What are the industry standards for Coaxial Cable Assemblies

Coaxial cable assemblies are indispensable in industries like telecommunications, aerospace, automotive, and medical equipment. Their ability to transmit high-frequency signals with minimal interference directly determines the performance of end systems. To ensure consistency, safety, and interoperability across products worldwide, a set of rigorous industry standards has been established. These standards govern every stage from design and material selection to manufacturing and testing, providing clear guidelines for both producers and buyers.

1. Core International Standards

1.1 IEC (International Electrotechnical Commission) Standards

The IEC 61196 series is the most widely recognized global standard for coaxial cables and assemblies, covering both general and specific requirements:

IEC 61196-1: Defines general specifications, including terminology, dimensional tolerances for cables (e.g., conductor diameter, insulation thickness), and basic electrical performance benchmarks (e.g., characteristic impedance ranges of 50Ω, 75Ω, and 93Ω for different applications).
IEC 61196-2: Focuses on mechanical test methods, such as static and dynamic bending tests (e.g., static bending radius shall not be less than 10 times the cable outer diameter; dynamic bending radius not less than 15 times), tensile strength tests, and connector mating durability (requiring at least 500 insertions/extractions without performance degradation).
IEC 61196-3: Specifies electrical test protocols, including impedance measurement (using a network analyzer to ensure deviation within ±5%), voltage standing wave ratio (VSWR, maximum 1.5 at operating frequency), and attenuation (e.g., for a 50Ω cable at 2GHz, attenuation shall not exceed 0.8dB/m).

This series is applicable to commercial and industrial coaxial assemblies, such as those used in broadband routers and industrial control systems.

1.2 ANSI/ICEA (American National Standards Institute/Insulated Cable Engineers Association) Standards

ANSI/ICEA standards are widely adopted in North America, with a strong focus on telecommunications and cable TV (CATV) applications:

ANSI/ICEA S-96-489: Targets coaxial assemblies for CATV and broadband networks. It emphasizes low signal loss (e.g., attenuation at 1GHz for 75Ω cables ≤0.5dB/m) and electromagnetic interference (EMI) shielding effectiveness (requiring braided shields with ≥95% coverage or foil-braid combinations to block external interference).
ANSI/ICEA S-95-658: Applies to industrial coaxial assemblies, adding requirements for resistance to oil, chemicals, and harsh indoor/outdoor environments (e.g., resistance to UV radiation for outdoor use).

1.3 MIL-STD (U.S. Military Standards)

MIL-STD standards are designed for high-reliability scenarios like military and aerospace, where performance under extreme conditions is critical:

MIL-STD-1553: Governs coaxial assemblies used in aerospace data buses (e.g., aircraft avionics). It mandates extreme temperature resistance (-55℃ to +125℃), vibration resistance (10-2000Hz, 10g acceleration), and shock resistance (50g for 11ms).
MIL-DTL-17: Specifies material and manufacturing requirements for coaxial cables in military assemblies, such as using silver-plated copper conductors for low resistance and Teflon insulation for high-temperature stability. Testing includes salt spray (5% NaCl solution for 48 hours) and humidity cycling (95% RH at 40℃ for 10 days) to ensure durability.

2. Key Dimensions Covered by Standards

All major standards uniformly regulate three core aspects of coaxial cable assemblies:

Electrical Performance: Ensures signal integrity, including consistent impedance, low attenuation, minimal crosstalk between adjacent cables, and high EMI shielding.
Mechanical Durability: Guarantees resistance to physical stress, such as bending, pulling, and connector wear, to avoid signal loss from structural damage.
Environmental Adaptability: Tailors requirements to usage scenarios, such as high/low temperatures, humidity, chemicals, and radiation (for aerospace), to prevent performance degradation in harsh conditions.

3. Industry-Specific Special Standards

Beyond general standards, niche sectors have additional requirements:

Medical Industry: ISO 10993 (biocompatibility, ensuring no toxic materials) and IEC 60601 (electrical safety, preventing electric shock in medical devices like MRI machines).
Automotive Industry: ISO 11801-6 (resistance to engine oil, high temperatures up to +150℃, and continuous vibration for in-vehicle infotainment systems).
Aerospace: EN 3475-701 (European standard complementing MIL-STD, focusing on lightweight materials and resistance to high-altitude radiation).

Adhering to these standards is not just a compliance requirement—it is a prerequisite for ensuring the reliability of end systems. Whether for a home internet router or a military aircraft, choosing coaxial assemblies that meet relevant standards reduces operational risks and extends product lifespan.
