What does a buyer check before specifying tiles?
They check the technical classification and water absorption against the application, the slip resistance rating for the location, and batch and shade consistency. Slip resistance is a liability question in commercial projects, so it is checked before appearance.
A specifier is selecting tiles for a wet commercial area where a slip claim would be traced back to the specification.

Scope and specifications
- Tile type and technical class
- Porcelain, ceramic and natural stone perform very differently.
- Water absorption class
- Determines suitability for external and wet areas.
- Slip resistance rating
- A liability specification in commercial and wet areas.
- Breaking strength and thickness
- Governs suitability for floors and traffic levels.
- Dimensions and rectification
- Rectified edges change the joint width and the look.
- Shade variation grade
- Sets the buyer's expectation about batch appearance.
- Frost resistance
- Essential for external use in cold climates.

Questions suppliers ask
Why is slip resistance the first technical check in commercial work?
Because a slip injury is traced back to the specification, and the specifier carries the exposure. Publishing the rating and the test method for every tile makes your range usable in commercial projects; omitting it confines you to domestic work.
How should shade variation be handled?
By publishing the variation grade for each product and explaining what it means. Tiles genuinely vary between batches, and setting the expectation in advance converts a normal characteristic into an understood feature rather than a complaint at handover.
Should full technical data be public or supplied on request?
Public. Specifiers filter by absorption, slip and strength class, and a range whose data is behind a form is simply not considered. There is nothing confidential in classification data, and it is what makes the product findable.
