IIn a global market where safety standards are paramount, FOTUX—a cutting-edge brand under SANYUAN Group—leverages the group’s advanced R&D capabilities to deliver next-generation fire-retardant and fire-resistant cable solutions.

In 2025, FOTUX enhanced its testing infrastructure with the latest cable fire performance apparatus, establishing a top-tier, state-of-the-art Cable Fire Performance Test Laboratory. This facility enables FOTUX to conduct rigorous, comprehensive assessments of cable fire safety, ensuring superior protection and reliability.

Comprehensive Fire Safety Testing Capabilities

Test for vertical flame propagation (single insulated wire or cable)

This test evaluates the burning behavior of single cable (600mm sample) in a fire.
By verifying whether the flame can extinguish itself and the length of the burn damage, it can be judged whether the cable meets the CPR Eca level.

Standards:

  • IEC 60332-1-2
  • EN 60332-1-2
  • UL 1581 FT1&VW-1

Test for vertical flame spread
(bunched wires or cables)

This test method tests a cable bundle (3600mm) with regard to fire propagation.
According to the flame spread after applying specified flame power and burning time to the cable bundle, the cable can be classified into Category A, B, C, and D.

Standards:

  • IEC 60332-3-22 up to 25 Cat A-D
  • EN 60332-3-22 up to 25 Cat. A-D

Test for heat release and smoke production during flame spread
(bunched wires or cables)

This advanced test not only measures flame spread but also assesses the burning behavior and smoke production of bunched cable.
Fire growth rate and heat release are the main basis for cable CPR Dca to B1ca classification, while smoke generation and flaming droplets are used for additional classifications of s and d.

Standards:

  • EN 50399 CPR Dca-B1ca

Test of circuit integrity (FE/PH)

This test is used to determine whether a single cable can maintain circuit integrity during a specific fire exposure period.
Depending on market standards and specific application requirements, mechanical shock or water spray may also be applied during the cable burning process. Cables that meet the test requirements are marked with ‘FE180,’ ‘PH120,’ or other relevant standard compliance marks following their model numbers.

Test of circuit integrity (fire only)

  • IEC 60331-11/-21/-23/-25
    (>750 °C)
  • BS 6387 (Category C)
    (950 °C)

Test of circuit integrity (fire and mechanical shock)

  • IEC 60331-1/-2
    (>830 °C, 2A)
  • EN 50200 (PH)
    (>830 °C, 2A)
  • BS 6387 (Category Z)
    (950 °C, 3A)

Test of circuit integrity (fire and water)

  • EN 50200 Annex E
    (>830 °C, 2A)
  • BS 6387 (Category W)
    (650 °C, 3A)
