PDA Standards Development

Why Have Standards?

Standards serve a very important purpose and are a part of our daily lives − in the lab where our samples are tested, in the equipment that we use at the gym, to the way we work and perform our jobs. We need them to help keep us safe, to make sure that there is consistency in how products are made, tested, and used by all, and sometimes the government may mandate compliance with a standard in lieu of government guidance. Standards benefit everyone too—industry, government, consumers, young professionals, and students.

ANSI logoPDA is recognized by industry professionals and regulators around the world who rely on PDA’s peer-reviewed technical documents for expert guidance and opinions on important scientific and regulatory topics. Therefore, the logical and natural progression was for PDA to expand this expertise into the world of creating standards that provide guidance to the industry on best practices for drug manufacturing for patient use.


The PDA became a Standards Developing/Development Organization (SDO) through the American National Standards Institute or ANSI for short. ANSI is a private, non-profit 501(c)(3) organization whose mission is “to enhance both the global competitiveness of U.S. business and the U.S. quality of life by promoting and facilitating voluntary consensus standards and conformity assessment systems and safeguarding their integrity.” ANSI does make it easier to come to an agreement by accrediting the procedures used by standards developers, and by making sure that these procedures allow for openness, balance, consensus, and due process. These principles mean: anyone who wants to contribute can, no one group can monopolize or skew procedures in its favor, and, should someone feel that he or she wasn’t given proper consideration, procedures are in place to review and evaluate the situation to ensure the process was conducted fairly and equally.

Becoming an accredited Standards Developer means that the process and steps performed by PDA meet the guidelines set forth by the American National Standards Institute (ANSI) in the ANSI Essential Requirements: Due Process Requirements for American National Standards ( The key elements include openness, consensus vote, due process, lack of dominance, balance, public review/consideration of views and objections, an appeals process, and compliance with the ANS policies and administrative procedures.

The PDA Standards Development Process


How is ANSI related to ISO?

ANSI is the sole U.S. representative of ISO, and a founding member; hence, ANSI plays an active role in ISO governance. ANSI has also been a strong and active leader in ISO’s sister organization, the International Electrotechnical Commission (IEC), as well as other international and regional standardization bodies. By being accredited through ANSI, PDA has the opportunity to also participate in ISO standards development.

Want to Be a Part of Standards Development Process and Know More?

Membership in any PDA standards development activity is open to everyone, particularly those that may be interested or involved in production, application, and regulation of products related to the pharmaceutical, biopharmaceutical, scientific, and regulatory community.
