Generally, this type of testing is applicable to any product with an exposed metal surface. It’s especially applicable to products that are meant to be used outdoors and will likely be exposed to the elements. For items that may not be used outdoors, it is still a good test to perform to determine the quality level of the metal that the factory is using, and how likely the product is to corrode should it accidently come in contact with water, etc. Some items on which you should definitely perform this test are: keychains, bicycle parts and outdoor furniture. Some items for which this test may be applied if you are looking for higher quality products include: electronic items, bag accessories and hardware (zippers), and indoor use toys.

What kind of products is applicable to Salt Spray (Corrosion) Testing
Tuesday, January 31st, 2012What is Salt Spray(corrosion) Testing
Monday, January 30th, 2012Salt Spray Testing, also known as corrosion testing, is a lab testing method that is used to determine if metal parts of the product will rust and/or corrode when exposed to water and inclement weather. This test is generally included in the lab testing protocol of any product which has exposed metal parts.
ISTA-Integrity Test Procedure
Sunday, January 29th, 2012The entire document shall be read and understood before proceeding with a test.
There are three sections: Overview, Testing and Report
Overview provides the general knowledge required before going into the testing laboratory and
Testing presents the specific instructions to do the testing in the laboratory and
Report indicates what data shall be recorded to submit a test report to ISTA.
ISTA Test Procedures and Test Projects are the worldwide leaders in Performance Tests for Packaged-Products. Two systems of weights and measures are presented in ISTA test procedures. They are the English system (Inch-Pound) and the international system SI (Metric). Inch-Pound units are shown first with Metric units in brackets, except in some tables where they are shown separately.
Either system may be used as the unit of measure (standard units), but The standard units chosen shall be used consistently throughout the procedure. Units are converted to two significant figures and Not exact equivalents.
Package Testing: ISTA Test Procedure 1A
Saturday, January 28th, 2012The test drop height varies with the weight of the packaged-product. Find the weight of the packaged-product in the following chart to determine a drop height or an equivalent impact velocity to be used for a substituted drop:
Packaged-Product Weight Drop Height Impact Velocity
Equal to or greater than But Less than Free Fall Incline or Horizontal
lb kg lb kg In. mm ft/s m/s
0 0 21 10 30 760 13 3.9
21 10 41 19 24 610 11 3.4
41 19 61 28 18 460 10 3.0
61 28 100 45 12 310 8.0 2.5
100 45 150 68 8 200 6.6 2.0
The test method requires the packaged-product to be dropped in several different package orientations.
A drop test must be performed in all required orientations where dropping the packaged-product is practical.
If dropping in a required orientation is not practical an equivalent incline or horizontal test can be substituted for that orientation.
When using impact velocity, if any test in a Test Sequence is below the required minimum level, that sequence event must be repeated until the test impact velocity meets the minimum.
Pcakage testing ISTA-Preshipment Testing
Friday, January 27th, 2012The ISTA Preshipment Test Procedures provide a means for a manufacturer to predetermine the probability of the safe arrival of their packaged products at their destination through the utilization of tests developed to simulate the shocks and stresses normally encountered during handling and transportation. ISTA has confined its technical activities to the packaged product only. Neither the product nor the container is considered separately. The tests, it is stressed, are basic tests. Test level and sequence should be changed to adapt to known distribution situations and these changes are documented in the report.
These test procedures are performance tests and, when properly applied, will provide tangible benefits of reduced damage, economically balanced costs, and improved customer satisfaction. It is also emphasized that these procedures are not intended to evaluate the protection afforded packaged products from other conditions such as moisture, corrosion, contaminating odors, etc. They may or may not comply with carrier requirements for packaging.
To maintain certified status and eligibility for identification with the TRANSIT TESTED seal, each packaged product must be retested whenever a change is made in either the product, the process, or the package. Changes in the packaged product include changes in design, size, and/or material. As a quality control procedure, packaged products should be retested as frequently as feasible.
Very Important
ISTA
Thursday, January 26th, 2012ISTA, the association for transport packaging, is an international leader in advancing the science of packaging and the use of performance testing techinques. Its member companies are supported in the development of effective packaging, methods, and logistic systems that prevent or reduce transportation and handling damage during product distribution. ISTA test procedures are continuously under review and updated periodically. To ensure that you are utilizing the most recent publication of the test procedure, contact ISTA at www.ista.org
