Testing at the receiving site after equipment delivery, covering the system in its operating environment and its interfaces.
Also called: site acceptance testing.
How is SAT different from FAT?
SAT evaluates the system at the user’s installation after the relevant installation and commissioning work, as defined in the agreement. The installed-site context distinguishes it from a factory test; the scope, sequence and contractual acceptance conditions still need to be agreed.
Use the FAT record to identify what changed during delivery and installation. State whether SAT covers a standalone machine or the connected line, including its final upstream and downstream interfaces.
Record the installed configuration, interfaces, product and format, conditions, acceptance criteria and results. Distinguish observations made at the site from earlier FAT results referenced in the report.
Keep technical evidence and commercial consequences distinct. Billing milestones, permission to ship and contractual acceptance depend on the actual agreement. SAT also should not be treated as automatic evidence for every future product or format, or as a substitute for any separately applicable qualification work.
