Questions a plastic company can ask APC to determine what material to recommend1. What is the product Type?a.UPSb.Surge Strip2. What Markets will the product sell ina.North Americab.Europec.South America3. Does the product weigh more than 18kG4. Will the product be permanently mounted/installed?5. Is the plastic part used for:a.the fire enclosure?b.NEMA receptaclec.European receptacled.Support of live partse.Decorative partf.Internal part6. What is the max temperature the plastic part gets to?The results of these questions will send you down different paths.Here are some general items that will fill in the blanks for the correct part depending on the usage by APC:I.Flame rating:Enclosure: UPS94V-1 if not wall mountable or less than 18Kg5VB minimum if rack mountable or greater than 18Kg.Until further notice CSA requires 5VA Surge Strip:94V-2 for US/CSAReceptacles: V2 minimum for North America. V0 for EU, or 5V if greater than 18Kg or rack mountableInternal part: V2 minimumDecorative bezel: HBII.RTI If we get above 65C for use temp then RTI must be the same as max use temp. Should always try to stay close to Vicat. III.Vicat/Heat Deflection: Again, this depends on the applicationEnclosure: Max use temp, plus 10C, but no less than 70C (Mold stress for 7 hours)Receptacles: North America: Max use temp, plus 10C, but no less than 70C (Mold stress for 7 hours)Europe: Max temp plus 40C, but not less than 125(Ball deflection for 1 hourSupport of live parts(other than receptacles)North America: Max use temp, plus 10C, but no less than 70C (Mold stress for 7 hours)Europe: Max temp plus 40C, but not less than 125(Ball deflection for 1 hourIV.HWI: North America onlyThis is a measure of how well the plastic resists ignition from heat. Measured by a PLC (Performance Level Characteristic) Bar specimens have a heater wire wrapped around them and the time to ignition is measured. PLC rating is then assignedMean Ignition TimePLC rating120= IT060=IT 120130= IT 60215= IT 3037= IT 3040= IT 75V.HAI: North America onlyThis is a measure of how well the plastic resists combustion in the presence of High current (32.5A) Arcs: Measured by PLC. Two electrodes are allowed to arc to one another across the surface of the plastic. The number of arcs until ignition determines the PLCMean number of arcs to ignition (NA)PLC120=NA060= NA120130= NA60215= NA3030= NA154.VI.CTI: North America onlyThis measures how well the board allows voltage to creep (or track) as it becomes polluted: PLC ratings are as follows:Tracking Index (TI)PLC600=TI0400= TI 6001250= TI 4002175= TI 2503100= TI 17540 = TI 1005.Below are the required HAI, CTI, and HAI depending on the flammabilityFor a UPS:V-0V-1V-2HAI322CTI444HWI432For a surge stripV-0V-1V-2HAI333CTI333HWI433Lets pick a few examples:1.The part is an enclosure that supports live parts for use in Europe and the max temp it gets to is 67 degrees C. The UPS is not permanently connected and is less than 18kGThe part will need to be 94V-0, have a RTI of at least 67 and a Vicat of at least 1272.The part is a rear panel for a UPS that is intended for US/Canada, weighs less than 18kg, is portable and is used for the receptacle. The max temp we are allowed is 55.The part will need to be 5VA, RTI does not matter but it will need HAI of 3, HWI of 4 and CTI of 43.The part is a surge strip enclosure, it is also part of the receptacle, it is less than 18kG, portable, sold in US/Canada and it gets to 73 d
