Flash point calculator — GHS flammable liquid category
A free flash point calculator for GHS classification: flammable-liquid category is a mixture-level property — based on the blend's own flash point (and initial boiling point), not a sum of component categories. Enter the flash point to get the GHS category (1–4), H-code, signal word and pictogram.
Deterministic calculation from the data you enter. A draft result for review by a qualified professional — not a compliance determination. Nothing is stored.
Tired of transcribing hazard data off your supplier SDSs? Sign up and extract it automatically from the actual SDS — which also captures supplier-specific impurities a manual entry can't.
Classify the whole mixture, not one endpoint
GHSLogic runs every GHS endpoint from your real supplier SDSs, then drafts a review-ready SDS and labels — with the rule path behind every result.
