Final answer:
Among the provided codes AB-506, AB-513, AB-526, and AB-535, the correct code for the Inspection & Servicing Requirements for In-Service Pressure Equipment is AB-506.
Step-by-step explanation:
The Administrator in the pressure equipment discipline has established that ABSA document AB-506 "Inspection & Servicing Requirements for In-Service Pressure Equipment" outlines the integrity assessment and pressure relief valve servicing requirements that must be met for in-service pressure equipment, as provided for under Sections 39 and 41 of the Pressure Equipment Safety Regulation (PESR). However, AB-506 does not provide detailed coverage of repairs and changes. Document AB-513 Pressure Equipment Repair and Alteration Requirements contains the requirements for post-construction repairs and modifications.
