MATERIAL TECHNICAL DATA IMPACT RESISTANS/MECHANICEL ABUSE All parts (flat surfaces, corners, etc.) of the enclosures were subject to impact and abuse tests as specified in U.L. Standard 508. DIELECTRIC STRENGTH 467 Volts/mill per ASTM D648. FLAMMABILITY Self extinguishing (ASTM D635) HIGH CURRENT ARC IGNITION Tests terminated after 2000 arcs failed to produce ignition. HEAT DEFLECTION Fiberglas enclosures tested ASTM D648. No deflection measured at temperature up to 392°F at which point test was terminated. FUME TOXITY Fumes emitted during burning to destruction are non-toxic in nature, except for some nominal emission of carbon monoxide, which is common with all organic materials. TEMPERATURES RESISTANCE Fiberglass materials are suitable for use in environments of from –58°F to 320°F. Momentary temperatures of 392° will not be harmful. WATER ABSORPTION (2 x 2 x 5/32 coupons) Fiberglass – 45 mg in 4 days VOLUME RESISTIVITY Fiberglass lateral tested for volume resistivity to ASTN D257 After 40 hours at 73.4°F, 50% relative humidity – 1 x 1015 ohm cms. COLOR Fiberglass is colored a pleasing neutral grey. The color is molded-in and is homogeneous. throughout the material. Enclousures may be painted with high grade polyurethane or epoxy paints after suitable surface preparation. Specific details furnished upon request. STABILITY DIN53388-7 (best figure by this method is 8). Useful outdoor life for polyester materials exceeds 25 years. Erosion is less than 3% of thickness over 30 years and does not effect mechanical strength. UV protected throughout the material. WORKING QUALITIES Enclosures may be modified by drilling, sawing, hole punch, etc. The pre-impregnated hot molding process renders after-treatment of worked areas completely unnecessary. TROPICAL DUTY Suitable for use in tropical service. Tropical environment tests, to IEC68-2, were performed without damage to enclosures, also resisting mold, fungus growth, etc. VERMIN; TERMITES; ETC: Enclosures will resist attack by rodents, vermin, termites, etc. |
