Global Chemical Regulations and Materials of Concern
Pratt & Whitney continues to take
a leadership role in
the development of environmentally responsible
products, services and
Pratt & Whitney introduced the
Green Engine Program in the
1990’s to focus our Design for the Environment efforts, with the
goal to minimize the use of
Materials of Concern (MOC) in
Pratt & Whitney engine designs.
This effort resulted in our latest
family of engines being in the
forefront of Green Engine
technology in the aerospace
Materials of Concern
It is the policy of Pratt & Whitney
to eliminate or reduce the use of MOC in the design, manufacture,
maintenance, repair, overhaul,
operation and disposal of our
products. The Pratt & Whitney
MOC lists identify materials that
are prohibited or restricted for use in Pratt & Whitney products.
The lists provide substance
classifications in accordance with
specification PWA 328 and CPW 625 for use
during the product design
approval process. Material or
process substance use
declarations are also based on
the MOC lists, as applicable.
To meet customer and regulatory
compliance requirements, Pratt
& Whitney depends on suppliers
to submit and update Material
Declarations on request, and
to respond to material
declaration requests for existing
designs using the Material
Declaration form above.
Pratt & Whitney’s declaration form is updated periodically to meet business needs, and additional forms may be developed for different types of suppliers. It is Pratt & Whitney’s intent to request the minimum level of information required to meet business needs.
Reach Regulatory Compliance
Safe Use Communication
Article 33 in the REACH regulation requires that safe use information be communicated for Substances of Very High Concern (SVHC) when an article contains an SVHC in a concentration above 0.1 percent weight by weight (w/w). International Aerospace Environmental Group (IAEG) has developed user information for determining SVHC weight calculations. To date, Pratt & Whitney has identified the following SVHCs at greater than 0.1 percent w/w in articles:
To evaluate business continuity and compliance risk in our supply chain, Pratt & Whitney performs assessments of certain aspects of REACH at select suppliers. The assessment questionnaire is updated periodically to align with supply chain risk.
The REACH regulations require an Authorisation for continued use of Annex XIV Authorisation List substances in the European Economic Area and the UK after their assigned sunset dates. Because certain substances do not currently have suitable alternatives for use in all aerospace applications, Pratt & Whitney has worked with several industry consortia to obtain Authorisation to sustain supply chain business continuity. However, all members of our supply chain remain responsible for understanding and taking action on their obligations under REACH.
