In the United States, the Occupational Safety and Health Administration (OSHA) and the Environmental Protection Agency (EPA) regulate the use of gypsum and lime products. Similarly, in Europe, the European Unions Construction Products Regulation (CPR) and the EU Emissions Trading System (EU ETS) influence the industry.

International and National Standards

The following standards are relevant to ASTM C1608:

  • ISO 9001:2015 - Quality management systems

  • EN 1749:2004 - Gypsum products - Determination of chemical composition

  • TSE 2340-2:2017 - Gypsum products - Specification for plasterboards and ceiling tiles

  • ASTM C471/C471M-19 - Chemical analysis of gypsum

    • Standard Development Organizations

    The development of standards is overseen by organizations such as the American Society for Testing and Materials (ASTM), the International Organization for Standardization (ISO), and the European Committee for Standardization (CEN). These organizations play a crucial role in updating and revising standards to reflect industry advancements and changing regulatory requirements.

    Standard Evolution and Update

    Standards evolve through continuous review, revision, and update. This process ensures that standards remain relevant, effective, and compliant with changing regulations. For instance, ASTM C1608 has undergone several revisions since its initial publication in 2005.

    Specific Standard Numbers and Scope

    The following standard numbers and scopes are relevant to ASTM C1608:

  • ASTM C1608-19: Chemical analysis of gypsum and lime - Scope: This standard provides a framework for evaluating the chemical composition of gypsum and lime products.
