually tested under EN 434. A figure with no temperature, duration or method is decoration. This field matters most for floors beside large glazed facades, in conservatories and over heating.
For underfloor heating, the number you need is thermal resistance, measured under EN 12667. Because thermal conductivity is often marked NPD on a Declaration of Performance, an empty field means you should ask. Then ask your heating contractor what maximum resistance their system tolerates.
Red Flags on a Flooring Technical Data Sheet
Most weak data sheets are not dishonest, they are lazy templates. But the patterns repeat, and once you know them you can screen a sheet in two minutes. This table lists what I look for and what I ask.
| Red flag | Why it matters | What I ask |
|---|---|---|
| “Meets international standards” with no standard number | Nothing to verify | Which standard, which edition, which report? |
| Fire class without “fl” or without a smoke subclass | May borrow a result from another test | Please send the classification report |
| Ranges instead of values, such as “0.3 to 0.5 mm” | You cannot tell what you will receive | Which SKU, and what is the measured value? |
| No test date, laboratory or report number | A claim without evidence | Which lab, when, and is it accredited for this method? |
| One sheet covering several thicknesses or decors | The tested sample may not match yours | Which product was actually tested? |
| Slip value with no method or condition | Dry and wet results are not interchangeable | Which method, and was it wet or dry? |
A supplier who fixes these quickly when asked is usually a good sign. A supplier who cannot is showing you what the rest of the file looks like.
Frequently Asked Questions
What should a flooring technical data sheet always include?
At a minimum: product name and SKU range, total thickness and wear layer, dimensions with tolerances, core type, locking system, fire class with its smoke subclass, the standard and test method behind each performance value, and a date or issue number. Claims about slip, emissions and heating suitability should name their methods too.
Is a data sheet enough to specify a floor?
No, it is where you start. For anything with consequences, such as fire class, slip in wet areas or underfloor heating, ask for the test reports and, for CE-marked floors, the Declaration of Performance. Then check that the sample in your hand matches the product on the sheet.
What is the difference between a data sheet and a Declaration of Performance?
A data sheet is the supplier’s own summary and has no legal standing by itself. A Declaration of Performance is a legal declaration under the Construction Products Regulation, tied to a harmonised standard and the CE mark.
How often should a data sheet be updated?
Whenever the product, the supplier or the test changes, and it should carry a date or issue number so you can tell. If a sheet is undated, or older than the tests it cites, ask whether the figures still apply.
Can I compare two suppliers’ data sheets directly?
Only when the same methods sit behind the numbers. Two slip values, or two thicknesses measured differently, are not comparable. Line the sheets up field by field, note the method for each, and mark any field where the methods differ.
Conclusion: Treat the Flooring Technical Data Sheet as the Start, Not the Finish
A data sheet is a claim in a tidy format. It becomes evidence only when a method, a date and a laboratory stand behind each number. If you remember four habits, make them these: know which document proves what, read fields in pairs so mismatches show, insist on the method behind every performance value, and treat red flags as questions rather than accusations.
When I have only five minutes with a new sheet, I do it in this order: fire class and its subclass, wear layer next to the use class, the slip method, the emission evidence, and finally the dates. If any of those five lines is vague, I stop and ask before I read anything else, because a sheet that is vague in the places that carry risk is rarely precise elsewhere.
