The premix would be delivered in a tanker truck twice a year. The chemical and physical properties of the DBS shall meet the requirements of Military Specification DOD-B-82669(OS). Item Property Description Minimum Maximum a Color (Pt-Co Scale) --- 10 b Acidity (as Acetic Acid), wt.% --- 0.05 c Saponification number 350 360 d Refractive index, nD25 EC 1.4385 1.4405 e Moisture, wt.% --- 0.15 f Sodium, ppm --- 1.0 The DBS shall not contain any foreign material including, but not limited to bits of Teflon, dirt from the floor, metal shavings or trash from the trash can. The chemical and physical properties of the 2-NDPA shall meet the requirements of Military Specification in accordance with MIL-N-3399. Item Property Description Minimum Maximum a Solidification point, - C 73.0 --- b Purity, wt.% 97.5 --- c Volatile matter, wt.% --- 0.6 d Material insoluble in 95 % ethyl alcohol, wt.% --- 0.2 e Ash, wt.% --- 0.1 f pH Value 5.0 7.0 g Acidity (as HC1), wt.% --- 0.003 The 2-NDPA shall not contain any foreign material including, but not limited to bits of Teflon, dirt from the floor, metal shavings or trash from the trash can. PREMIX CHEMICAL AND PHYSICAL SPECIFICATION The chemical and physical properties of the formulated Premix containing DBS and 2-NDPA shall be analyzed as described below and conform to the requirements in the table below: Item Property Description Minimum Nominal Maximum a Di-N-butyl Sebacate, wt.% --- 93.65 --- b Residual moisture, wt.% --- --- 0.10 c 2-Nitrodiphenylamine, wt.% 6.20 6.30 6.40 d Impurities, wt.% (measured by Gas Chromatograph analysis) --- --- 0.60 (1) DBS weight percent shall be based on difference. (2) Residual moisture weight percent shall be analyzed using a Karl Fisher moisture analyzer. (3) 2-NDPA weight percent shall be analyzed using a spectroscopic instrument. For example the Thermo Scientific Spectronic 200E has been used successfully in the past to measure 2-NDPA content. The 2-NDPA standard shall be made from the same 2-NDPA lot used in the Premix lot. (4) Overall impurities in premix shall be measured by gas chromatograph curve. Peaks that are not 2-NDPA or DBS are measured as impurities. (5) Record DBS and 2-NDPA addition weights using a certified scale. (6) Additionally the DBS and 2-NDPA material lots used in the premix manufacture shall meet the chemical and physical properties in sections 2.1 and 2.2, respectively. The premix shall not contain any foreign material including, but not limited to bits of Teflon, dirt from the floor, metal shavings or trash from the trash can. The premix shall be filtered using a 1 micron filter element that is compatible with the chemicals in the premix. Please provide MSDS for DBS and 2-NDPA Premix. All interested sources shall provide a company brochure or list of specifications, organization name, address, a point of contact, phone number, fax number, e-mail address, business size, taxpayer identification number, DUNS number, and CAGE Code.
