About Us

Company Description

Westpak is a 3rd-party, independent test laboratory specializing in product and package testing. Our facilities are certified by the International Safe Transit Association (ISTA) to perform transport-related tests. Most of the testing performed is accredited to ISO/IEC 17025 by the American Association of Laboratory Accreditation (A2LA) for various ASTM, ISTA, IEC and UL test protocols. We proudly became 100% employee-owned in 2017.

Mission Statement

Westpak's mission is to provide the best possible and highest-quality testing services in an environmentally friendly manner, using calibrated and well-maintained equipment at all times, conducted by test engineers and technicians who are knowledgeable, highly motivated, and well-trained.


Westpak has always believed that "Integrity is the Priceless Component in Testing". It’s clear to us, and probably to the rest of the world as well, that any test can be made to reinforce any bias if the test operator is slippery enough. We fully understand that clients come to Westpak for truthful answers to their questions, even if the results are not favorable or downright undesirable.

We believe that bad data is actually worse than no data. Without data, the typical designer is cautious. With bad data, that same designer is guaranteed to go the wrong direction.

We attempt to put ourselves in our clients' shoes and to provide the highest quality testing possible in the most efficient fashion.

Founding Principles

  1. Testing services should be delivered in the same fashion that we would want to receive them.
  2. Work should be an enjoyable and professionally fulfilling endeavor, not just a four-letter word.

Our Staff - San Jose and San Diego

All team members at Westpak participate directly in the operation of the company in some way. Within a short period of time after joining Westpak, all team members are thoroughly trained and expertly guided in a specific discipline. They are highly motivated and all understand the significance of offering outstanding customer service.

In a similar way, the management team understands the importance of providing the test engineers the best possible equipment, calibrated in the best manner, and maintained in a fully operational condition in a clean, comfortable environment. They are also focused on customer service and do everything in their power to maintain excellent customer relations.

Note from our Founder and Chairman, Herb Schueneman

Westpak CEO

As was stated above, Westpak was formed by two frustrated engineers who thought that testing services should be delivered in the same fashion that we would want to receive them. Imagine that? It was our method of applying the Golden Rule to a business enterprise. That same philosophy applies 30 years later and is an integral part of how we do business even today. In addition, I believe that work should be an enjoyable and professionally fulfilling endeavor, not just a four letter word. These are the keys to our success, our “secret sauce” if you will.

Westpak still practices these same two founding principles today and we are very happy about that. We believe our customers are some of the greatest people in the world and try our best to treat them that way. As a team, we work hard together, play hard together, and enjoy almost every moment of that experience. We are thankful every day for the blessings that we have received and for the professional advancements that we are able to achieve. As a Christian, I can find no better way to express this than a humble thank you to our clients, my esteemed, hardworking and wonderfully talented Westpak team members, and to our Maker.
