Definitions of terminologies used for LFMC (Problematic and required characteristics) Hex: Hose is not perfectly round has a slight to extreme hexagon formation. Hair: Slivers of metal slight to extreme protruding from the I.D. or O.D. of the hose. Stay put: When the hose is extended it stays; it does not release back to normal lie. Crunch: When bent the hose does not bend smooth and makes a crunchy noise. Scratch: When bent the hose has a scratchy noise. Rounded convolutions: The top of the convolutions of the hose is not flat but rounded. Drag: The cover while hot rubs or is out of alignment causing <<<<<< appearance in the cover. Half the total lateral movement: Extension has to be equal to or less than half the total lateral movement. Not fully compressed: when compressed the convolutions do not fully compress or touch. Pick off: This is a compound that builds up around the point and comes off onto the cover in lump form. Too much extension: The hose can be extended past the maximum allowed per foot. Minimum extension: The hose has to extend at or past the minimum required amount per foot. Sticky: When extended; the hose has some sticking tendencies but releases back to normal lie. Normal lie: Position of the hose in the relaxed state. Strip burr: Slight burr caused by slitting metal. Bend diameter: Bend measured from the inside of the hose. ∩ Bend radius: Half the bend diameter. Side play: The amount of movement between each convolution side to side. Snaky: When the hose is either extended or compressed fully and it has a zigzag appearance; not straight. Knuckle: When bending back from the required bend diameter it is irregular (not a smooth return). Extension: The amount of distance you can extend the hose in one foot. Compression: The amount of distance you can close up or compress the hose in one foot. Ovalized: When a certain amount of pressure has been applied which causes the hose to be oval or not round. Tool mark: Mark or cut on the core made by tooling that is either out of alignment, chipped or worn. Spring out: The distance that the hose moves after compression back to the extended state. Jerk spot: The covered hose has been yanked which caused a noticeable size variation in the cover. Droop: The distance where compressed conduit droops when slid off the edge of a fixed flat surface. Pattern: There is a noticeable lumpy appearance in the hose which causes size variation every few inches. Spin: Outside diameter growing bigger after compression or sawing has occurred.
