For any plastic used in electronics, appliances, or electrical housings, how it behaves in a fire can decide whether a product passes certification — or gets recalled. UL 94 flammability testing chennai manufacturers depend on classifies how a plastic burns, self-extinguishes, or drips, while LOI testing measures the minimum oxygen a material needs to keep burning. At Kiyo R&D Lab, we run UL 94 flammability testing chennai businesses can trust, with controlled conditions and clear, defensible reporting.
Whether you are qualifying a flame-retardant grade, verifying an incoming batch, or meeting a buyer’s safety specification, accurate UL 94 flammability testing chennai gives you the classification your certification needs. Our team handles specimen preparation, conditioning, and testing in-house so your results hold up to any customer audit.
UL 94 flammability testing chennai classifies how a plastic responds to a flame — whether it self-extinguishes, how long it burns, and whether it drips flaming particles. LOI testing (limiting oxygen index) complements it by measuring the minimum oxygen concentration a material needs to sustain burning. The table below shows the common UL 94 ratings.
| Rating | What It Means |
|---|---|
| V-0 | Stops burning within 10s, no flaming drips |
| V-1 | Stops within 30s, no flaming drips |
| V-2 | Stops within 30s, flaming drips allowed |
| HB | Slow horizontal burn (least stringent) |
| 5VA / 5VB | Most stringent, for enclosures |
A correct UL 94 flammability testing chennai service reports the rating, specimen thickness, and orientation, because a material’s rating is only valid at the thickness tested.
UL 94 gives a pass/fail classification that certification bodies recognise, while LOI testing gives a numerical oxygen-index value useful for ranking and development. Running both means UL 94 flammability testing chennai teams get a compliance result and a research-grade number from the same material, which is ideal when developing a flame-retardant grade.
For electronics and appliance makers around Chennai, having this capability close by means faster iteration on flame-retardant formulations and quicker certification support.
Flammability behaviour can make or break a product’s certification, so it deserves a precise, standard-aligned test. With Kiyo R&D Lab’s UL 94 flammability testing chennai and LOI testing, you get both a recognised flame classification and a numerical oxygen-index value, with NABL-accredited reporting where applicable.
Send us your material and the rating you need to hit, and our Chennai team will prepare specimens, run the test, and get you defensible results fast.

Our UL 94 flammability testing chennai service follows UL 94 for plastic classification, with LOI testing to ASTM D2863 / ISO 4589. Accredited reporting is available for methods within our NABL scope; we confirm the exact status for your test before you commit.
UL 94 is a pass/fail flame classification (V-0, V-1, etc.); LOI testing gives a numerical minimum-oxygen value. UL 94 flammability testing chennai work often pairs both for a complete picture.
Yes — a rating is only valid at the thickness tested, so the same material can be V-0 at one thickness and V-2 at another. We always report the thickness with the result.
Our UL 94 flammability testing chennai provides the test data to the UL 94 method; formal UL listing/certification is issued by UL itself. We give you the evidence used toward it.
Moulded bars at the thickness you want rated. We confirm specimen dimensions, thickness, and count when we scope your job.
