Sift Test ProceduresSift Test Procedures

1. Torque Meter measures the torque of a closure on a bottle in inch-pounds.

3. The package is placed into a fixture so that the bottle stays in place when the test is conducted.

4. The configuration is placed into a sieve shaker. The test is conducted for one minute.

2. A Heat Gun is used to shrink the tamper-evident band around the bottle and closure.

Sifting LevelsSifting Levels

Level 3: Dusting – Increased particle count, one layer of beads or product, too many to count.

Level 4: Sifting – Accumulated particles, multiple layers and deposits, possibly measurable by weight.

No sift under the band

Small amount of sift above

the center cleanout

One layer of product above the front curve

Multiple layers of product above the

front curve

Level 1: No visible siftLevel 2: Particles – Visually definable individual

media glass beads or product, plenty of space surrounding product, countable.
