LANL MASTER SPECIFICATION

This template must be edited for each project.  In doing so, specifier
must add job-specific requirements.  Brackets are used in the text to
indicate designer choices or locations where text must be supplied by
the designer.  Once the choice is made or text supplied, remove the
brackets.  The specifications must also be edited to delete
specification requirements for processes, items, or designs that are not
included in the project \-- and specifier's notes such as these.  To
seek a variance from requirements in the specifications that are
applicable, contact the Engineering Standards Manual Mechanical
[POC](http://engstandards.lanl.gov/engrman/6mech/htmls/mechnew2.htm).
Please contact POC with suggestions for improvement as well.\
\
When assembling a specification package, include applicable
specifications from all Divisions, especially Division 1, General
requirements.\
\
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.

3.  Packaging and shipping

    A.  Package and ship ASME AG-1, Section FC HEPA filters per the
        requirements for level B items in accordance with ASME NQA-1
        and:

        1.  Place filter cartons on an oversized pallet and secured or
            crated to eliminate unit handling at carrier inter change
            points and avoid unnecessary damage.

        2.  Do not stack HEPA filters more than three high.

        3.  For large shipments, ship the entire shipment in a sealed
            dedicated trailer or rail car to provide an additional
            quality assurance of product shipping and handling.

            to stack filters more than three high, if the individual
            filter does not exceed 24 inches in size, but the stacked
            height can not exceed 6 ½ feet.

        2.  Ship filters properly orientated, in accordance with

ASME AG-1, Section FC regulated filters are designed specifically for
use in nuclear facilities. For Auxiliary HEPA, consider filter
environment when selecting acceptable materials. Example: PTFE may not
be an acceptable material for a radiation environment. Also note, the
listing of materials for Auxiliary HEPA filters is not a complete list
of possible materials, others may be acceptable. Again, carefully
consider the environment (corrosion, radiation, etc) in which the filter
will be operating.

    1.  Examination

        A.  Inspect all filters upon shipment receipt and before
            installation for visual damage such as cracks, tears in
            filter media or dents in housing. Inspect gaskets for
            cracking or other signs of degradation. Verify documentation
            from Section 1.6 is included and is complete.

    and :

    1.  Do not stack HEPA filters more than three high.

    2.  Store filters properly orientated, as indicated on shipping
        container.

    3.  Do not store filters for more than 10 years after manufacture
        date. If filter has been in storage for greater than 3 years,
        visually inspect gaskets for cracks, before installation.

B.  Store auxiliary HEPA filters in accordance with the manufacturer's
    requirements and:

    1.  Do not stack filters more than three high. It is acceptable to
        stack filters more than 3 high if the individual filter does not
        exceed 24 in. in size, but the stacked height can not exceed 6 ½
        feet.

    2.  Store filters properly orientated, in accordance with
        manufacturer's recommendations.

    3.  Do not store filters for more than 10 years after manufacture
        date. If filter has been in storage for more than 3 years,
        visually inspect filter unit, especially seals for damage before
        installation.
