Instrument Manufacturing for Measuring and Testing Electricity and Electrical Signals
NAICS 334515 · United States · 2022 edition
This U.S. industry comprises establishments primarily engaged in manufacturing instruments for measuring and testing the characteristics of electricity and electrical signals. Examples of products made by these establishments are circuit and continuity testers, voltmeters, ohm meters, wattmeters, multimeters, and semiconductor test equipment.
Start the review with products liability.
For Instrument Manufacturing for Measuring and Testing Electricity and Electrical Signals, the saved research highlights products liability, commercial property, employee injuries. Confirm how these arise in the actual operation, what controls are used and whether additional services change the proposed coverage.
Questions to ask
- What types of instruments are manufactured, and in what industries or applications are they primarily used?
- Is there any distribution to safety-critical sectors such as utilities, aerospace, medical, or defense?
- What is the geographic scope of product distribution — domestic only, or international?
- Are there quality-control and calibration documentation processes in place?
- Any prior product liability claims, recalls, or customer disputes over instrument accuracy?
- Are prototype or demonstration units regularly shipped to trade shows or customer sites?
- For Instrument Manufacturing for Measuring and Testing Electricity and Electrical Signals, what should the underwriter know about instruments used in nuclear, aerospace, defense, or medical-diagnostic applications where measurement errors could cause serious harm?
- For Instrument Manufacturing for Measuring and Testing Electricity and Electrical Signals, what should the underwriter know about significant prior products liability losses or product recall history?
