Abstract:
This document goes through the procedure for preparing an ETM/ITM penultimate mass (D080117 and D080128) for installation into the quadruple suspension structure. The procedure consists of hydroxide catalysis bonding on a fused silica ‘ear’ (suspension element according to D080751-v1) to each of the surfaces S3 and S4 in a well-defined location, gluing wire break-off prisms to the mass, gluing magnet flags to surface S2 of the mass and re-storing the mass.

Notes and Changes:
v12 Norna added note on checking date of bonding solution which should not be used if more than 1 year old.
v13 Norna has expanded statement at beginning of section 3 referring to the use of the document T1300322 for guidance on bonding sapphire prisms to PUMs.
