As a key component for transmitting signals and currents between rotating and stationary parts, the quality of slip rings is directly related to the stability, safety, and service life of equipment, thus making the quality certification system particularly important. Currently, the slip ring industry generally adheres to multiple authoritative international and domestic standards, verifying product quality through multi-dimensional testing.
In terms of international certifications, ISO 9001 Quality Management System Certification is a basic requirement, ensuring that the entire process of slip rings, from design, raw material procurement to manufacturing and finished product inspection, is under strict quality control.
Electrical performance certification is a core assessment indicator of slip ring quality, including insulation resistance testing (ensuring insulation between rotating and stationary parts, usually requiring ≥1000MΩ@500VDC), withstand voltage testing (no breakdown or arcing under 1.5-2 times the rated voltage), contact resistance testing (requiring stability and minimal resistance to avoid signal transmission loss), and anti-interference performance testing (such as Electromagnetic Compatibility (EMC) certification, ensuring normal operation in complex electromagnetic environments).
Mechanical performance certification is also indispensable, covering rotational speed testing (verifying operational stability at rated speed and short-term overspeed conditions), life testing (evaluating wear and performance degradation through millions of rotation cycles), vibration and shock testing (simulating mechanical environments during transportation and operation, in line with standards such as IEC 60068), and temperature range testing (usually required to operate within a wide temperature range of -40℃ to +85℃, with special models capable of reaching higher or lower temperatures).
In addition, for special needs of different industries, slip rings must obtain special certifications.
