Simpson Gumpertz & Heger’s (SGH) (Waltham, Massachusetts, USA) Applied Science & Research Center recently received ISO/IEC 17025 accreditation from the American Association for Laboratory Accreditation (A2LA) (Frederick, Maryland, USA) for several concrete testing methods. Conducted at SGH headquarters, these procedures weren’t through a stringent process with A2LA professionals observing and auditing the facility in 2022 and will be reaudited biannually.

According to SGH, achieving this accreditation (Certificate Number: 6551.01) affirms the company’s commitment to quality and allows them to continuing enhancing the services they provide to clients and peers across the industry.

“I am impressed every day at the breadth and depth of our testing capabilities,” says Norman Perkins, SGH director of Applied Science & Research. “Our technical professionals and laboratory staff continue to grow their expertise in physical testing, environmental simulations, materials science, microscopy, and research partnerships, and allow us to serve our clients through all phases of a project.”

The ISO/IEC 17025 accreditation focuses on quality requirements specific to laboratory testing and ensures that recipients have the correct policies, procedures, equipment, and training in place. The recognized testing methods focus primarily on concrete:

  • ASTM C39 – Compressive Strength of Cylindrical Concrete Specimens 
  • ASTM C42 – Obtaining and Testing Drilled Cores and Sawed Beams of Concrete 
  • ASTM C138 – Density, Yield, and Air Content of Concrete 
  • ASTM C143 – Slump of Hydraulic Cement Concrete 
  • ASTM C192 – Making and Curing Concrete Test Specimens in the Laboratory 
  • ASTM C231 – Air Content of Freshly Mixed Concrete by the Pressure Method 
  • ASTM C566 – Total Evaporable Moisture Content of Aggregates by Drying 
  • ASTM C469 – Static Modulus of Elasticity and Poisson’s Ratio of Concrete in Compression 
  • ASTM C1064 – Temperature of Freshly Mixed Hydraulic Cement Concrete

“Our laboratory, its staff, and all our engineers are constantly finding ways to push the boundaries of our testing capabilities,” says Niklas Vigener, SGH chief technology officer. “This accreditation is another example of how we are able to partner with our clients and peers in the AEC [Architecture, Engineering, and Construction] industry and beyond.”

SGH’s 13,500 square foot, in-house laboratory facilities allow the company to develop and execute comprehensive testing and research plans to better understand how materials, components, and systems behave. Their technical professionals partner with team members in the center to identify project goals, develop testing protocols, interpret results, and advance client solutions.
