Location: Article 10,Mandatory Appendix lX,IX-1071.5 and lX-1080
Subject: Upstream Pressure Compensation and Leakage Rate Acceptance Criteria
Explanation: Paragraph lX-1071.5 has been revised to provide a more specific trigger for calculation of upstreampressure compensation.This revision eliminates previously used broad terms such as “nominal” and “substantiallyless”The revision also makes the requirement applicable when the acceptable leakage rate is stated with an upstreampressureother than 1atm absolute.In the 2019Edition,the requirementassumed thathe acceptable helium leakage rateis stated with a 1 atm absolute upstream pressure, which meant it did not address cases where the upstream pressure issomething other than the typical 1 atm absolute. Paragraph lX-1080 has been revised to clarify that leakage rate accep-tance criteria may be from a Code Section,the productspecification,or the product design, and to identify the correlationbetween the acceptable leakage rate, the specified upstream pressure, and the specified helium concentration.
