An extensible absorbent article for wearing in the crotch region of an undergarment, said absorbent article having a longitudinal centerline, a transverse centerline, a liquid pervious side, a liquid impervious side, and an absorbent component positioned between said liquid pervious side and said liquid impervious side, wherein:
- (a) a 1.0 inch wide strip having an initial length is cut from a longitudinal section of a first sample absorbent article that is centered about said longitudinal centerline is capable of extension of greater than or equal to about 110% of its initial length when subjected to a force of less than or equal to about 500 grams;
- and
- (b) a 1.0 inch wide strip having an initial length is cut from a transverse section that runs parallel to the transverse centerline of a second absorbent article of the same type as the first absorbent article is capable of extension of greater than or equal to about 110% of its initial length when subjected to a force of less than or equal to about 400 grams.

- (a) a first 1.0 inch wide strip having an initial length is cut from a longitudinal section of a first sample absorbent article that is centered about said longitudinal centerline is capable of extension of greater than or equal to about 110% of its initial length when subjected to a force of less than or equal to about 500 grams;
- and
- (b) a second 1.0 inch wide strip having an initial length is cut from a transverse section that runs parallel to the transverse centerline of a second absorbent article of the same type as the first absorbent article is capable of extension of greater than or equal to about 110% and less than or equal to about 140% of its initial length when subjected to a force of less than or equal to about 400 grams.
An extensible absorbent article for attaching to and wearing in the crotch region of an undergarment, said absorbent article having a longitudinal centerline, a transverse centerline, a liquid pervious side, a liquid impervious side, and an absorbent component positioned between said liquid pervious side and said liquid impervious side, wherein:
- (a) a first 1.0 inch wide strip having an initial length is cut from a longitudinal section of a first sample absorbent article that is centered about said longitudinal centerline is capable of extension of greater than or equal to about 110% of its initial length when subjected to a force of less than or equal to about 500 grams;
- and
- (b) a second 1.0 inch wide strip having an initial length is cut from a transverse section that runs parallel to the transverse centerline of a second absorbent article of the same type as the first absorbent article is capable of extension of greater than or equal to about 110% and less than or equal to about 140% of its initial length when subjected to a force of less than or equal to about 400 grams.
