The coils shall be 13.5 gauge steel and the helicals shall be 17 gauge steel. The size of the indi

12、vidual parts will be indicated by the engineering drawing. When indicated on the engineering drawing, the innerspring will articulate to fit into the sleeper compartment. Type II: The innerspring configuration shall be a 5” Holland Maid Innerspring unit 308 count (based on full size). The interior c

13、oils shall be 13.5 gauge steel, edge coils shall be 13 gauge steel and the helicals shall be 17.5 gauge steel. Type III: The innerspring configuration shall be a Marshall Unit, 520 count (based on full size). The coils shall be electronically tempered, 15.5 gauge steel, 5-1/8“ Samson technology and

14、will be individually encased by ultrasonically welding special Hanes Quantum non-woven fabric that flexes with the coil. The innerspring unit shall taper from top to bottom to accommodate a smaller bottom width and length of finished mattress. The mattress ticking shall be constructed of a bamboo st

15、retch knit material per TMS-7088, Type IV. 4.1.2 Border Rod Type I: Border rods shall be made of 9 gauge steel wire. Type II: Border rods shall be made of 6 gauge steel wire with three Holland Wire edge clips evenly spaced and affixed to the top and bottom border wire on each side of the length on t

16、he innerspring. Type III: Border rods shall be 9 gauge steel wire affixed with c-rings. 4.1.3 Insulator Type I: The insulator shall be .75 oz. resinated fiber pad, top and bottom. Type II: The insulator shall be .75 oz. resinated fiber pad, top and bottom. Type III: The innersprings are individually

17、 wrapped in cloth; therefore, an insulator is not required. 4.1.4 Padding Padding materials shall be sufficient to meet the finished size requirements as well as the performance requirements. 4.1.5 Foam Foam for innerspring mattresses shall meet the requirements of TMS-6505 with the following ILD re
