UL 2595 / CSA C22.2 NO. 0.23 STANDARD TRAINING GENERAL REQUIREMENT FOR BATTERY – POWERED APPLIANCES

INTRODUCTION FOR UL 2595 / CSA C22.2 NO. 0.23 STANDARD TRAINING GENERAL REQUIREMENT FOR BATTERY – POWERED APPLIANCES

Lithium-ion battery technology now dominates the cordless power tool battery market. As consumer demand increases, there is a growing need for lightweight, compact and longer-running batteries with larger energy density, lower discharge rates and faster charging that can maintain energy density over repeated recharging.

LEARNING OBJECTIVE

By the end of this training, participants will be able to:

1. Know UL 2595, the Standard for Safety for General Requirements for Battery-Powered Appliances
2. Understand IEC/UL 62841-1, the Standard for Safety for Electric Motor-Operated Hand-Held Tools, Transportable Tools and Lawn and Garden Machinery – Safety – Part 1: General Requirements
3. Apply IEC/UL 60335-2-29, the Standard for safety for household and similar electrical appliances – Safety – Part 2-29: Particular requirements for battery chargers
4. Know how to apply UN38.3, United Nations Manual of Tests and Standards for the Transport of Dangerous Goods

WHO SHOULD ATTEND

Engineers, Technicians, Supervisors, Designers, Project leads.

METHODOLOGY

Participants will be involved in:

Classroom lectures, Group discussions, Conduct gap analysis, Video shows, Pre and Post tests plus training evaluation measures the learning.
