How to approve furniture surface resistance
Approve a written exposure schedule and appearance limits before testing. Use panels made with the production substrate, finish and curing process; record exposure, cleaning and recovery conditions, then compare with untouched controls. Agree failures and retesting before release. Cambridge China Bridge can coordinate these checks with its staff in China.
Define what the finish must withstand
Describe the intended use of each surface: dining tops, bedside shelves and cabinet fronts face different exposures. List likely spills, hot objects and household cleaners, together with the care instructions you intend to supply. Replace vague claims such as “stain resistant” with named exposures and agreed outcomes.
Identify the substrate, veneer or decorative layer, coating system, colour, sheen and edge treatment. Keep grain and colour approval separate from resistance approval; use furniture veneer and grain matching for those appearance decisions.
Write a reproducible exposure schedule
For every trial, agree the test location, panel conditioning, finish cure state, exposure duration, cleaning procedure and recovery period before assessment. Ask the laboratory to propose a suitable method and document its scope and any departures. Record actual conditions alongside the agreed settings so a result can be reproduced.
Keep spill exposure, hot-object contact and repeated cleaning as distinct trials. Dry heat and heat with moisture should have separate conditions. If combined exposure reflects expected use, add a separate sequence rather than reusing an already damaged area without recording it.
| Exposure | Conditions to record | Changes to inspect |
|---|---|---|
| Staining liquids | Named liquid, concentration, quantity, covered or uncovered contact, dwell time and removal method | Colour change, rings, whitening and residue after cleaning |
| Hot objects | Contact temperature, object material, contact area, load, duration and dry or moist interface | Gloss change, imprint, blistering, cracking and softening |
| Household cleaners | Exact product, dilution, application amount, dwell time, cloth, wiping pressure, repetitions and rinsing | Haze, colour transfer, tackiness, loss of gloss and coating lift |
Agree appearance limits before seeing results
Define acceptable and unacceptable changes against an untouched control panel. Specify lighting, viewing angle and distance, and whether assessment takes place after cleaning, after recovery, or at both stages. Record stain marks, colour and sheen changes separately from swelling, cracks, blisters, peeling and persistent tackiness.
Use labelled examples of acceptable and rejected results, with photographs and retained physical panels where practical. State whether any visible mark is acceptable and who resolves borderline cases. Link these decisions to your visual defect limits, while keeping exposure conditions attached to each resistance result.
Trial panels from the production process
Use panels selected from the actual production run, with traceable substrate, coating batch and curing records. Include relevant colours, sheens, edges and joints; a flat face panel does not demonstrate edge performance. Agree coverage with the laboratory where finishes differ. Read pre-production and production samples when deciding what the sample represents.
Record when coating, curing, testing and assessment occurred. Keep untouched controls from the same run and label every exposed area. Request photographs before exposure and after cleaning and recovery, plus raw observations. Prevent special polishing, extra curing or unrecorded touch-ups from making the trial panels unlike shipped goods.

Connect approval to release and care instructions
Have the person conducting cleaner trials read the full product label before use. HSE advises that this helps users understand hazards and protect themselves and others. Select cleaners consistent with the proposed furniture care instructions, and record their exact identity rather than describing them only as mild or household products.
Issue a written approval tied to the tested finish and production records. If a result fails, hold the affected release, investigate the cause and retest representative panels after the correction. Require renewed review after changes to substrate, coating or cure process. Use test report coverage to check that the evidence matches the ordered goods.
Frequently asked questions
What temperature should furniture heat tests use?
Agree it from the intended use and the laboratory’s proposed method. Record contact temperature, duration, object material and moisture conditions. A claim that a top tolerates hot cups needs defined conditions.
Can I test only a showroom sample?
Use it for an initial comparison, then trial traceable production panels. A showroom sample may have a different coating, cure history or preparation from the goods you receive.
Which household cleaners should I test?
Name the products customers are expected to use under your care instructions. Record dilution, dwell time, wiping and rinsing. Include repeated cleaning where relevant, and read each product label before use.
What should I do if the finish leaves a ring?
Compare it with the agreed appearance limit after the specified cleaning and recovery. Record the result, hold affected release if it fails, investigate the cause and retest production panels after correction.
