UL is USA 保险商 experiment/testing 室（Underwriter Laboratories Inc. ） 简写, UL Yellow Card, is in UL can 时, in   UL 注册 材 material or parts data mono. this data 汇集而 formed small 册子称 is 黄皮书. is 方便记录 testing data, UL 以特定 文字, data and other in Yellow Card 体现出. UL   is USA most tool 权威, is world upper from safety experiment/testing and relatively large 第三方 testing machine 构, is 一 独立, non 营利, is safety experiment/testing machine 构.



UL Yellow Card 建立起源
in 19世纪90  year 代, types testing new type connectors in USA large 城市造 formed speed 蔓延 火灾, more 数火灾 is short or similar causes 导致. is 避免此 type 悲剧, WilliamH. Merril  in 1894  year positive 式建立 火险 electrical 局（UnderwritersElectrical Bureau）. rear 该组织改名 is “国家火险商会 electrical 局（ElectricalBureau of the National Board of Fire Underwriters ）”. this is UL front 身.   UL 实验室 from 两 员工 and 不足 350美金起家 . 第一份 testing report 发行于1894 year  3 month 24 day.
1901 该局改 made is company  “UnderwritersLaboratories Inc.” (UL).  company formed make UL testing field/area 不限于 electrical engineering. to in ultra-  100 year history, make UL formed is world 领先 独立, 第三方 testing certification machine 构.   UL in USA has 五 实验室, 总部设 in add 哥北部 Northbrook镇, meanwhile in Taiwan  , 苏州, and separation 别设立 versus 应 实验室. UL currently certification already has full important market.



UL Yellow Card parameters 含义





how to UL Yellow Card （SABIC PC-945 Yellow Card ）

UL Yellow Card material features:
1, testing product thick thin degree: mono is mm mm, most large thick degree  12.7mm;
2, anti and other grade: from low to high is HB < V-2 < V-1 < V-0 < 5VB < 5VA;
3, versus for temperature degree 指数(RTI): is 指该材 material long hot aging temperature degree, is heat deflection temperature (HDT);
4, hot filament 引燃(HWI): is hot filament testing and hot filament testing, grade 别数字越 large material easy 燃烧;



UL Yellow Card electrical properties:
1, high electrical 弧燃烧指数(HAI): grade 别数字越 small, material flame resistant 烧（ 1 grade is 1-2 separation 钟,  4  grade is 7-15秒钟）;
2, high electrical pressure electrical 弧起痕指数(HVTR): is 指该材 material mono time electrical 弧径迹行进距离, and other grade small speed degree slow;
3, resistant electrical retardant resistant (D495): 由 ASTM设立 一 types resistant electrical property specifications;
4, versus ratio resistant electrical 起痕指数(CTI): this is material insulation property can non important parameters. resistant electrical 弧径迹 property types indicators. resistant electrical pressure value separation is  0～5 grade, 数字越 small resistant electrical 弧径迹 property high;
