Proof Test Levels for Advanced LIGO Viewports

Document #:

LIGO-E1101226-v4

Document type:

E - Engineering documents

Abstract:

Inert environment, proof testing is required for all brittle, non-metallic materials on the vacuum envelope. This document defines the proof test levels for all of the Advanced LIGO viewports.
