The Core of Fire Safety: Maintaining Circuit Integrity

Unlike standard cables that only focus on flame retardancy, fire-resistant cables are designed to keep critical systems—such as fire alarms, emergency lighting, and smoke extraction fans—operational even when exposed to direct flames. The Baoruitong tester is specifically engineered to verify this “Circuit Integrity,” providing manufacturers and laboratories with the data needed to certify high-performance cables.

Key Technical Features and Selling Points

Baoruitong’s testing systems are built to deliver laboratory-grade accuracy through a combination of robust hardware and intelligent software:

1. Integrated Testing Capability: Our systems can be configured to perform multiple evaluations in a single setup, including fire resistance, mechanical impact (simulating falling structural debris), and water spray resistance, meeting the requirements of comprehensive standards like BS 6387 and EN 50200.
2. Stable Flame Conditions: Utilizing high-precision mass flow controllers (MFC) and standardized burners, the equipment ensures a consistent and repeatable thermal environment (750∘C750∘C to 950∘C950∘C), eliminating variables that could affect the accuracy of the test results.
3. Smart Control & Data Storage: The integrated PLC control system features a user-friendly touch-screen interface. It allows for automated timing, real-time monitoring of electrical loads, and secure data storage, ensuring full traceability for third-party audits and quality control records.
4. Durable Stainless Steel Construction: The combustion chamber is fabricated from high-grade stainless steel to withstand thousands of high-temperature cycles while remaining easy to clean and maintain.

Compliance with Global Standards

To help manufacturers access international markets, the Baoruitong Cable Tester ensures strict compliance with the industry’s most recognized protocols:

• IEC 60331 Series: The global benchmark for testing the circuit integrity of cables under fire conditions.
• BS 6387 (Categories C, W, Z): Evaluating resistance to fire, water, and mechanical shock.
• EN 50200 & BS 8491: Standards for small and large-diameter fire-resistant cables.

FAQ

Q1: What is “Circuit Integrity” in fire testing?

A: Circuit integrity refers to the ability of a cable to continue conducting electricity or transmitting signals without short-circuiting or failing while being exposed to a specified fire source for a set duration (e.g., 90 or 180 minutes).

Q2: Does the equipment support mechanical impact and water spray tests?

A: Yes. Depending on the model, Baoruitong systems can be equipped with an automated mechanical hammer for impact testing and a specialized spray nozzle to simulate fire-fighting water exposure, as required by BS 6387.

Q3: How is a “Failure” detected during the test?

A: The apparatus includes an integrated monitoring system that connects to the cable’s conductors. If a short circuit occurs or a fuse blows due to material degradation, the system immediately records the “Time to Failure” and alerts the operator.

Q4: Can the burner position be adjusted for different cable diameters?

A: Absolutely. Our testers feature adjustable mounting systems that allow for precise positioning of the burner relative to the cable sample, ensuring uniform heat application regardless of the cable size.

Q5: Is data export available for generating test reports?

A: Yes. All test data, including temperature curves and circuit status, can be exported via USB or Ethernet in standardized formats, facilitating easy report generation for certification and research purposes.
