1.标准体系与适用范围 Standard system and scope of application
UL1424：美国保险商实验室（UL）制定的标准，主要针对北美市场，适用于建筑布线、通信设备等场景，强调单根电缆的阻燃性能（如UL1581-VW-1）和电气特性。利路通取得UL1424标准电缆认证。
UL1424: A standard developed by Underwriters Laboratories (UL) primarily for the North American market, applicable to scenarios such as building wiring and communication equipment, emphasizing the flame retardant performance (such as UL1581-VW-1) and electrical characteristics of individual cables. Lilutong has obtained UL1424 standard cable certification.
BS7269：英国标准协会（BS）发布的标准，属于IEC体系，更注重成束电缆的燃烧性能（如IEC60332-3）和耐火特性，常见于欧洲及英联邦国家的建筑、工业领域。
BS7269: A standard published by the British Standards Institution (BS), belonging to the IEC system, which focuses more on the combustion performance (such as IEC60332-3) and fire resistance characteristics of bundled cables. It is commonly used in the construction and industrial fields in Europe and Commonwealth countries.
2.性能要求差异 阻燃测试：Performance requirement difference flame retardant test:
UL1424通常要求通过单根垂直燃烧测试。
UL1424 typically requires passing a single vertical combustion test.
BS7269则侧重成束燃烧测试（如IEC60332-3），评估电缆在密集敷设时的火焰蔓延控制能力。
BS7269 focuses on bundle combustion testing (such as IEC60332-3) to evaluate the flame spread control capability of cables during dense laying.
耐火性能：Fire resistance performance:
BS7269可能包含线路完整性测试（如EN50399），要求电缆在火灾中持续运行；而UL1424更关注阻燃性。
BS7269 may include line integrity testing (such as EN50399), which requires cables to operate continuously in the event of a fire; UL1424 places greater emphasis on flame retardancy .
3. 典型应用场景 Typical application scenarios
UL1424：适用于数据中心、商业建筑等需符合北美规范的场景，如六类非屏蔽双绞线（遵循ANSI/TIA-568标准）。
UL1424: Suitable for scenarios such as data centers and commercial buildings that require compliance with North American standards, such as Category 6 unshielded twisted pair cables (following ANSI/TIA-568 standard).
BS7269：多用于医院、地铁等对耐火要求高的公共设施，如多芯防火报警线，利路通取得多国认证，如国德国TUV认证、英国LCPB认证。
BS7269:It is commonly used in public facilities such as hospitals and subways that require high fire resistance, such as multi-core fire alarm lines. Lelutong has obtained certifications from multiple countries, such as TUV certification in Germany and LCPB certification in the UK.
4. 材料与结构Materials and Structure
UL1424：常用PVC或HDPE护套，导体为无氧铜（OFC），注重电气性能（如特性阻抗100±15Ω）。
UL1424: Commonly used PVC or HDPE sheath, conductor made of oxygen free copper (OFC), emphasizing electrical performance (such as characteristic impedance of 100 ± 15 Ω).
narios.
BS7269：可能采用矿物绝缘（如BS638）或低烟无卤材料，强调机械强度与耐环境性。
BS7269: Mineral insulation (such as BS638) or low smoke halogen-free materials may be used, emphasizing mechanical strength and environmental resistance.
综上，两者选择需根据目标市场法规和具体需求：北美项目优先UL1424，欧洲或耐火场景则倾向BS7269。
Overall, the choice between the two should be based on the target market regulations and specific needs: UL1424 is preferred for North American projects, while BS7269 is preferred for European or fire-resistant scenarios。
