A red brick floor tile sourced from China should be evaluated through two separate tracks: verified origin and measurable slip performance. Country of manufacture does not prove traction, and “anti-slip” does not describe a wet test method, classification or intended location. Both tracks need current, traceable records.
Verify product and supply identity separately
Request the current product code, drawing, body and finish description, dimensions, tolerances, mass and intended applications. Separately identify the legal seller, actual manufacturing facility, exporter where different and party responsible for technical evidence. Similar names or an archive country label do not establish that chain.
Tie the drawing, quotation, samples, reports, packing and order to the same product and facility revision. Require written review for a change in body, finish, factory or evidence. A visually similar red tile may not carry the same slip result.
Complete the supplier and transaction due diligence required by the buyer’s organisation and destination through qualified parties. A factory address, audit or certificate can support selected checks, but it does not replace contract accountability, exact-product evidence or shipment inspection.
Write a wet-use brief
Describe whether the floor is interior or exterior, covered or exposed, level, ramped or stepped, barefoot or shod, and subject to rain, cleaning water, food, oils or tracked soil. Map drains, entrances and routes where moisture accumulates. Define users, traffic and accessibility requirements.
The responsible designer should establish the applicable slip method, test condition and acceptance classification for each zone. Avoid one anti-slip requirement across dissimilar uses. A dry corridor result cannot automatically answer an exposed ramp or entrance condition.
Record how quickly water should leave the surface and what happens during blockage, intense cleaning or wind-driven rain. Drainage design, floor geometry and operations should reduce exposure; a textured tile should not be the sole control for persistent wetness.
Read slip evidence in context
Exact surface
Match code, texture, finish, colour family, treatment and production basis to the tested specimen.
Test condition
Check method, contaminant or wet condition, preparation, direction and reported classification.
Report scope
Verify laboratory, date, specimen identity, limitations and relevance to the destination requirement.
In-service change
Consider wear, dirt, residue and cleaning without turning a laboratory result into a lifetime guarantee.
Do not infer antibacterial, acid, wear or fire performance from a slip report, and do not use a management-system certificate as product evidence. Map each requirement to its own current document or project trial.
Build procurement QA around traceability
Approve labelled samples showing the red fired range and exact surface. Define production-lot identification, inspection rights, sampling, dimensions, appearance, damage and document checks. Keep duplicate controls with designated parties where practical, because photographs alone are unreliable for subtle texture and colour.
Before shipment, reconcile product code, quantity, lot, reports, packing and release status. Confirm carton and pallet information, weather protection, handling and delivery responsibilities. At receipt, record damage, shortages and lot references before pallets are dispersed.
Set document gates for sample approval, production release and shipment. Record translations and revision status where used. Resolve discrepancies among a report, sample label, drawing and invoice before material moves, when corrective options remain wider.
Coordinate drainage and the whole floor
The project team should define structure, substrate, falls, drainage, waterproofing where required, bedding or adhesive, joints, movement, edges and thresholds. Standing water, lippage, rocking units or contaminated joints can create hazards regardless of the tile’s initial test result.
Separate pedestrian and service or vehicle duties. Protect completed work from grit and construction traffic. Provide entrance control, drainage and cleaning measures appropriate to the use rather than expecting the surface texture to compensate for an incomplete design.
Approve colour, cleaning and slip together
Build a representative mock-up with the intended bond, joints, batches, drainage interfaces and lighting. Review the red range dry and wetted where relevant. Trial realistic contaminants and the proposed cleaning process, then reassess residue, appearance, joints and traction.
If a sealer or treatment is proposed, include it in approval and evidence or obtain appropriate review. Record product, application and maintenance. A treatment may change colour or slip, so it cannot be added as an invisible commercial substitution.
Repeat the approved cleaning cycle enough to reveal residue or progressive change appropriate to the project review, without presenting the trial as a service-life prediction. Keep untreated and treated control samples clearly labelled for comparison.
Release an evidence-linked order and handover
Align current product and facility identity, drawing, approved red range, slip criteria, evidence, floor build-up, layout, quantities, batches, spares, packing and programme. Record change approvals and installed lot locations. Keep nonconforming material separate until disposition is agreed.
At handover, retain final documents, cleaning method, inspection intervals, repairs and labelled spares. Review the current terracotta floor tile range and flooring archive for options, then verify origin and performance independently.
