Plastic flammability tester

2024-06-03 17:16

  Product Introduction

  The method described in UL 94 standard involves the standard size of the sample and the measurement and description of the flammability of materials used in equipment and electrical appliances, as well as the reaction to heat and combustion under laboratory controlled conditions. The actual response of materials to heat and combustion depends on their size and form, as well as the ultimate use of the material product. Other important features of evaluating the ultimate use of materials include but are not limited to: ease of ignition, combustion rate, flame spread, contribution of fuel, combustion intensity, and combustion products.

  The plastic flammability tester is designed according to the standard UL 94 and is used to measure the combustion performance of plastics and plastic components, in order to determine the fire resistance level of plastics.

  Product application

  This tester can be used to perform the following flammability tests

  (1) 94HB (ASTM D 635, ISO 1210): Horizontal testing

  (2) 94 V-0 V-1-V-2 (ASTM D 3801): Vertical testing

  (3) 94 5VA -5VB (ASTM D 5048, ISO 9772): 125 mm flame

  (4) VTM-0-1-2 (ASTM D 4804, ISO 9773): Vertical testing of non rigid materials

  (5) HBF - HF 1-2 (ASTM D 4986): Horizontal testing of foam polymer materials

  Instrument accessories

  (1) Timing system for combustion applications, post combustion, and start-up

  (2) The thermocouple connected to the thermometer measures the combustion temperature

  (3) Combustion chamber, according to ASTM D 5025 standard

  (4) Two thermocouples with copper blocks (5mm/9mm)

  (5) Soft sample holder

  (6) A bracket with joints and clips.

  (7) 20 mesh stainless steel wire mesh, approximately 125mm?.
