3.3.1 Vibration. Washer-extractors shall be designed to isolate and minimize vibration transmitted to the floor and
surrounding building structure during the extraction cycle. The amplitude of the vibration at the base of the washer-
extractor which is in contact with the floor shall not exceed 0.005 inch total indicator reading taken with a mass
vibrometer when the washer-extractor is operating in the extraction cycle at full rated load and maximum extraction
speed with a five percent load unbalance in one pocket of the cylinder. Vibration isolation design shall not require
unusual or special foundation construction materials. Anchor bolts shall be selected from readily available
materials, grades and sizes to handle anticipated dynamic loads.
3.3.2 Noise. Noise level shall not exceed 85 decibels (A scale), when measured at the operators position (in front of
and within 36 inches of the control panel).
3.3.3 Cylinder reversing. Cylinder revolutions in one direction shall not vary by more than five percent from
cylinder revolutions in the opposite direction between reversals
3.3.4 Pre-extract load distribution. Pre-extract load distribution shall be automatic and continue at distribution
speed until any unbalance situation is reduced to an acceptable level for high speed centrifuging of the wash load.
3.4 Order of precedence. in the event of a conflict between the text of this CID and the referenced documents cited
herein, the text of this CID shall take precedence. Nothing in this CID, however, shall supersede applicable laws
and regulations unless a specific exemption has been obtained.
3.5 Data. Each machine shall include a copy of the manufacturer's standard "owner/operator manual" applicable to
the machine. The manual shall include instructions for operating the machine, safety precautions, preventative and
routine maintenance instructions, and installation instructions which identify utility interface and machine
foundation details. This data shall be the same information that is normally provided with similar machines sold in
the commercial market.
3.6 Metric product. Products manufactured to metric (SI) dimensions shall be considered on an equal basis with
those manufactured using inch-pound units of measure, provided they fall within the specified tolerances using
conversion tables contained in the latest revision of ASTM E 380, Standard Practice for Use of the International
System of Units (SI), and all other requirements of this Commercial Item Description are met. If a product is
manufactured to metric dimensions and those dimensions exceed the tolerances specified in inch-pound units, a
request should be made to the contracting officer to determine if the product is acceptable.
4.1 Occupational Safety. Washer-extractors shall conform to Occupational Safety and Health Act (OSHA), 29 CFR
1910 (see 3.2.1 .4).
4.2. Recovered materials. The offeror/contractor is encouraged to use recovered materials in accordance with
Public Law 94-580 to the maximum practical extent. Recycled or reclaimed materials may be used in the
construction of the equipment described herein. Recycled and reclaimed materials shall consist of previously used
material which has been reprocessed to become a source of new raw materials. Under no conditions or
circumstances shall the contractor submit to the Government for acceptance reconditioned or rebuilt components as
a part of the equipment described herein.
