請(qǐng)問各位大俠,Wiring Harnesses的具體定義是什么啊??
什么樣的產(chǎn)品才算是Wiring Harnesses ????

本人的理解:
“線束加工”一般是指外購(gòu)或自行生產(chǎn)電線(一定要有認(rèn)證)和端子,再采用注塑、焊接等方式生產(chǎn)出適用于一些整機(jī)產(chǎn)品或設(shè)備的線束.
UL有這種認(rèn)證,原文如下:
Wiring Harnesses - Component
The devices covered under this category are incomplete in certain constructional features or restricted in performance capabilities and are intended for use as components of complete equipment submitted for investigation rather than for direct separate installation in the field. THE FINAL ACCEPTANCE OF THE COMPONENT IS DEPENDENT UPON ITS INSTALLATION AND USE IN COMPLETE EQUIPMENT SUBMITTED TO UNDERWRITERS LABORATORIES INC.
USE
This category covers wiring harnesses intended solely as factory-installed components of other equipment. These wiring harnesses are not intended for field installation.
Each wiring harness is normally constructed in accordance with a harness diagram and is generally designed for a specific application which is indicated on the diagram or carton marking.
REQUIREMENTS
The basic standard used to investigate products in this category is UL 817, "Cord Sets and Power Supply Cords."
The Recognition Mark of Underwriters Laboratories Inc. (as illustrated below) on the smallest bundle or unit container in which the product is packaged is the only method provided by UL to identify these products manufactured under its Recognition and Follow-Up Service.

做Wiring Hamesses認(rèn)證只需要申請(qǐng)一次UL認(rèn)證就行了.送最複雜的樣品.

@littleforward
Wiringharnesses的定義如FANCY所講,但一般是不進(jìn)行注塑的流程,這也是UL判斷您的工藝是否是Wiringharnesses加工的重要依據(jù).若有注塑工藝,就可能有新的產(chǎn)品產(chǎn)生,就不能視為Wiringharnesses加工了.申請(qǐng)時(shí)UL工程師會(huì)讓您提供一份wiringharnesses的圖紙,用以判斷是否具備條件.一般不送樣品.
請(qǐng)問一下,Wire harness在什么條件下需要做UL認(rèn)証呢?如果在次級(jí)部分也需要嗎?
