The boundary of the internal sound barrier must extend under the edge of

13、the periphery seal. Type IV requirements for sound barrier material Mass 4.88 kg/m2 minimum Specific Gravity 1.2 2.8 Tensile Strength 1350 kPa minimum Tear Strength 4500 N/m minimum Elongation 45% minimum Shore A Hardness 85 +/- 10 4.1.4 Thickness The cab insulator shall have a nominal thickness of

14、2.5 cm (1 in) except for designated areas on the drawing where the thickness is reduced to afford higher strength or clearance. (Thickness of some part families may vary depending upon die plate requirements.) 4.1.5 Density The cab insulator will have a nominal per part weight of 114-228 grams/foot2

15、 (3-6 lbs/ft3) of cured fiberglass (mineral wool), with a tolerance of -20% + 25% of the nominal weight. 4.2 Thermal Insulation Efficiency 4.2.1 Method: ASTM C 177 4.2.2 Requirement Shall be 0.033 watt/meter deg K (0.23 BTU in/hr ft deg. F) at 24C (75F) min. 4.3 Coating (Types I, II, III, IV, V) 4.3

16、.1 Material The engine side surface shall be coated with an oil resistant elastomeric compound (chloroprene or a modified nitrile) providing protection from the environment and thermal and acoustical protection. The standard coating shall be filled with aluminum to enhance radiant heat performance.

17、A black coating is available though not recommended. The coating weight varies by sound transmission loss requirements: NUMBER: MPAPS L-6609 TITLE: Molded Fiberglass, Cab Insulator REVISION: 1702 This document is restricted and may not be sent outside Navistar, Inc. or reproduced without permission
