DCR:
310
Number:
310
Name:

E-mail:

Organisation:
DLR
Changes required for:
N/A
Status:
Implemented
Date status:
2006-12-19
Signature:
Ralf de Marino
Document attachments:
Assembly_procedure_for_an_attenuator.pdf
Modifications:
Accordingly the DCR should be amended to read as follows:
Para 1.5 Maximum Ratings
Add the following text to Note 3:
"During engagement of the component with its mating counterparts the body of the component shall be restrained by means of the body flats whilst torque is applied to the coupling nuts (see Para 1.6)"
Para 1.6 Physical Dimensions
Add a "Notes" column to the table with new Note 1 against Dimension 'D' as follows:
"The body flats shall be used to restrain the body during engagement whilst torque is applied to the coupling nuts"
--------------------------------------------------------------------------------
Justification:
As Max ratings already includes the Coupling Nut Torque rating (information to be applied by users during application) this is considered to be the best location in the spec for the new engagement note. The above proposed alternate wording is considered clear & sufficent. There is no need to add a new para 1.8 nor to add a new figure as per the original DCR.
