Frequently Asked Questions about Lamp Cap Gauges
Go gauges verify that the lamp cap dimensions do not exceed the maximum allowable tolerances (the cap must fit into the gauge). Not Go gauges check that the dimensions are not smaller than the minimum required tolerances (the cap must not fit). Both types are mandatory under IEC 60061-3 to ensure full dimensional compliance, interchangeability, and electrical safety of lamps and lampholders.
All our lamp cap gauges are manufactured strictly according to IEC 60061-3 (7006 series). We also provide gauges compliant with GB/T 1406, EN 60061-3, ANSI/UL 496, and CSA standards, making them suitable for global market access including Europe, North America, and Asia.
For high-frequency use in production or laboratory environments, we recommend calibration every 6 months. For occasional use, once per year is usually sufficient. KingPo can supply detailed calibration procedures and offer ISO 17025 traceable calibration services.
Yes. Many of our gauges are regularly used by certification bodies and manufacturers for UL 496, IEC 60598, and EN 62560 compliance testing. They help verify critical safety parameters such as contact protection, torque resistance, and dimensional interchangeability.
Our gauges are precision-machined from high-grade hardened tool steel (HRC 58-62). This material provides excellent wear resistance, dimensional stability, and long service life, ensuring measurement accuracy remains within tight tolerances even after thousands of inspection cycles.
Yes. We offer full gauge sets for popular lamp caps including E27, E14, E26, E40, B22, and GU10. Each set typically includes Go, Not Go, and special purpose gauges, along with technical drawings and calibration certificates.
To maintain accuracy, gauges should be lightly oiled, stored in a dry, dust-free environment, and protected from impacts. Regular visual inspection for wear is recommended before each critical testing session.
Absolutely. We frequently produce custom gauges based on customer drawings, modified IEC standards, or proprietary specifications. Please provide the required standard number, dimensions, or sample, and our engineering team will deliver within 15-25 working days.
