TCCA tablets damaged in transit: separating compression and packaging effects

Trial design and interpretation

Compare the dispatch retain and an arrival sample from the same lot using the same weighing and sieving procedure. Record fragments and damage to the outer pack, liner or stack. Investigate tablet strength and transit damage separately.

Recording Tablet weight and diameter

Tablet weight and diameter: use the agreed method. Record breakage after transport. Apply tablet criteria only to tablets. Available chlorine: use the agreed method. Compare the batch result for the same form with the purchasing limit.

What if the bulk delivery contains more fragments than the sample?

Agree the fragment definition, sampling locations and acceptable fraction in the contract. Photograph the opened drum and compare with the retained dispatch sample. Tablet feeder compatibility: Check tablet diameter, mass, strength and operating records against the material and sizes specified by the equipment manufacturer.
