“FR” Tubing(Flame Retardant)
Developed specifically for controllingflame spread and smoke generation,Dekoron 1219 FR (flame retardant)Tubingcan be installed in accordance withNFPA. Standard 90A “Installation of AirConditioning and Ventilation Systems1985.”
Dekoron 1219 FR Tubing is made of anexclusive “linear” low-density polyethy-lene based formulation that is UL recog-nized. It combines the physical character-istics and long-term stability of low densitypolyethylene with flame retardant proper-ties. Look for UL Classification marking onproduct.
ArwantagesDekoron 1219 FR Tubing prevents firepropagation, as it rapidly extinguishesafter being removed from an open flame.“FlYTubing is very similar to Dekoron“P” Tubing for flexibility, lightweight,abrasion resistance. high tensile strengthand rugged environmental performance.TO guarantee stress crack resistance,both the standard ASTM D ,693 test forstress cracking of base materials and amodified test on finished tubing areperformed.

Color Designations ForStriped “FR” Tubing
Note: In addition to the standard stress crack test,a modified version of ASTM D 1693 to evaluatetubing quality is also performed. Sections oftubing are bent to induce severe stress in thetubing wall and then submerged in a 10% sol”-tion of lgepal (CO630). The samples and solutionare placed in a controlled temperature environ-ment at 50°C. Samples must exhibit no crackingor crarlng throughout the duration of the test to
___j be considered satisfactory for extended “se.
