ASTM D5112 Standard Test Method for Vibration (Horizontal Linear Motion) Test of Product

ASTM D5112 Vibration Testing

ASTM D5112 determines the resonances of unpackaged products by vertical linear motion. As an ISTA and ISO 17025 certified lab, we realize the importance of ASTM D5112 vibration testing. Meeting the ASTM D5112 requirements can be difficult. We understand the challenges and guide companies through the process.

Keystone Compliance partners with customers to achieve package compliance. We take a consultative approach throughout the entire test program. Our pricing is competitive and we offer volume discounts. Keystone provides the peace of mind that all of your needs will be met.

Summary of ASTM D5112 Horizontal Linear Motion Testing

The scope of ASTM D5112 integrity testing covers the determination by resonances of unpackaged products and components. This is done by means of horizontal linear motion applied at the surface on which the product is mounted. For vertical vibration testing of products see Test Method ASTM D3580.

This information may be used to examine the response of products to vibration for product design purposes, or for the design of a container or interior that will minimize transportation vibration inputs at the critical frequencies, when these product resonances are within the expected transportation environment frequency range.

Since vibration damage is most likely to occur at product resonant frequencies, these may be thought of as potential product fragility points.

Information obtained from the optional sinusoidal dwell and random test methods may be used to assess the fatigue characteristics of the resonating components and for product modification. This may become necessary if a product’s response would require design of an impractical or excessively costly shipping container.

Scope of ASTM D5112 Vibration Integrity Compliance

The ASTM D5112 test does not necessarily simulate vibration effects 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, either horizontal, vertical or both, aids the designer in determining the proper packaging system to provide adequate protection of the product. It also provides an understanding of the complex interactions between the components of the product as they relate to expected transportation vibration inputs.

ASTM D5112 transportation testing may produce sever mechanical response in the product being tested. Therefore, the means to fasten the product to the test surface needs to be of sufficient strength to keep it adequately secured. Operating personnel must remain alert to potential hazards and take necessary precautions for their safety.

ASTM D5112 Regulatory Transit Testing Procedures

The compliance test is performed in the conditioned environment or immediately after the unit under testing is removed from that environment. As mentioned above, the unit must be attached to the test surface so that it will prevent the specimen from leaving or moving across the test surface during vibration.

ASTM D5112 test intensities are conducted sufficiently enough to vibrate the product at specific acceleration and frequency levels. This determines if the product resonances exist in the expected frequency range. Typical products may exhibit resonant frequencies ranging from 1 to 100 Hz.

Test Method A: Sinusoidal Vibration – Select an acceleration is between 0.1 and 0.5 g. Sweep the frequency range from 1 to 100 Hz. Starting at 1 Hz, vary the frequency vibration at a continuous logarithmic rate of 0.5 to 1.0 octaves/min to 100 Hz and back to 1 Hz using either automatic or manual sweep. Maintain a nearly constant acceleration. Record any resonant responses of the product, repeating the cycle if necessary.

Test Method B: Random Vibration – This method is started such that the PSD levels do not overshoot the desired spectrum during startup. Operate at the full test level for a time duration long enough for the control system to stabilize. Furthermore, long enough for the data to be averaged sufficiently to represent stable spectrum, shapes and levels. Use a spectrum representative of the expected transportation environment or a flat broadband spectrum. Record any resonant responses of the product.

Expert ASTM D5112 Vibration Package Testing

In addition to ASTM D5112 vibration testing, Keystone has a full scope of expertise including cold chain, high impact shock, and leak penetration. Our team strives to give our customers more time and energy on product development instead of testing. Lastly, we can accommodate flexible and rigid packages of all sizes, including large pallets.
