Nothing in this document however, supersedes applicable laws and regulations unless a specific exemption has been obtained. 3. REQUIREMENTS 3.1 Mat

13、erials The strap leather shall be full grain or corrected grain cattlehide. Corrected grain leather shall be buffed or snuffed only to the extent necessary to remove superficial blemishes. 3.2 Tannage. The leather shall be vegetable tanned. 3.3 Physical requirements. 3.3.1 Trim (form and area). The

14、leather shall be furnished in the form of sides, backs, bends or double shoulders as required for the type specified. The area in terms of square feet shall be legibly marked in the butt area on the flesh side of the leather except that double shoulders shall be marked on the flesh side in the right

15、 hand corner formed by the straight edge cut and the belly cut. 3.3.2 Thickness. The thickness of the leather shall be as specified in the acquistion document (see 6.2). A tolerance of remove necessary amount of acetonitrile and inject Note: Samples may have to be diluted further to fall within stan

HPLC System with variable UV detector and integrating computer. Suitable syringe and glassware. b. A micro-Bondapak C18 column (Waters Associate

17、s P/N 2734) or equivalent. c. 0.45-micron polycarbonate filters (Nuclepore Corporation, Catalog No. 11 1107) or equivalent. d. Calculator capable of doing linear regression. e. Reagents: Acetonitrile (Chromatographic grade). 4.4.3.5.1 Typical mobile phase. Mix 550ml of distilled water and 450ml of a

18、cetonitrile. Filter and degas the solution. The concentration may be varied to meet system suitability requirements Within range 50% to 40 acetonitrile. 4.4.3.5.2 Typical chromatographic conditions: Injection Volume 20 Microliters Flow 2.5 dminute Detector 235 nm 4.4.3.6 System suitability. Inject t

19、he highest working standard until 2 percent agreement is reached between two successive injections. Chromatograph for approximately 15 minutes. Determine that, after the solvent front, one impurity peak elutes before the major peak. Elution for monoiodomethyl-para-tolylsulfone is about 6 minutes and

20、 for Diiodomethyl-para-tolylsulfone is about 8.5 minutes. 9 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-DTL-32068 4.4.3.7 Procedure. Inject each standard and sample preparation in duplicate allowing each injection to run for at least 15 minut

21、es. Measure the peak response for the Diiodomethyl-para- tolylsulfone. Note: The run time may have to be increased for samples with late eluting peaks. Perform a linear regression of peak response (area) versus concentration for each of the components. For each component: Concentration (ppm) in leat

22、her = Concentration (ppm) X75 from linear regression. Sample wt(g) 3.7 Cracking. The leather shall be tested for cracking in accordance with ASTM-D-6075. The diameters of the mandrels for the indicated thickness shall be as follows: Thickness of leather (ounces) Diametr of mandrel (inches) 2to5% 5%t

23、o9% 9 % and over 5. PACKAGING. 5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the contract or order (see 6.2). When actual packaging of materiel is to be performed by DoD personnel, these personnel need to contact the responsible packaging activity to as
