Assumptions & limits
Assumptions & limits
- Sea-level empirical estimate, restricted here to 0–50°C and 5–99% RH. Not a safety or heat-stress decision. Supported limits: All required fields must be finite values of the exact declared type and within displayed bounds. Lists contain1–1000 finite numbers. JSON tables are numeric rectangular rows, at most100 rows and30 columns; individual tools have stricter shape/domain constraints. Sea-level empirical estimate, restricted here to 0–50°C and 5–99% RH. Not a safety or heat-stress decision.
