Quality Control & Testing Flashcards

What is the primary purpose of ISTA (International Safe Transit Association) testing protocols?

Answer: Simulate real-world distribution hazards to verify package performance

ISTA protocols simulate the shock, vibration, and climate hazards packages encounter during actual distribution.

In a corrugated box compression test, what does BCT stand for?

Answer: Box Compression Test

BCT (Box Compression Test) measures the maximum load a filled corrugated box can withstand before collapsing.

Which gas analysis method is most commonly used to measure headspace oxygen in modified atmosphere packages?

Answer: Portable headspace analyzer with electrochemical sensor

Portable headspace analyzers with electrochemical oxygen sensors are the most practical and common method for MAP quality control.

A control chart with all points within control limits but 9 consecutive points on one side of the centerline indicates:

Answer: A non-random pattern suggesting a process shift

Nine consecutive points on one side of the centerline is a Nelson/Western Electric run rule indicating a non-random process shift.

What does OTR measure in packaging material testing?

Answer: Oxygen Transmission Rate

OTR (Oxygen Transmission Rate) quantifies how much oxygen passes through a packaging material per unit area per unit time.

Which sampling standard is most widely referenced for packaging inspection by attributes?

Answer: ANSI/ASQ Z1.4

ANSI/ASQ Z1.4 provides sampling procedures and tables for inspection by attributes, widely used in packaging QC.

In seal strength testing, what does a 'peel' test measure compared to a 'shear' test?

Answer: Peel measures force perpendicular to the seal plane; shear measures force parallel to it

Peel testing applies force perpendicular (T-peel or 90°) to open the seal, while shear testing pulls parallel to the seal plane.
