Materials classified 94V-1 shall:
• Not have a total flaming combustion time exceeding 250 seconds for the 10 flame applications for each
• Not have any specimens which burn with flaming or glowing combustion up to the holding clamp.
• Not have any specimens which drip flaming par ticles that ignite the dry absorbent surgical cotton located
• Not have an specimens with glowing combustion which persists for more than 60 seconds after the
Materials classified 94V-2 shall:
• Not have any specimens which burn with flaming combustion for more than 30 seconds after either
• Not have a total flaming combustion time exceeding 250 seconds for the 10 flame applications for each set
• Not have any specimens which burn with flaming or glowing combustion up to the holding clamp.
• Be permitted to have specimens which drip flaming particles which burn only briefly some of which ignite
• Not have any specimens with glowing combustion which persists for more than 60 seconds after the
• Specimens shall have a maximum burn rate of 1.5 in./min over 3 inches of thickness of 0.120" to 0.5".
• Specimens shall have a maximum burn rate of 2.5 in./min over 3 inches for a thickness less than 0.120".
Samples of fully recovered tubing are placed over a length of fine spring steel music wire. The test requires
the precise placement of a controlled flame that contacts the heat shrink tubing. The flame is applied in five
fifteen second intervals with a time period between applications. If the flame extinguishes immediately after
the first flame removal, subsequent flame applications are made to the tubing. Duration of specimen flaming
is noted. A piece of surgical cotton is placed under the specimen. If a flaming or glowing piece of tubing
drips and ignites the cotton, this is also noted.
• Not flame or glow longer than 60 seconds following any of the five applications of the flame.
• Not ignite or damage more than 25% of kraft paper flag that is placed around the top of the tubing.
• Not have any specimens which drip flaming par ticles and ignite the surgical cotton located 9 1/2 inches
