Concrete Company Receives Accreditation

Concrete testing in SGH’s Applied Science & Research Center

Waltham,MA – Simpson Gumpertz & Heger’s (SGH) Applied Science & Research Center recently received ISO/IEC17025 accreditation from the American Association for Laboratory Accreditation (A2LA) for several concrete testing methods.

These procedures, conducted in SGH’s Waltham headquarters, went through a stringent evaluation process with A2LA professionals observing and auditing the facility in 2022 and will be re-audited biannually.

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
