Stowage shall not adversely affect carrying stability of the equipment and shall be contained in a manner that prevents damage to the equipment during transit.

2.3 Environmental Requirements. The PVBS shall meet the environmental requirements as specified in 2.3.1.

2.3.1 Temperature and Humidity. The PVBS shall meet the conditions below:

2.4 Marking and Identification. The PVBS shall be in accordance with paragraphs 2.4.1 and 2.4.4 below.

2.4.1 ID Plate. The PVBS transit case shall have a metal ID plate (placard) specifying the instrument model number, serial number, nomenclature, manufacturer, and FSCM/CAGE number. The serial number shall match the serial numbers of the phase bridges provided.

2.4.2 ID Card. The PVBS transit case shall have an ID card on the inside of the case lid. The ID card shall have a picture of all of the items contained in the PVBS transit case. The ID card shall have the model number of the PVBS at the top of the card and each item within the case will be identified by model number (or part number if no model number is available) and nomenclature. Serial numbers shall not be included.

2.4.3 Calibration Label. The contractor shall affix a calibration label to each PVBS transit case specifying the serial number, date that the instrument was calibrated, calibration interval (next date due), and manufacturer or lab performing the calibration. The government reserves the right to extend the calibration interval (next date due) without any impact or consequence to the manufacturer.

2.4.4 Warranty Label. The contractor shall affix a warranty label to each PVBS transit case specifying instrument model number, serial number, nomenclature, manufacturer, FSCM/CAGE number, contract number, and warranty expiration date.

2.5 Performance. Performance requirements for the PVBS shall be in accordance with the sub-paragraphs below. These requirements comprise the full performance requirement for the PVBS. All performance specifications shall apply with a laboratory temperature of 15 to 30°C and a relative humidity of 20 to 60%. Where applicable (e.g. two-sided) specifications should be stated with a coverage factor k=2 producing an interval having a level of confidence of approximately 95%.

2.5.1 1:1 Resistive Phase Bridge. The PVBS 1:1 resistive phase bridge shall have a nominal loading of 50 kΩ at inputs 1 and 2 at bridge balance. The phase error at balance shall be within 1 m° to a frequency of 1 kHz, and 2 m° with a frequency range of 1 kHz to 50 kHz.

2.5.2 1:1 Capacitive Phase Bridge. The PVBS 1:1 capacitive phase bridge shall have a nominal loading of 900 pF at inputs 1 and 2 at bridge balance. The phase error at balance shall be within 2 m° with a frequency range of 1 kHz to 50 kHz, and 8 m° with a frequency range of 50 kHz to 200 kHz.

2.5.3 10:1 Capacitive Phase Bridge. The PVBS 10:1 capacitive phase bridge shall have a nominal loading of 900 pF at input 1 and 90 pF at input 2 at bridge balance. The phase error at balance shall be within 2 m° with a frequency range of 5 kHz to 50 kHz, and 8 m° with a frequency range of 50 kHz to 200 kHz.
