Product Overview
The ZLT-BS1 Flame Propagation Tester is a professional solution for evaluating the vertical flame propagation resistance of single vertical electrical insulated conductors, cables, and optical fibre cables. Developed in line with IEC60332-1 and IEC60332-1-2 standards, this tester features a 1KW nominal pre-mixed flame (per IEC60695-11-2) to replicate harsh fire scenarios. As a trusted manufacturer, we offer the ZLT-BS1 with an MOQ of 1 unit, payment via T/T, shipping from Guangzhou Port, and a lead time of 20 days. It is widely used in cable manufacturing, electrical safety testing, and regulatory compliance to ensure cables meet global fire safety requirements.


Product Features
Standardized Flame Source
The 1KW pre-mixed flame (per IEC60695-11-2) delivers consistent heat output, ensuring test results are comparable across labs. The burner’s design (matching IEC60695-11-2 Figure A) guarantees uniform flame shape and intensity.
Precise Temperature Monitoring
The Type K thermocouple (0.5mm O/D) offers a wide temperature range (200℃~1050℃) and 1℃ resolution, enabling real-time tracking of flame temperature. This precision helps identify subtle changes in cable flame resistance.
Robust Test Chamber
The internal 300mm×450mm×1200mm chamber provides ample space for vertical cable samples, while the 45° burner angle (fixed) ensures flame interacts with the cable in a standardized way—critical for repeatable results.
Versatile Compatibility
The tester works with single insulated conductors, power cables, and optical fibre cables, making it suitable for multiple industries (e.g., electronics, telecommunications, automotive).
Application
The ZLT-BS1 is essential for organizations involved in cable safety and compliance, including:
Cable Manufacturers: Testing finished products (e.g., PVC-insulated cables, optical fibre cables) to ensure they meet IEC60332-1 requirements before market launch.
Electrical Equipment Makers: Verifying the flame resistance of cables used in appliances (e.g., refrigerators, air conditioners) to prevent fire hazards.
Telecommunications Industry: Testing optical fibre cables to ensure they resist flame propagation in data centers or outdoor installations.
Testing Labs: Conducting third-party audits for clients in aerospace, marine, and industrial sectors, where cable fire safety is critical.
FAQ
What gas is required for the ZLT-BS1, and is it included?
A1: The tester requires propane with a minimum 95% purity, but gas is not provided (to comply with shipping safety regulations). Customers can source propane locally from certified suppliers.
Can the ZLT-BS1 test optical fibre cables?
A2: Yes. The tester is designed for single vertical electrical insulated conductors, cables, and optical fibre cables—as specified in IEC60332-1 and IEC60332-1-2.
What is the purpose of the standard copper block?
A3: The 10±0.05g Cu-ETP copper block is used to calibrate the flame temperature (per IEC60695-11-2), ensuring the 1KW flame meets standard heat output requirements before testing.
Q4: Is the power supply compatible with 110V 60Hz regions (e.g., North America)?
A4: Yes. The standard power supply is 220V 50Hz 3A, but we offer an optional 115V 60Hz configuration for regions with different electrical systems. Please confirm your needs when ordering.
