Who We Are

GD4 Test Services, Inc. (“GD4”) is an independent, privately owned electronic components third-party test lab with three U.S. locations: Austin, Texas (our corporate HQ and original test lab,) Largo, Florida; and Yaphank (Long Island,) New York.  We are a small business with a global reach.  

GD4 is neither owned by nor affiliated with any other manufacturer, broker, distributor, entity, person or silent partner.  In addition, GD4 does not buy, sell or is otherwise involved in the transaction of any components. This allows us to remain truly impartial when it comes to providing you with unbiased results and reports.

While many less-equipped test labs claim to be “compliant” to certain standards, ALL of GD4’s test facilities are fully certified ISO 17025, AS6171, AS6081, ISO 9001, AS9100 and ANSI / ESD S20.20.   GD4 is also DLA Lab Suitability and QTSL certified.

Our test labs are equipped to accommodate a wide variety of testing capabilities, counterfeit mitigation, device types and packaging variations. 

Our NAICS Codes are: 334419 (Other Electronic Component Manufacturing) and 541380 (Testing Laboratories.

We possess a number of hardware and software solutions which are already set up and ready for device testing. 

This efficiency significantly reduces the non-recurring engineering (NRE) fees and allows us to offer you quick and efficient turn times.  

We hear from and accommodate all industry types; from engineers to buyers, major manufacturing companies to distributors, and from brokers to end users.

GD4 is here to assist with all of your component testing and service needs.
