Determining that components used in UL Certified products are consistent with their descriptions in the “UL Follow-Up Service Procedure” is key to verifying compliance with UL requirements. Determining compliance of components used in UL Certified products is also an important step in bringing safer products to market. Additionally, maintaining the traceability of these components helps support the ongoing integrity of the supply chain, resulting in higher levels of confidence that components being received meet sourcing requirements.

確定UL認證產品中所使用的組件與“UL Follow-Up Service Procedure”中的描述是一致的,這是驗證是否符合UL要求的關鍵。 確定UL認證產品中使用的組件的合規性也是將更安全的產品推向市場的重要一步。 此外,保持這些組件的可追溯性有助於支持供應鏈的持續完整性,從而使收到的組件符合採購要求的信心更高。

When cable manufacturers sell their products to distributors and/or processors, who in turn perform a processing or respooling operation, the original UL label may no longer accompany the product when it leaves the distributor and / or processor. The original UL label provides evidence of UL Certification while the surface printed UL logo on the cable is a supplemental means of traceability and is not the primary evidence of UL Certification.

當電纜製造商將其產品銷售給經銷商和/或處理商時,經銷商和/或處理商進而執行處理或重新分配操作,當產品離開經銷商和/或處理器時,原始UL標籤可能不再伴隨該產品。 原始UL標籤提供UL認證證據,而電纜上的表面印刷UL標誌是可追溯性的補充手段,並非UL認證的主要證據。

Without evidence of UL Certification, the end-user may encounter traceability issues and / or held shipments if they cannot prove the cable they sourced as a component in their end product is in fact a UL Certified cable. Traceability issues are not limited to end-product manufacturers. If processed or respooled cables are sold directly to installers, construction may be halted by an authority if the installer is unable to provide evidence of UL Certification for the cables they are installing. The proliferation of counterfeit and substandard cable products in the marketplace makes the verification of UL Certification status more critical than ever to end users, from OEMs to installers.

如果沒有UL認證的證據,最終用戶可能會遇到可追溯性問題和/或持有貨物,如果他們無法證明他們作為最終產品中的組件採購的電纜實際上是UL認證電纜。 可追溯性問題不僅限於最終產品製造商。 如果處理或重新處理的電纜直接銷售給安裝人員,如果安裝人員無法為他們正在安裝的電纜提供UL認證證據,則可由主管機構停止施工。 市場上假冒和劣質電纜產品的激增使得UL認證狀態的驗證對於最終用戶(從OEM到安裝商)比以往任何時候都更加重要。

To help support supply chain integrity while meeting the traceability needs of end users and ensuring that safe products make it to the market quickly, UL offers three traceability programs for wire and cable distributors and processors, detailed below:


Certified Processed Wire and Respooled Wire (ZKLU, ZKLU7) 經過認證的加工電線和再生電線(ZKLU, ZKLU7)

– This program provides traceability for a variety of Listed and Classified wire and cable types that have been subjected to processing after original manufacturing and UL labeling. This processing may include cutting to specified lengths, insulation stripped from one or both ends, soldering/tinning of the stripped ends and / or the attachment of simple terminations. These processed products would bear a UL Certified “Processed Wire” label, which is available in various piece count denominations. This program also covers respooling into smaller quantities, but respooled products would bear a UL Certified “Processed Wire Respooled” label. The label is applied to each respooled length and has no denomination. The Processed / Respooled label is attached to the tag, reel or smallest unit container into which the product is packaged. The distributor / processor is responsible for transferring onto their own tags all engineering tag markings provided by the original wire manufacturer.


Recognized Component Processed Wire and Respooled Wire (ZKLU2, ZKLU8) 公認的元件加工電線和重新焊接的電線(ZKLU2, ZKLU8)

 – The scope of this program is the same as the UL Certified Processed Wire and Respooled Wire program; however, it only covers the processing or respooling of Recognized Component Appliance Wiring Material (AWM).

該方案的範圍與UL認證的加工線和重新佈線計劃相同; 但是,它僅涵蓋認可組件設備佈線材料(AWM)的處理或重新匯總。

Recognized Component Wiring Harnesses (ZPFW2, ZPFW8) 公認的元件線束(ZPFW2,ZPFW8

– This program provides traceability for wiring harnesses that are assembled at off-site locations and intended for use as factory installed components at an end-product manufacturing facility. Harnesses are defined as components consisting of two or more wires joined electrically and / or mechanically, and may include connectors, plugs, strain reliefs, splices, etc. Harnesses should be constructed in accordance with a harness diagram or engineering specification provided by the end-product manufacturer. A UL Representative will verify that the components used in the manufacture of the harness comply with the end-product manufacturer’s requirements. One of the verifications will include the UL Certification status for the wire used in the harness and whether it was sourced directly from a UL Certified cable manufacturer or from a UL Certified respooled. If the harness is determined to be in compliance, it may be shipped with the UL Recognized Wiring Harness label. Additional traceability counterchecks are determined at the end-product manufacturing location to assure that   all harness features comply with the end-product Follow-Up Service Procedure. Harnesses may be labeled individually or in bulk quantities.

該方案提供了在非現場位置組裝的線束的可追溯性,旨在用作最終產品製造工廠的工廠安裝組件。線束被定義為由兩個或更多個電氣和/或機械連接的線組成的部件,並且可以包括連接器,插頭,應變消除裝置,接頭等。線束應該根據線束圖或工程規範來構造。產品製造商。 UL代表將驗證線束製造中使用的組件是否符合最終產品製造商的要求。其中一項驗證將包括線束中使用的電線的UL認證狀態,以及它是直接來自UL認證的電纜製造商還是來自UL認證的電纜。如果確定線束符合要求,則可以附帶UL認可的線束標籤。在最終產品製造地點確定額外的可追溯性計數器,以確保所有線束功能符合最終產品後續服務程序。線束可以單獨標記或批量標記。

As these are traceability programs, minimal to no testing is involved in establishing a UL Certification and turnaround time is quick. Standard labels are also available for each traceability program for immediate use by UL clients.

由於這些是可追溯性計劃,因此建立UL認證涉及極少甚至沒有測試,並且周轉時間很快。 每個可追溯性程序也可使用標準標籤,供UL客戶立即使用。
