Vertical-flame exposure
Exposes a vertical textile specimen to a burner flame for 12 s.
Tests the required fabric directions and cleaning conditions.
ASTM D6413/D6413M
Vertical-flame test for textiles
Requirements & test methods
ASTM D6413/D6413M-22 measures textile response to a controlled vertical-flame exposure.
Flame-response measurements
Measures afterflame and afterglow duration, then char length under the prescribed tearing load for the specimen mass.
Individual values and averages, plus melting or dripping observations:
| Measurement | Unit |
|---|---|
| Afterflame duration | s |
| Afterglow duration | s |
| Char length | mm or in. |
