SAFETY RELATED PARTS. We have expanded our Q. A. Program to meet a broader spectrum of your safety related needs. Besides our ASME Sect. III (NCA-4000) program, we can supply non-Code, safety related parts to the requirements of 10CFR50, Appendix B. In all cases, Fisher nuclear industry parts are provided to the requirements of 10CFR21.

COMMERCIAL GRADE DEDICATION. Fisher supplies a broad range of products as "Commercial Grade Dedicated" under our 10CFR50, Appendix B, Q. A. Program, which are provided to the requirements of 10CFR21. This provides the ability to dedicate certain instruments and actuator accessories, such as Regulators, Boosters, Transducers, Positioners, and Filters.

NUCLEAR SERVICE INSTRUMENTS.
Fisher Controls Nuclear Service Instruments incorporate the use of EPDM (or EPT) elastomers, including o-rings, gaskets, and EPDM/Nomex TM diaphragms. To meet your 10CFR21 requirements, these are "commercial grade dedicated" under our 10CFR50, Appendix B, Q.A. program. These instruments include the Type 3582NS Positioner, Type 2625NS Booster, and the Type 546NS I/P Transducer (qualified to IEEE 323 and 344).

NUCLEAR SERVICE DIAPHRAGMS. The EPDM/Nomex TM Diaphragm design incorporates the advantage of EPDM elastomers and Nomex TM fabric in forming a very effective diaphragm system, resulting in increased temperature and radiation resistance and longer shelf life. Fisher's Safety Related Diaphragms provide nitrile/nylon diaphragms, as well as EPDM/Nomex TM diaphragms, to the requirements of 10CFR50, Appendix B, and 10CFR21. These are available with elastomer batch and fabric lot numbers molded on the back for full material traceability.
