FAT / SAT Protocols
Acceptance you can verify, not just sign
Every YanMao line passes two written acceptance gates. Both are run from published checklists, filmed, and signed jointly — so “accepted” means the same thing to both sides.
Phase 1
FAT — 3 days at our factory
Run from the written checklist, filmed, with your engineers present or remote. No surprises before shipping.
Phase 2
Cratering & shipping
Machines leave in export-grade crates with humidity protection and full tracking to your port.
Phase 3
Installation — 5–7 days at your site
Our team (or a certified partner) installs, aligns and commissions the line with your crew.
Phase 4
SAT — sign-off at rated speed
Joint acceptance against the same standard used at FAT. Warranty starts only after you sign.
Factory Acceptance Test
What we test before your machine ships
- Machine safety circuits tested per EN 60204-1 with third-party witness option
- Continuous run at rated speed for 4 hours with zero unscheduled stops
- Product changeover timed and recorded for every format agreed in the PO
- Case quality audit — squareness, flap alignment, glue pattern per sample log
- Sample packs logged with date, lot and line speed for your QC records
- Electrical and pneumatic drawings marked up to match as-built hardware
- Spare parts, tooling and documentation verified against the packing list
- Full video evidence recorded and shared before your team signs
Your project engineer joins the FAT live or via video. Every test is filmed and archived — if an item fails, it is corrected and re-run before the crate is sealed.
Site Acceptance Test
What we prove on your floor
- Site preparation review — leveling, utilities, access and safety zones
- Installation and alignment per the machine manual, with level readings
- Safety guards, interlocks and light curtains functionally tested
- Two days of hands-on operator and maintenance training at your site
- Production trial at agreed speed with your product and your operators
- Quality samples jointly inspected and signed off
- IQ/OQ documentation handed over (GMP/21 CFR Part 11 projects)
- SAT sign-off, warranty start date confirmed and training certificate issued
Your operators run the line during SAT. The acceptance document records measured speeds, changeover times and samples — and it activates your warranty, not before.
