Who determines pass or fail of testing results?
These determinations are dependent upon the particular product, package, distribution system, market, customers, and other factors and can vary widely. Therefore product damage and allowable package degradation must be defined by the shipper, manufacturer, damage claim group, and/or other stakeholders and interested parties. In most cases, the shipper/manufacturer is in the best position to define product damage due to detailed familiarity with the product. Sometimes others may contribute to these determinations, including carriers and test lab personnel. But in any case, definition and agreement should be reached cooperatively among all entities concerned with safe arrival of the shipment, low damage rates, cost effective packaging, etc.
What are the benefits of random vibration testing vs. fixed-displacement testing?
The answer, in a nutshell, is "better simulation of the actual transport environment". Fixed displacement vibration has been around for over 60 years, and was the first type of vibration ever used for packaged-product testing. In reality, it was ...
What test should I select for ocean shipments?
ISTA Procedures, and other industry-standard packaging test protocols, don’t contain vibration (PSD) profiles for ocean shipment. Several studies have shown that vertical vibration during sea transport is so small that it’s negligible. This is not ...
What is meant by “fixturing” in regards to vibration testing?
As stated in ISTA testing protocols, "Restraining devices shall be used to... (1) Prevent the test specimen from moving off the platform and (2) maintain test orientation of the packaged-product, but (3) not restrict the vertical motion of the test ...
In order to pass an ISTA test procedure do all test methods need to be passed?
When performing an ISTA test procedure or project that will be submitted for ISTA recognition or certification, all required test methods, at the required minimum test levels, must have passed. If there is a method performed during the testing that ...
Which ISTA test should I use?
This common question cannot be answered directly, but must be determined in each case through an understanding of the various ISTA tests and their applications. Please click the following link for more information including a "Test Selection ...
