Packaging and storage
Preserve in well-closed,light-resistant containers,in a cool place.
Identification
The retention time of the major peak in the chromatogram of the
Assay preparationcorresponds to that in the chromatogram of the
Standard preparationas obtained in the
Assay.

Medium:
water;500mL.
Apparatus 2:
50rpm.
Time:
15minutes.
Procedure
Place 1Capsule in each vessel,and allow the Capsule to sink to the bottom of the vessel before starting rotation of the blade.Observe the Capsules,and record the time taken for each capsule shell to rupture.
Tolerances
The requirements are met if all of the Capsules tested rupture in not more than 15minutes.If 1or 2of the Capsules rupture in more than 15but not more than 30minutes,repeat the test on 12additional Capsules.Not more than 2of the total of 18Capsules tested rupture in more than 15but not more than 30minutes.
