[LANL MASTER SPECIFICATION]{.underline}

When editing to suit project, author shall add job‑specific requirements
and delete only those portions that in no way apply to the activity
(e.g., a component that does not apply). To seek a variance from
applicable requirements, contact the ESM Mechanical POC.

When assembling a specification package, include applicable
specifications from all Divisions, especially Division 1, General
Requirements.

Information within "stars" is provided as guidance to the author
responsible for revising the specification. Delete information within
"stars" during editing.

This specification serves as a template. The specification was prepared
by an organization operating under a quality assurance program that
meets the requirements of 10 CFR 830 (suitable for ML-1 through ML-4
projects). Implementation of this specification requires modification to
the specification to meet project‑specific requirements. Responsibility
for application of this specification to meet project‑specific
requirements lies with the organization modifying or implementing the
specification. The organization modifying the specification shall apply
a graded approach to quality assurance based on the management level
designation of the project. When this specification is used with nuclear
facilities subject to 10 CFR 830, modification to this specification
must be performed by an individual or organization operating under a
quality assurance program that meets the requirements of that CFR.

This specification serves as a template for procurement of filters at
LANL. There is a list of filters that are pre‑approved for use in LANL.
The performance and design requirements for these filters can be found
and referenced in Part 4 (attachments). If none of the pre‑approved
filters meet the performance or design requirements for a particular
application, use this specification in its template format to procure a
different filter.
