The JTETEST JN-SLZR-UL94 Horizontal Vertical Flame Chamber is designed for the flammability testing of plastic materials used in consumer electric devices and appliances. The chamber is constructed of stainless steel with a black interior and large sliding window for easy viewing. The JN-SLZR-UL94 includes a fully adjustable specimen support and a precision metered gas burner. Three digital timers with remote control are mounted on the inside back wall of the chamber, allowing for precise and simplified operation.
(I)Reference Test Specifications include:
Conforms to all UL 94 bunsen burner tests. Meets all five UL 94 horizontal and vertical Bunsen burner test specifications: UL 94HB; 4V-0,1,2; 94-5VA,B; 94VTM-0,1,2;
(II)Meets international testing standards: UL 94, ASTM D 635, 3801, 4804, 4986, 5048; ISO 9772.3, 9773; IEC 60707 and IEC 60695 –2004 Part 3-4 and 10-20 (replaces ISO 1210) (replaces ISO 10351) 、GB/T 5169-15-17 and 20-2008
IEC 707 (partial), ISO 9772 and ISO 9773
(II) Control system：
A、intelligent touch-screen and PLC are main control，testing time、testing times、burn-extending time are set and recorded on the touch-screen. Digital timers with resolution of 0.1 sec . In order to make the testing result more accurate，simple pilot model menu operation、direct-viewing！
B、Remote control with push button reset for in-chamber event timing,reduce testing error; except the special test.
C、match temperature measurement system，can control and adjust the needed temperature accurately.
1）thermo sensor（copper pipe and thermocouple）— the pipe should be extreme conductive electroanalysis copper；the flame of 1.76g pipe is 20mm，the flame of 10g pipe is 125mm.
2）K type thermocouple，match stainless steel tube that diameter of 0.5mm as sheaths.
3）Intelligent temperature control meter and K type thermocouple well matched ; the reading can up to more than 800℃.
（III）、Test device and test clamp：
