STATEMENT OF WORK

STABINGER VISCOMETER(S)

9 June 2025

1. BACKGROUND

The Aerospace Fuels Laboratory at Vandenberg Space Force Base (AFPET/PTPLE) provides laboratory quality surveillance and investigative analytical support of flight critical products directly related to the warfighter and space launch operations on behalf of all Air Force and other Department of Defense (DoD) agencies, as well as commercial entities. AFPET/PTPLE has a vision to create a flexible, dynamic center of excellence that is responsive to customers and strategically positioned and focused on contingency and warfighter operations. We provide the warfighter and space launch activities specialized testing services and capabilities in petroleum, propellants, cryogenics, chemicals and gases for all aerospace vehicles, systems, and equipment.

2. SCOPE

AFPET/PTPLE has a requirement for two (2) Stabinger Viscometer Instruments with the ability to perform methods ASTM D7042 “Dynamic Viscosity and Density of Liquids by Stabinger Viscometer (and the Calculation of Kinematic Viscosity)” and ASTM D4052 “Density, Relative Density, and API Gravity of Liquids by Digital Density Meter” for routine aviation fuel, petroleum product and chemical specification and/or investigative testing.

On-site preventative maintenance services may be necessary to ensure core functionality, cleanliness, necessary adjusting, and accurate, repeatable performance.

Note: Copies of ASTM Methods may be obtained by writing to ASTM International, 100 Barr Harbor Drive, PO Box C700, West Conshohocken, PA 19428-2959; or by telephone at 610- 832-9255; or by e-mail at service@astm.org; or through the ASTM website at www.astm.org
