Purpose
- Establish a standardized process for collecting information on chemicals contained in mixtures, materials, products / articles and technologies. This enables compliance with regulatory and customer requirements, while preventing business interruption and improving supply chain transparency.
Benefits
- Maintain a declarable substances list that aerospace and defense sector can use voluntarily — to ensure suppliers and manufacturers have a single, authoritative reference so declarations are consistent and comparable.
- Support PFAS risk mitigation by improving understanding and guidance — consolidating the currently available PFAS listed in national inventories.
- Supply a declaration form to streamline supply chain requests — reduce administrative burden and increase response quality by providing standardized form tailored to common product and material scenarios.
- Promote Standards that solution providers and PLM tools can incorporate to drive consistent declaration data exchange at system-to-system level interaction.
- Provide worked examples of declaration calculations for industry use — offer step-by-step examples, so organizations can calculate and report accurately and consistently.
Objectives
- Standardization: Establishing and promoting industry standards that enhance safety, efficiency, and interoperability across aerospace systems and processes.
- Knowledge Sharing: Creating a platform for members to share insights, experiences, and technical expertise, fostering a culture of continuous learning and improvement.
- Collaboration: Encouraging partnerships among stakeholders to drive innovation and address complex engineering challenges that require a multidisciplinary approach.
