GB/T 18801 vs F8

FINAL CERTIFIED VERSION — GB/T 18801 vs "F8"

EXECUTIVE SUMMARY

Query pairs GB/T 18801 (空气净化器 / Air Cleaners) with "F8" — not a valid standard pair. GB/T 18801-2022 is a TIER 1 product standard; "F8" is a filter efficiency class (EN 779:2012 fine-filter band), not a standard number. Both drafts agree on this disambiguation. Procurement implication: buyer must confirm whether they need air-cleaner product compliance (GB/T 18801) or filter-media compliance (GB/T 14295 / ISO 16890 / EN 1822) — these are different procurement tracks.

APPLICABLE CHINESE STANDARDS

STANDARD TIER CLASSIFICATION

⚠️ TIER MISMATCH FLAG: Comparing GB/T 18801 (TIER 1 product) directly to "F8" (a TIER 4 class label) is a category error. Valid comparison requires GB/T 14295-2019 (TIER 4) ↔ EN 779:2012 (TIER 4).

SCOPE BREAKDOWN

Sub-category A — Air Cleaner Product (whole appliance)

Chinese standard: GB/T 18801-2022: 空气净化器 (Air Cleaners)

International equivalent: AHAM AC-1 (US, edition verify) / no single ISO equivalent — ⚠️ no IDT counterpart

Equivalence: NEQ

Standard tier match: Both TIER 1 (product) — valid comparison

Sub-category B — Filter Media / Filter Class (the "F8" track)

Chinese standard: GB/T 14295-2019: 空气过滤器 (Air Filters)

International equivalent: EN 779:2012 (F8 class) — ⚠️ withdrawn in EU, replaced by ISO 16890-1:2016

Equivalence: NEQ (different classification basis)

Standard tier match: Both TIER 4 — valid comparison

⚠️ Draft disagreement: A stated F8 = "average arrestance/efficiency band" without numbers; B stated "90% ≤ Am < 95%". B is more specific but self-flagged uncertainty. Do not rely on the numeric band until EN 779:2012 §5 is confirmed.

KEY DIFFERENCES SUMMARY

• Standard identity — GB/T 18801 is a product standard; "F8" is a filter class. Not comparable. → 不可互认 (Not mutually recognised). HIGH.
• Classification basis — GB/T 14295 uses 粗/中/亚高效/高效 (coarse/medium/sub-HEPA/HEPA); EN 779 uses G/M/F. No 1:1 mapping. → 不可互认 (Not mutually recognised). HIGH.
• Test aerosol/method — differs between CN and EN filter tests. → 附加测试后互认 (Mutual recognition after additional testing) only if both test reports supplied. HIGH.
• CCM — China-only parameter, no international counterpart. → 不可互认 (Not mutually recognised). MEDIUM.

REGULATORY LINKAGE TABLE (法规联动)

AUDIT FLAG RESOLUTION

• ✅ RESOLVED: "F8" is a filter class, not a standard — both drafts concur.
• ⚠️ UNRESOLVED: F8 numeric band (90–95% Am) — verify against EN 779:2012 §5.
• ⚠️ UNRESOLVED: GB/T 14295-2019 class table — verify §5.
• 🔴 CRITICAL CORRECTION: Any report treating "GB/T 18801 vs F8" as two standards is invalid — reclassify per Sub-categories A/B above.

PROCUREMENT VERDICT

• Confirm intended scope: air cleaner (GB/T 18801) or filter media (GB/T 14295 / ISO 16890).
• If filter: obtain EN 779:2012 §5 class table and GB/T 14295-2019 §5 class table; map explicitly.
• Require test reports stating aerosol and method — no cross-recognition without them.
• For air cleaners: require GB/T 18801-2022 CADR + CCM report; do not accept AHAM CADR as equivalent.
• Verify GB 21551.3-2010 compliance if antibacterial claims are made.

REFERENCE DOCUMENT CHECKLIST (配套调阅清单)

• GB/T 18801-2022 §5–6 — CADR, CCM test methods
• GB/T 14295-2019 §5–6 — filter class table, test aerosol
• EN 779:2012 §5–6 — F8 class definition, test method
• ISO 16890-1:2016 §5 — ePM classification
• GB 21551.3-2010 — antibacterial claim requirements

FIELD INSPECTION CHECKLIST

• Verify filter label class against test report (not marketing "F8").
• Confirm test aerosol and particle size in report.
• Check air cleaner CADR/CCM report edition (2022, not 2015).
• Confirm antibacterial claims backed by GB 21551.3-2010 test.

CONFIDENCE RATING

🟡 MEDIUM — disambiguation verified across both drafts; F8 numeric band and GB/T 14295 class table flagged for official-text confirmation.
