requirements and square-foot weight.

1.05 [SYSTEM PERFORMANCE REQUIREMENTS]{.underline}

A. [Fire Performance Characteristics]{.underline}: Provide accordion
folding partitions with surface burning characteristics indicated below,
as determined by testing assembled materials composed of surface
coverings, backings, and other construction identical to those required
in this section, per ASTM E 84, by a testing organization acceptable to
authorities having jurisdiction.

1\. Flame Spread: 25 or less.

2\. Smoke Developed: 450 or less.

B. [Acoustical Performance]{.underline}: Provide accordion folding
partitions tested by independent testing laboratory acceptable to
authorities having jurisdiction, for the following acoustic properties,
according to the test method indicated:

1\. Sound Transmission Requirements: Accordion folding partition
assembly tested in a full-scale opening (14 feet by 9 feet) for
laboratory sound transmission loss performance in accordance with ASTM E
90, determined by ASTM E 413 and rated for a STC plus or minus 1 as
indicated:

a\. Sound Transmission Class (STC): 40.

1.06 [QUALITY ASSURANCE]{.underline}

A. [Single-Source Responsibility]{.underline}: Obtain accordion folding
partitions and mounting hardware from one source from a single
manufacturer.

B. [Testing Laboratory Qualifications]{.underline}: To qualify for
acceptance, an independent testing laboratory must demonstrate to Sandia
Delegated Representative (SDR)\'s satisfaction, based on evaluation of
laboratory-submitted criteria conforming to ASTM E 699, that it has the
experience and capability to conduct satisfactorily the testing
indicated.

C. All materials used shall not contain asbestos fibers or lead.

1.07 [DELIVERY, STORAGE, AND HANDLING]{.underline}

A. Deliver materials to project site in original factory wrappings and
containers, clearly labeled with identification of manufacturer, brand
name, quality or grade, fire performance characteristics, and lot
number.

B. Store only on edge, blocked off ground to prevent sagging and
warping, in original undamaged packages and containers, inside
well-ventilated area protected from weather, moisture, soiling, extreme
temperatures, and humidity.

C. Comply with instructions and recommendations of manufacturer for
special delivery, storage, and handling requirements.
