Summary of ASTM D5112 Vibration Laboratory Testing
ASTM D5112 regulatory compliance covers the determination of resonances of unpackaged products and components by means of horizontal linear motion applied at the surface.
Two alternative test methods are presented.
Test method A – Resonance Search Using Sinusoidal Vibration
Test method B – Resonance Search Using Random Vibration.
This information may be used to examine the response of products to vibration for product design purposes. It can also examine the design of a container or interior that will minimize transportation vibration inputs at the critical frequencies.
These product resonances must be within the expected transportation environment frequency range. Vibration damage is most likely to occur at product resonant frequencies and may be thought of as potential product fragility points.
Information obtained from the random vibration test method is used to assess the characteristics of the resonating components and product modification. This may become necessary if a product’s response would require the design of an impractical or excessively costly shipping container.
Scope of ASTM D5112 Horizontal Linear Motion Testing
The ASTM D5112 test does not necessarily simulate the vibration affects the product will encounter in operating or end-use environments. Other, more suitable test procedures should be used for this purpose.
Products are exposed to complex dynamic stresses in the transportation environment. The determination of the resonant frequencies of the product helps the designer in determining the proper packaging system. This helps provide adequate protection of the product. It also provides an understanding of the interactions between the components of the product.
Whenever sufficient products are available, five or more replicate samples should be tested. This will ultimately improve the statistical reliability of the data obtained.
ASTM D5112 Regulatory Integrity Test Procedures
Before testing, condition the test specimen and maintain them in accordance with any specific requirements applicable to the item being tested. In the absence of applicable requirements, condition the unit according to ASTM D4332. Perform the ASTM D5112 tests in the conditioned environment or immediately upon removal from that environment. Take caution to avoid mounting methods that cause excessive stress or strain that could alter the response of the product.
First, attach the specimen to the test surface in order to prevent it from moving across the test surface during the vibration. Next, test intensities are to be sufficient to vibrate the product at acceleration and frequency levels that determine the product resonance. Typical products show resonant frequencies ranging from 1.0 to 100 Hz.
Record any resonant responses of the product. Repeat the cycle if necessary
The report and ASTM D5112 test method cover general information such as date, time, location, and test engineer. Details of the package include the type of material and other characteristics. The number of packages tested and the number of failures is also included within the report, as well as any conditioning.
Specific details encompass the description of the test specimen, descriptions of any deviations from the specified test method, and a statement of whether the sine testing, random testing, or both were performed.
