PCA: ASTM International releases new product category rules for several cements

ASTM International has released the final product category rules (PCR) for Portland, blended hydraulic, masonry, mortar and plastic stucco cements.

The PCA notes that the development of PCR for the cement industry elevates the visibility and adoption of cement's sustainable benefits. "Product category rules are the basis for environmental product declarations (EPDs), which provide quantified environmental data using predetermined parameters," the association states.

EPDs allow purchasers and users to make informed comparisons between building materials when using life cycle analysis on construction projects, the PCA adds. EPDs rely upon the detailed instructions for data collection and life cycle assessment calculations found within the PCR.

"I commend our member cement companies for collaborating on a standardised method for discussing information about the environmental impact of several cement products," says Cary Cohrs, PCA Board of directors chairman. "Through this process, we are able to truly understand the impact of cement on the environment."

According to ASTM: "In order to create a comparable EPD, they must follow the same rules," said Christopher Surak, director of certification programs at ASTM International. "PCRs, similar to standards, are developed in a collaborative manner and ASTM is uniquely positioned to provide the venue for developing an industry PCR."
