3.  DEFINITIONS

3.1  General definitions.  The following are the definitions for the two classifications of defects used in this standard. Note that some definitions may apply primarily to only round/ballistic type parachutes or only to gliding/ram-air type parachutes or to both.

3.1.1  Major/Critical defect.  A defect that is likely to result in failure or to reduce the usability of the unit of product for its intended purpose.  A major/critical defect is also defined as a dimension out of tolerance, component and or construction deviation which may adversely affect the fit, form or function of the parachute assembly.

3.1.2  Minor defect.  A defect that is not likely to reduce the usability of the unit of product for its intended purpose or is a departure from established standards having little bearing on the effective use or the operation of the unit.

3.2  Specific definitions of parachute terms.

3.2.1  Adapter.  A rectangular metal fitting with a crossbar incorporated in a parachute harness to permit proper adjustment of harness.

3.2.2  Adapter, harness quick fit.  An adapter in which a floating friction grip is used in lieu of a fixed crossbar.

3.2.3  Apex.  The center and top most point of an inflated round  parachute canopy.

3.2.4  Back pad.  A pad attached to the inside of the harness to provide comfort for the wearer and help keep the harness in place.

3.2.5  Back strap.  Part of the harness webbing extending across the back of the wearer. It may or may not be adjustable.

3.2.6  Bag, deployment.  A type of container made of fabric and webbings in which a parachute canopy is packed.

3.2.7  Band, lateral.  Webbing inserted in the hem of parachute canopies to reinforce

edges of fabric and distribute the load.  The lower lateral band is inserted in the skirt hem and the upper lateral band is inserted in the vent hem.

3.2.8  Band, pocket.  A piece of textile tape or line attached at the outside of the skirt across main seams in such a manner as to cause the gores to be pulled outward at inflation.

3.2.9  Band, reinforcement.  A tape or a ribbon inserted in various positions to reinforce weak points in a canopy.

3.2.10  Band, retainer.  A rubber band used to hold folded suspension lines or static lines to deployment bags or parachute packs.
