Specifying office carpet tiles (方块地毯 / commercial carpet squares) for a corporate fit-out involves more than matching a color to the wall. The difference between a floor that looks good after 8 years and one that mats down in 18 months often comes down to five line items on the Technical Data Sheet (TDS). This guide helps procurement managers, architects, and facility teams specify carpet tiles that pass fire codes, resist crushing, and minimize lifecycle cost.
1. Face Fiber — Insist on Solution‑Dyed Nylon 6,6 for Heavy Traffic
- Nylon 6,6 (PA66): Tighter molecular chain → superior crush recovery under castor chairs, higher melt point (~255°C), excellent colorfastness. First choice for open‑plan offices and corridors (Class 33).
- Nylon 6 (PA6): Acceptable for light commercial (Class 32) but less resilient.
- Polypropylene (PP/Olefin): Budget option; low abrasion resistance, melts ~165°C — suitable only for low‑traffic back offices.

2. Wear Classification — EN 1307 / ISO 12951‑2
| Class | Usage |
|---|---|
| Class 33 — Heavy Commercial | ✅ Standard for open‑plan offices, banks, gov’t buildings |
| Class 32 — General Commercial | Small meeting rooms, hotel guestrooms |
| Class 31 — Moderate Commercial | Domestic / light use only |
Always request Class 33 + 10‑yr wear warranty on premium lines.
3. Pile Weight & Construction
- Loop Pile (3.5–5.0 mm): Best soil‑hiding & durability for offices.
- Pile Weight: ≥ 550 g/m² for nylon tile; anything lower risks premature crushing.
- Tuft Bind Strength: ≥ 10–12 N — prevents fuzzing / yarn pull‑out.
4. Backing & Dimensional Stability
- PVC Unitary Backing: Industry standard; B1 fire rated; moisture‑stable.
- Cushion / Acoustic Backing: Improves ΔLw (impact sound reduction) — good for floors above occupied spaces.
- PVC‑Free (PE/EVA): Required for LEED / WELL Platinum submissions.
5. Fire & Indoor Air Quality
- Fire: GB 8624‑2012 Class B1 (≡ Euroclass Bfl‑s1). Obtain original CNAS/SGS test report.
- IAQ: Specify CRI Green Label Plus / FloorScore® / F4‑Star low‑VOC products — supports WELL IEQ credits.
6. Lifecycle Advantage — Selective Replacement
Retain 3–5% spare tiles. Damaged tile(s) can be lifted and replaced without disturbing adjacent tiles or adhesive — extends aesthetic life 3–5 yrs vs broadloom.
Quick Buyer Checklist
- [ ] Solution‑dyed Nylon 6,6 face fiber?
- [ ] Wear Class 33 Heavy Commercial?
- [ ] Pile wt ≥ 550 g/m², loop pile?
- [ ] PVC or cushion backing, tuft bind ≥10 N?
- [ ] B1 (GB) / Bfl‑s1 fire cert + CRI Green Label Plus?
- [ ] Supplier provides 3–5% matching spares?
Choosing the correct office carpet tile is an investment in acoustics, safety, and 10‑year appearance retention — not just décor.
