UL94 Flame Ratings for Cable Ties — V-0, V-1, V-2, HB Explained
Complete guide to UL94 flame ratings for cable ties: V-0, V-1, V-2, HB classifications. Understand which rating your application requires and which cable tie materials meet each standard.
Overview
UL94 is the Standard for Safety of Flammability of Plastic Materials — the industry benchmark for assessing how plastic materials burn. This guide explains each rating, the test methodology, and which of our cable tie materials achieve each classification.
Key Standards & Requirements
| Standard | Description |
|---|---|
| V-0 | Self-extinguishes within 10 seconds. No flaming drips. Required for enclosed electrical compartments, railway interiors. |
| V-1 | Self-extinguishes within 30 seconds. No flaming drips. Suitable for industrial control panels. |
| V-2 | Self-extinguishes within 30 seconds. Flaming drips permitted. General-purpose indoor applications. |
| HB | Horizontal burn — slow burning. Minimum flammability rating for electrical components. |

Frequently Asked Questions
Which UL94 rating do I need for control panel cable ties?
For industrial control panels to UL 508A, V-2 is minimum. For plenum spaces or critical infrastructure, V-0 is strongly recommended.
What is the difference between UL94 V-0 and halogen-free?
UL94 V-0 measures flammability. Halogen-free measures material composition. A material can be V-0 but not halogen-free, and vice versa.
Do stainless steel cable ties have a UL94 rating?
Stainless steel is inherently non-combustible and does not require a UL94 rating. It is the ultimate fire-safe cable tie material.
