Probable Effect Concentration Quotients (PECQS) Practice Test

What is not a requirement for hard-service flexible cords?

1. Must be moisture resistant

2. Have low resistance to tugging

3. Ability to withstand high temperatures

4. Should have insulation for outdoor use

The correct answer is: Ability to withstand high temperatures

The ability to withstand high temperatures is not a requirement for hard-service flexible cords. These cords are primarily designed for use in applications that require flexibility and durability, rather than for extreme temperature conditions. Other factors, such as moisture resistance are crucial since cords are often used in environments where they may be exposed to moisture. Similarly, having low resistance to tugging is important to ensure that the cords can endure physical stress and movement without sustaining damage. Insulation for outdoor use further adds to the versatility of hard-service flexible cords, making them suitable for external environments. While some flexibility and durability may allow for certain high-temperature uses, it is not a defining requirement for all hard-service flexible cords. Thus, the correct answer highlights a characteristic that is not universally essential for them.
