Curtis-Straus LLC History

Curtis-Straus’ roots date back to 1979, during the genesis of the EMC revolution. Isidor Straus founded one of the first FCC-accredited test sites in the country (DS&G) and hired a bright young MIT student, Jon Curtis, who would become the lab’s chief engineer.

The steady market demand for EMC regulation testing exploded with the introduction of the EU EMC Directive. To respond to that need, in 1997 a new venture was formed with a mission to build a boutique lab driven by “technical expertise, operational excellence with a superior customer experience.” Equipped with no more than a white party tent, a rented HP spectrum analyzer, and a set of Roberts antennas, Curtis-Straus was born. By 1999, an 18,000 square foot facility in Littleton, Massachusetts was operating four fiberglass all-season “Open Area Test Sites” (OATS), two anechoic RF chambers, and a full complement of immunity testing equipment.

By 2001, Curtis-Straus had become a Nationally Recognized Testing Laboratory (NRTL), accredited by the Standards Council of Canada (SCC), and became one of the few Verizon-accredited “Independent Test Labs” (ITL) in the country.

As the world grew smaller and domestic manufacturers started to think more globally, Curtis-Straus needed bigger and broader regulatory compliance testing solutions to meet their client’s needs. In 2005, Curtis-Straus was acquired by Bureau Veritas, one of the largest and most well-respected players in the global certification market.  Overnight, Curtis-Straus was able to provide local clients with global market access product safety testing services.
