Several international and national standards govern ASTM D792 testing:

These standards outline the requirements for measuring specific gravity using the displacement method. Manufacturers must comply with these standards to ensure that their products meet the necessary safety, performance, and quality requirements.

Standard Development Organizations

The development of standards is a collaborative effort between standard development organizations (SDOs), industry experts, and regulatory bodies. The SDOs responsible for ASTM D792 include:

These SDOs work together to establish, maintain, and revise standards to ensure they remain relevant and effective.

Standard Evolution and Updates

Standards evolve and get updated regularly to reflect changes in technology, regulations, and industry practices. The standard development process involves several stages:

1. Identification of a need for a new or revised standard

2. Formation of a working group consisting of experts from various organizations

3. Development of the standard through a consensus-based approach

4. Review and approval by SDOs

5. Publication and implementation

Manufacturers must stay informed about updates to relevant standards to ensure compliance.
