Several texts6,7,8 on experimental statistics and standards, describe this test procedure in more detail, provide additional calculations, and discuss methods to compensate for nonnormal distributions see Test Methods D and E AQF Operations team Our team consists of supervisors specialized in various types of products.
ISTA 1A is a procedure designed to challenge the strength and robustness of the product and package combination. If the carton does not protect the products well enough, damage during transport may occur.
Suppliers rejection of the drop test of loaded containers Many supplier refuse to perform a carton drop test during inspections. Replicate samples should be subjected to identical procedures for comparison and for statistical analysis.
Typical types of drop cycles are as follows: If there are more passes than failures, compute the arithmetic mean of the height of the failures and subtract 1? The height of each drop is thus determined by the result of the previous test. Quality Management Product Testing: Quality control inspection companies often simply refer to it as the carton drop test.
Dry and age sufficiently so that any adhesive, protective coatings, sealing tape, and so forth will have reached their?
Asrm 49 —Transportation 49 CFR 4 3. Sometimes the drop height, test cycles, and detailed procedures are prescribed in a contract, regulation, or some other standard.
Shortcomings of the drop test of loaded containers ISTA 1A is a procedure designed to challenge the strength and robustness of the product and package combination. Other times a detailed test plan must be determined based on the engineering and business judgments of the interested parties. GPO, d576, Chapter This test method may also permit observation of the progressive failure of a container and the damage to its contents.

Where a hazard other than that speci? Inspection Process View All. If there are more failures than passes, average the height of the passes and add 1? Your comments will receive careful consideration at a asm of the responsible technical committee, which you may attend.
A normal distribution cannot be assumed for statistical analysis; a log-normal or Weilbull distribution are often better. The drop height, package orientation, and cycle may be chosen based upon knowledge of the shipping environment, knowledge of the type and severity of drop needed to cause certain types of damage to the package or contents, or previous testing or?
If it fails, the next test will be a lower drop height. The pooled reproducibility between laboratory standard deviation was 2.
