Safety boundary. DraftVerify does not set universal dispense pressures, gas blends, cylinder rules, regulator service intervals, or pressure-vessel requirements. Those values and procedures shall come from the beverage producer, equipment manufacturer, qualified technician, and applicable law or code.

1. Purpose

F-26 ensures that gas-system configuration does not undermine the identity, traceability, or verified configuration of an in-scope NA draft pathway.

2. Qualified configuration

Gas type, blend, operating pressure, regulator configuration, check-valve requirements, and component suitability shall be determined by competent personnel using applicable external requirements.

DraftVerify certification shall not be represented as certification of pressure-system engineering or gas safety.

3. Identification

Where gas configuration is material to correct operation of an in-scope NA product, the organization shall maintain sufficient identification to determine:

• applicable gas source;
• product or line served;
• relevant regulator or control point; and
• current approved configuration.

4. Change control

A material gas-system change affecting an in-scope pathway shall be controlled under F-27 and documented before the affected NA pathway is returned to verified service.

5. Unsafe or uncertain condition

If personnel identify a suspected leak, damaged pressure component, unknown gas source, unknown regulator setting, or other potentially unsafe condition:

• service shall be stopped where required by the applicable safety procedure;
• the condition shall be escalated to qualified personnel; and
• DraftVerify verification shall not be used as authority to perform technical repair.

6. Records

Where required by the certification scope, service records shall identify:

• date;
• affected system or line;
• person or service organization;
• material configuration change; and
• re-verification status.

7. Certification effect

A gas-related condition is a DraftVerify nonconformity when it:

• makes the intended NA pathway uncertain;
• causes registry or physical configuration to disagree;
• prevents required verification; or
• remains unresolved after a material system change.

A separate safety hazard may also require action under external law or qualified technical procedures independent of DraftVerify.
