German PTL glow wire test apparatus the T03.35 use operating procedures A glow Wire Tester

Glow wire tester (T 03.35) CB Products
　　 1 Overview
Electrical components or parts failure or overload conditions, may reach a high temperature or light around them parts, the thermal stress caused by the simulation component of the PTL is the hot wire test or overload resistance, heat or ignition sources in a short time Method for Evaluating fire danger.
　　 PTL glow-wire test is IEC6 0695-2-10: 2000 ~ IEC60695-2-13: 2000 "glow wire / hotline, the basic test methods, the glow wire test apparatus and common test procedures and UL746A, DIN695 IEC829, VDE0471 and other standard requirements use of non-flame ignition source simulation project.
　　 PTL Glow wire tester will provide for the material and shape of the heating of the heating wire with a large current to the test temperature (550 ° C to 960 ° C) for 1 min to the required pressure (1.0N) vertical the burnings test product 30s, depending on the test product and bedding matter whether the ignition or holders of the fuel to determine the fire hazard of electrical and electronic equipment finished; determination of the ignitability of solid electrical insulating materials and other solid combustible materials, ignition temperature (GWIT), flammability and the flammability index (GWFI).

PTL glow wire test apparatus for lighting, low voltage electrical appliances, household appliances, machine tools, electrical appliances, motors, power tools, electronic equipment, electrical instruments, IT equipment, electrical business equipment, electrical fittings and accessories such as electric and electronic products and its The component parts of the research, production and quality control departments, but also applies to insulating materials, engineering plastics, or other solid combustible materials industry.
　　
　　 (2) Equipment Overview:
(1) Model: T03.35
　　
　　 Three instrument configuration and technical specifications:
(1) nickel - chromium hot wire diameter of 4mm, the ring made ??of a standard size.
(2) measuring the temperature of the hot wire with a nominal diameter of 0.5mm armor mounted filaments thermocouple NiCr-Nia, ￠ 0.5mm, 100mm long. .
(3) thermocouple placed in the top of the glow wire drilled holes, and to ensure good thermal contact, the thermoelectric power meet ZBY300 requirements.
(4) The test device is designed so that the hot wire kept in a horizontal plane, 1N weights hung on the inside of the chassis is not easy being outside corrosion changes the weight. Its sample exert 1N of force, and the glow wire test sample relative movement in the horizontal direction has been to maintain this pressure value in the process of at least 7mm distance.
(5) Open the sample holder.
(6) flame gauge adjustable.
(7) temperature display instrument display range (0 to 1000) ° C, 0.5 rating, with the glow wire temperature adjustment.
(8) pulse timer, automatic test timing control, automatic control sample testing time and retreat samples.
(9) motor drive, automatic control sample frame forward and backward.
(10) hot wire current display table, range (0 ~ 160), grade 1.0, built-in operation with the current regulation.
(11) security keys, the key is not turned on is not operational.
(12) testing process automatic control from the operator factors affect the outcome. .
(13) to adjust the hot depth of 7mm.
Burning on the kind of imposed time (Ta) (14) the range of 0 to 99 minutes, 99 seconds, adjustable in general accordance with the standard requirements is automatically set to 30 seconds
(15) the speed of movement of the test sample: 10mm / s, ~ 20mm / s,; are generally raised to 16 mm / s,.
(16) CB laboratory specified
