How to Read a Porcelain Tile Technical Data Sheet
A buyer-friendly guide to tile size, thickness, water absorption, breaking strength, DCOF, chemical resistance, shade/calibre, application and packing information.

A technical sheet is useful only when each value is read in context
Tile technical data combines dimensions, body characteristics, surface performance and application information. One impressive number should not be used to ignore the rest of the system.
For B2B purchasing, the goal is to confirm that the exact product and batch documentation meet the project requirement—not to collect the largest possible list of marketing claims.
Common technical-sheet fields
| Field | What it describes | Buying question |
|---|---|---|
| Nominal size | Product format | What are the actual work size/tolerances? |
| Thickness | Nominal tile thickness | How does total floor build-up work? |
| Water absorption | Body porosity classification | Does the declared value meet the required classification? |
| Breaking strength / flexural data | Mechanical test response | Which method and product geometry apply? |
| DCOF/use classification | Surface friction under defined method | Is it relevant to the intended condition? |
| Chemical/stain resistance | Response to defined agents/tests | Does the exact surface have the required rating? |
Start with identity and applicability
Confirm design number, series, size, finish and revision date before reading performance values. A report for a different surface or older production should not automatically be applied to the tile being ordered.
For project submittals, keep the approved document with the product reference so later substitutions are visible.
Understand what each test does not prove
Water absorption does not prove slip performance. Breaking strength does not predict every impact. DCOF does not guarantee no one will slip. Chemical resistance does not mean every cleaner is safe for grout and adjacent materials.
Technical literacy is largely the ability to keep these different questions separate.
Look for the test method and classification
A number without a method is difficult to compare. Porcelain definitions commonly reference water absorption measured under a recognized standard, while DCOF values rely on a specified test method.
If two suppliers provide values under different standards, ask whether they are truly comparable before ranking them.
Connect product data to packing and installation
For an actual order, technical approval is followed by practical data: pieces per box, square metres per box, box weight, pallet configuration, shade/calibre and installation requirements.
TAG Ceramic publishes 600×600 mm as its core format and 8.5 mm as a nominal core-product thickness reference; final orders should still be confirmed against the current product and packing data.
What is the most important number on a tile data sheet?
There is no single universal number. The important fields depend on the project condition and applicable standard.
Can two test values from different standards be compared directly?
Not always. Confirm the test method, specimen and classification before comparing.
Does a porcelain label replace the technical sheet?
No. Porcelain classification is only one characteristic; application, surface, mechanical and installation information still matter.
Should old technical sheets be reused for repeat orders?
Use the current document for the exact product because specifications, testing and production references can change.
Continue with product-specific information
Use TAG Ceramic product pages, technical resources and current packing information to confirm the exact design before ordering or project approval.
Open TAG Technical ResourcesRead every value together with its test method and product identity
A technical sheet is meaningful only when it clearly applies to the design, size, finish and revision being supplied. A number without a test method or classification can be difficult to compare with another supplier’s value.
Start by confirming product identity and date, then read body, surface and application characteristics as separate questions.
Need help interpreting DCOF?
Use the dedicated ANSI A326.3 explainer before treating a friction value as a slip-safety guarantee.
DCOF guideKeep body, surface and installation data separate
Water absorption describes body porosity; it does not prove a specific wet-surface classification. Breaking strength or flexural data do not represent every impact or rolling load. Chemical resistance of the tile face does not automatically apply to grout, sealant or trims.
A reliable specification connects each value to the question it actually answers.
Commercial ordering adds packing and traceability fields
After technical approval, confirm pieces per box, square metres per box, gross weight, pallet configuration, shade/calibre references and current marking. These fields affect freight, receiving and repeat orders even though they are not material-performance tests.
