Heat-treatment Fiberglass Sleeving, View Fiberglass Sleeving ...

Fiberglass sleeving is often used in many different types of electrical products.  It is used to insulate from heat.  It is used to hold wires together.  It is used to cover splices.    It comes in different materials for different applications. 

 

It is important to know there are difference types of sleeving and although it says UR, it may be the wrong UR category.  There are two main categories UL Recognizes Sleeving under – Flame Retardant and Coated Electrical.  The last thing you want to do is pick the wrong one, order 100,000 feet of it, go into production only to find out 2 weeks before shipping it is UR in the wrong category.

 

 

UZIQ2.GuideInfo - Sleeving, Flame Retardant – Component

 

CONDITIONS OF ACCEPTABILITY

Consideration is to be given to the following Conditions of Acceptability when these components are employed in the end-use equipment:

1. This sleeving has not been investigated for any electrical or mechanical capabilities.

2. This sleeving has not been investigated to determine its thermal performance.

3. This sleeving has not been investigated for use in contact with sharp edges, corners, projections or burrs, or where subject to tension, compression, abrasion, repeated flexing or where exposed to ultraviolet radiation or oil contamination.

 

 

UZFT2.GuideInfo - Sleeving, Coated Electrical - Component

 

CONDITIONS OF ACCEPTABILITY

Consideration is to be given to the following Conditions of Acceptability when these components are employed in the end-use equipment:

1. Sleeving shall not be used over the maximum voltage rating.

2. Sleeving shall not be used over the maximum temperature rating.

3. The minimum wall thickness of the sleeving shall comply with the requirements of the end product.

4. Sleeving marked "Oil Resistant 60°C " or "Oil Resistant 80°C" has been investigated for intermittent or occasional contact with oil not exceeding the oil rating.

5. Sleeving marked "VW-1" has been investigated using a fine wire support in conducting the flammability test.

6. Sleeving is not acceptable for use in contact with sharp edges, corners, projections or burrs , or where subjected to tension, compression, abrasion or repeated flexing without additional testing.

7. Sleeving is not recommended for use where it is feasible to employ a standard insulated conductor (appliance wiring material) intended for the purpose.

8. Sleeving shall be used in dry and damp locations only as defined in ANSI/NFPA 70, "National Electrical Code."

The reality is that most people think that getting a product certified by UL, ETL, CSA, or another NRTL is a relatively easy task. After all, product development engineers know how to design safe products – so confirming it with testing should be a smooth process. This is a great theory, but the opportunities for test failures and non-compliances are literally endless, without knowing exactly what engineers who work for major NRTLs are looking for.

 

Ideally, a product should be submitted as early as possible during its development. Because we know the value added when you build solutions into products up front, we created Design For Safety Approvals – DFSA™. Bring us in at the front-end. Save your company lost time, money and customers by understanding the compliance requirements in detail before products come off the drawing board.
