UL 1659:1998 pdf download Attachment Plug Blades for Use in Cord Sets and Power-Supply Cords
1.11 These requirements cover the blades of attachment plugs and current taps intended to be connectedto the conductors of flexible cords using crimped connections, for use on cord sets and power-supply cordscomplying with the Standard for Cord Sets and Power-Supply Cords, UL 817, within the limits set forth in 1.2.1for type of blades and 1.3.1 for size of conductors
1.1.2 A product that contains features, characteristics, components, materials, or systems new or different fromthose covered by the requirements in this Standard, and that involves a risk of fire, electric shock, or injury topersons shall be evaluated using the appropriate additional component and end-product requirements asdetermined necessary to maintain the acceptable level of safety as originally anticipated by the intent of thisStandard.A product whose features, characteristics, components, materials, or systems conflict with specificrequirements or provisions of this Standard cannot be judged to comply with this Standard. Where consideredappropriate, revision of requirements shall be proposed and adopted in conformance with the methodsemployed for development, revision, and implementation of this Standard.
1.2 Type of blades
1.2.1 These requirements apply to blades, solid and folded, of attachment plugs and current taps rated 15 or20 A, for general purpose use. These requirements do not apply to the grounding blade (pin) of grounding type
attachment plugs or current taps.
1.3 Conductor sizes
1.3.1 These requirements apply to blades intended to be attached to Nos. 18 AWG (0.82 mm?) — 10 AWG (5.3mm~) conductors.
2 Glossary
2.1 For the purpose of this Standard the following definitions apply.
2.2 BLADE — The part of an attachment plug or current tap intended to be inserted into the contacts of an outletdevice of matching configuration and the integral extension of this part, located within the attachment plug orcurrent tap, to which the conductor of a flexible cord is connected.
2.3 CONTACT SURFACE AREA- The area on each side of a blade that is intended to make electrical contactwith the contacts of an outlet device
2.4 CRIMPED CONNECTION – An electro-mechanical connection made between a blade and a conductorby compressing the portion of the blade, termed “the integral extension” in 2.2, against the conductor.
3 Units of Measurement
3.1 lf a value for measurement is followed by a value in other units in parentheses, the second value may beonly approximate. The first stated value is the requirement.
