Scoring Guide — Tire Inflator / Repair

Step 1: Determine Q1 classification

Q1 = electronics if the product is a powered portable compressor/inflator (corded 12V, AC, or cordless battery). This includes combo kits where the inflator is the primary component.

Q1 = chemical if the product is an aerosol or liquid tire sealant (Fix-a-Flat style cans, liquid bottle sealants).

Record Q1 as product_kind in the product frontmatter.

Step 2: Quality scoring

Electronics path: Follow quality.md Electronics Track (tire-inflator dimensions). Research:

1. Community fill-time measurements (YouTube, forum threads — not manufacturer claims)
2. Gauge accuracy cross-comparisons (community vs. reference gauge)
3. Safety certification: UL Product iQ, Intertek ETL, CPSC, FCC databases
4. Build quality: long-term reviews (1–3 year follow-up), thermal behavior reports
5. Convenience features: auto-shutoff accuracy, display readability, hose length
6. Power/PSI: community-confirmed max PSI at target pressure

Aerosol/Chemical path: Follow quality.md Aerosol/Sealant Track:

1. Seal effectiveness: community reviews documenting hold time (not just "it worked")
2. Inflation adequacy: PSI achieved, community measurements
3. TPMS safety: manufacturer claim + community follow-up on sensor status
4. Ease of use: emergency usability reports
5. Coverage/size: can volume vs. target tire category

Step 3: Health scoring

Electronics: Base 9.0, apply deductions from health.md Electronics Path. Check CPSC recall. No SDS hunt needed.

Chemical: Source SDS first. Use SDS-Sources.md decision tree. For Fix-a-Flat: brand is ITW Global Brands; SDS may be available at itw.com or chemicalsafety.com. For Slime: slimedirect.com or chemicalsafety.com. Once SDS is in hand:

1. Extract signal word and GHS pictograms
2. Identify H-codes → separate PHYSICAL hazards (H222, H229) from HEALTH hazards
3. Apply deductions from health.md Chemical Path only for health H-codes
4. PPE: determine tier for eyes, skin, lungs based on H-codes (not boilerplate)

Step 4: Environment scoring

Electronics: Apply tire-inflator 3-dimension or 4-dimension path depending on power type.

Chemical: Apply environment.md Aerosol/Chemical Path 3-dimension scoring (VOC, packaging, formula).

Step 5: CCT opinion

Apply regardless of Q1. Honest editorial verdict: does this product earn a recommendation?

Aerosol sealants: Most receive opinion 5–7. Reserve 8+ for products with exceptional TPMS safety, eco-formula credentials, AND community-confirmed seal reliability. Never write opinion >7 for a sealant that doesn't explicitly claim TPMS safety — TPMS damage is too common a failure mode.

Electronics/inflators: Follow tire-inflator opinion calibration. Combo kits earn a bonus (opinion +0.5 above standalone inflator of same quality) if the bundled repair kit is meaningfully complete.

Step 6: Validate and sanity check

Before finalizing:

1. Did flammability codes (H222, H229) contribute to health? They should contribute 0.
2. Does the CCT composite match the formula result? Check: (quality × 0.75) + (health × 0.15) + (env × 0.10) for formula, then (formula × 0.75) + (opinion × 0.25) for composite.
3. Does the badge match the composite? (≥7.0 = Recommended, ≥8.3 = Top Pick)
4. For aerosols: is the SDS signal word in frontmatter? It should reflect the actual signal word from the SDS (WARNING or DANGER based on chemistry), not be suppressed because H222 drives DANGER from flammability only.

CRITICAL for aerosols: If DANGER is driven only by H222/H229 (physical hazards), the signal_word: danger should still appear in frontmatter (it's the actual SDS signal word), but the health score must NOT deduct for it as if it were driven by a health H-code. Document this explicitly in notes.md.
