Hello, UL 94V-0 is applied to small scale (approx. 5 in by 1/2 in by min. thickness) sample tests on polymeric materials. The IEC/UL60950-1 standard which applies to your product, has alternative tests which can be applied to the complete end-product enclosure. Flammability rating of an enclosure is determined by assessing whether you have a fire enclosure or an electrical enclosure or both a fire and electrical enclosure. If you determine by abnormal testing such as opening and shorting of components, overcharge and discharge there is no risk of fire, based on the standard a fire enclosure is not required and you can get away with the less stringent flammability requirements required of electrical enclosures. If you determine by tests that there is no risk of electric shock or energy, you can get away with the least flammability requirements required for decorative parts ( 94HB or end-product flame test allowed in the standard). When performing the abnormal tests specified above, please be aware that some batteries are previously approved and may or may not have internal protection. Best Regards, PETER S.

When, or rather on what products, does the UL94V0 burn test apply? If the electronic product is battery powered with less than 5V, must it meet this rating? If the battery is Li? Product is portable, contains GPS receiver, and has a 2.4 RF modem. Any 'gotcha' requirements should be aware of? - This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
