How to Certify a Product Line: Don’t Stop at One Tile
Different finishes can deliver different slip ratings – even within the same product range. AS 4586–2013 testing must reflect what’s actually sold.
You wouldn’t certify a paint range by testing just the white. So why test only one tile finish?
Under AS 4586–2013, certification is only valid for the surface actually tested. If you offer the same tile in matt, gloss, honed, structured, or sealed variants, each may need its own test.
Here’s why:
- Gloss or sealers can reduce friction
- Structured surfaces may trap moisture
- Batch or pigment changes can alter texture
We’ve seen variations of the same tile test anywhere from P2 to P4. Certifying just one version is a shortcut that risks misrepresentation.
Zerofal helps clients structure efficient test plans:
- Group similar finishes to streamline booking
- Label and track each sample for reporting
- Deliver clear outcomes per finish or coating
This protects your brand, helps specifiers make correct decisions, and ensures you’re audit-ready.
Certifying a range?
Contact Zerofal to set up bundled AS 4586–2013 tests across finishes, coatings, or gloss levels.
No. Certification under AS 4586–2013 only applies to the exact finish tested. Other finishes, such as gloss, matt, honed, or sealed, may have different slip resistance ratings.
Surface treatments affect friction. Gloss or sealers can reduce grip, structured surfaces may trap water, and even pigment or batch changes can alter the result.
In practice, the same tile range can produce results anywhere from P2 to P4 depending on finish and coating.
Zerofal creates bundled testing plans, groups similar finishes to save costs, and delivers clear certification reports for each variant—ensuring compliance and reducing audit risk.
