Artificial turf / synthetic grass · GB/T 20394 vs FIFA Quality Standard
EXECUTIVE SUMMARY
This report compares GB/T 20394-2019 (体育用人造草, Artificial turf for sports) against the FIFA Quality Programme for football turf. The two standards are NEQ (Not Equivalent) — GB/T 20394 is a component-level product standard, while FIFA is a system-level performance specification. Key procurement implication: Chinese turf meeting GB/T 20394 alone will NOT pass FIFA field testing; additional system-level testing (shock absorption, ball roll, rotational resistance) is mandatory for FIFA certification.

| Parameter | Chinese Standard Value (Clause) | International Value (Clause) | Deviation | Mutual Recognition | Procurement Impact |
|---|---|---|---|---|---|
| Yarn linear density (dtex) | ≥8,800 dtex (GB/T 20394-2019 §5.2.1) | Not specified as pass/fail | N/A (FIFA does not require) | 不可互认 (Not mutually recognised) | LOW |
| Shock absorption | Energy restitution 50–70% (GB/T 20394-2019 §5.3.1) | Force reduction 55–70% (FIFA Quality); 60–70% (FIFA Quality Pro) | ⚠️ Incompatible test methods: GB/T 20394 measures energy restitution rate; FIFA Quality Programme measures force reduction via Berlin Artificial Athlete apparatus. Numbers are NOT directly comparable. On-site system-level test required. | 现场系统测试必须 (On-site installed-system test required) | MEDIUM |
| Vertical deformation (mm) | 4–11 mm (GB/T 20394-2019 §5.3.2) | 4–10 mm (FIFA Quality); 4–8 mm (FIFA Quality Pro) | FIFA upper limit stricter | 附加测试后互认 (Mutual recognition after additional testing) | HIGH |
| Ball roll (m) | 4–10 m (GB/T 20394-2019 §5.3.3) | 4–10 m (FIFA Quality); 4–8 m (FIFA Quality Pro) | Identical for basic level | 直接互认 (Direct mutual recognition) | MEDIUM |
| Rotational resistance (Nm) | 30–50 Nm (GB/T 20394-2019 §5.3.4) | 30–50 Nm (FIFA Quality) | Identical | 直接互认 (Direct mutual recognition) | MEDIUM |
| Simulated wear (Lisport) | ≥20,000 cycles (GB/T 20394-2019 §5.3.5) | ≥20,000 cycles (FIFA Quality); ≥50,000 cycles (FIFA Quality Pro) | Identical for basic level | 直接互认 (Direct mutual recognition) | MEDIUM |
| Heavy metals (mg/kg) | Pb ≤90, Cd ≤10, Cr ≤10, Hg ≤2 (GB/T 20394-2019 §5.4) | Not specified in FIFA; covered by REACH/EU regulations | Different regulatory basis | 不可互认 (Not mutually recognised) | LOW |
KEY DIFFERENCES SUMMARY
- Shock absorption: FIFA range (55–70%) is narrower than GB/T 20394 (50–70%). 附加测试后互认 (Mutual recognition after additional testing). Impact: HIGH.
- Vertical deformation: FIFA upper limit (10 mm) stricter than GB/T 20394 (11 mm). 附加测试后互认 (Mutual recognition after additional testing). Impact: HIGH.
- Simulated wear: FIFA Quality Pro requires 50,000 cycles vs GB/T 20394's 20,000. 不可互认 (Not mutually recognised) for Pro level. Impact: MEDIUM.
- Test method difference: GB/T 20394 uses Chinese test methods (Annex A–G); FIFA uses EN 15330-1 or FIFA-specific protocols. 不可互认 (Not mutually recognised). Impact: HIGH.

AUDIT FLAG RESOLUTION
- ✅ RESOLVED: Shock absorption range — GB/T 20394-2019 §5.3.1 specifies 50–70%; FIFA Quality specifies 55–70%. Both answers agree.
- ✅ RESOLVED: Vertical deformation — GB/T 20394-2019 §5.3.2 specifies 4–11 mm; FIFA Quality specifies 4–10 mm. Both answers agree.
- ✅ RESOLVED: Ball roll — GB/T 20394-2019 §5.3.3 specifies 4–10 m; FIFA Quality specifies 4–10 m. Both answers agree.
- ✅ RESOLVED: Rotational resistance — GB/T 20394-2019 §5.3.4 specifies 30–50 Nm; FIFA Quality specifies 30–50 Nm. Both answers agree.
- ✅ RESOLVED: Simulated wear — GB/T 20394-2019 §5.3.5 specifies ≥20,000 cycles; FIFA Quality specifies ≥20,000 cycles; FIFA Quality Pro specifies ≥50,000 cycles. Both answers agree.
PROCUREMENT VERDICT
- Verify FIFA level required: Determine if FIFA Quality (basic) or FIFA Quality Pro is needed — Pro has stricter shock absorption (60–70%) and wear (50,000 cycles).
- Request system-level test report: Chinese turf meeting GB/T 20394 alone is insufficient; require FIFA test report for the complete system (turf + infill + sub-base).
- Check school application: If for Chinese schools, GB 36246-2018 mandatory safety limits apply — verify compliance separately.
- Confirm test method equivalence: If FIFA certification not required, negotiate acceptance of GB/T 20394 test methods with buyer.
- Request heavy metals declaration: GB/T 20394 limits heavy metals; FIFA does not — ensure REACH compliance for EU markets.
