UL 498 Figure 74.2 SB1888 Typical Test Apparatus

This UL 498 Figure 74.2 SB1888 Typical Test Apparatus is engineered to fully comply with the technical requirements specified in Figure 74.2 of the UL 498 standard (“Attachment Plugs and Receptacles”). This dedicated testing instrument is designed to evaluate blade retention performance of attachment plugs and receptacles—a critical safety parameter that ensures electrical blades maintain secure positioning during operation, preventing accidental disconnection or exposure to live components. The apparatus incorporates essential functional components to simulate operational conditions, enabling precise and repeatable testing. It serves as an essential tool for manufacturers, testing laboratories, and quality assurance departments to verify that plugs and receptacles meet the stringent safety and performance requirements established by UL 498.

Specifications:

• Full compliance with UL 498 standard, specifically aligned with the technical specifications of Figure 74.2 (“Typical test apparatus”)
• Spring scale component for measuring force required for blade retention testing, ensuring accurate force quantification
• Blade retention pin, a critical component that interfaces with sample blades to assess retention strength
• Simulated face plate designed to replicate actual installation environments of plugs and receptacles, ensuring test conditions accurately reflect operational scenarios
• Top view and front view structural configurations meeting dimensional and assembly specifications detailed in UL 498 Figure 74.2
• Engineered specifically for blade retention performance testing of attachment plugs and receptacles

Test Procedures:

• Prepare attachment plug or receptacle sample for testing, ensuring absence of visible damage, correct assembly according to product specifications, and compliance with UL 498 pre-test conditions
• Configure typical test apparatus on a stable, level testing platform. Verify all components (incl… (truncated)
