This may be 2:1 v/v solution of butyl cellosolve acetate (diethylene glycol monobutyl ether acetate) and ethylene glycol. 15 minutes at 175 C. 3) Wipe tubing clean using Scotch Brite, dry, and reweigh. Zinc-rich paint coating must be sufficient to meet all perf

9、ormance requirements of this specification. 3.5 RESISTANCE PROPERTIES 3.5.1 Preparation of Specimens If not specified otherwise, prepare specimens as follows: Cut straight pieces of tube approx. 250 mm in length. Seal both ends, ie, dip both ends into suitable warm liquid wax (e.g. paraffin) having

10、a melting point above 55 C or use suitable end caps. Fasten the ends of 4 specimens parallel to an ABS-plastic or equivalent panel approximately 300 x 100 mm using tape (e.g. 3M #898) and leaving a space of about 10 mm between each specimen and backing sheet. 3.5.2 Adhesion No chipping or flaking Te

11、st Method: Scribe the tubing surface to obtain a 4.0 mm square crosshatch covering a minimum of 180 of circumference and 25 mm in length of tubing. Apply 3M #898 type tape to the scribed surface. Remove tape slowly, applying an even consistent tension. 3.5.3 Chip Resistance (FLTM BI 107-01) Prepare

12、10 specimens according to item 3.5.1 but fasten without space each specimen and backing sheet. The specimens shall be equal or better than the standard approved by the appropriate Product Engineering Materials Laboratory.
