仔細(xì)一看,樓主還是臺(tái)灣同胞(簽名如下),難得:
來(lái)自對(duì)岸的同袍~

謝謝FASTEN大哥的說(shuō)明~這樣有比較清楚了!謝謝

不客氣!均摘自UL本身網(wǎng)站!

恩 沒(méi)錯(cuò)!我是臺(tái)灣人~

看FASTEN大哥的說(shuō)明,應(yīng)該對(duì)塑膠材質(zhì)認(rèn)證方面有研究!
不知你有辦法幫我列出UL測(cè)試程序(TEST PROGRAM)嗎?
我想了解整個(gè)測(cè)試流程與項(xiàng)目,這樣對(duì)於我司的產(chǎn)品
比較好做評(píng)估,節(jié)省摸索時(shí)間~ 感恩喔~

謝謝大哥的回覆!
塑膠材質(zhì)測(cè)試評(píng)估的相關(guān)標(biāo)準(zhǔn)在UL746A、B、C沒(méi)錯(cuò)
只是UL62我看過(guò),似乎沒(méi)針對(duì)材質(zhì)的測(cè)試項(xiàng)目...

是在臺(tái)灣還是大陸工作?
請(qǐng)看清第1點(diǎn),測(cè)試程序要看你可能選用的標(biāo)準(zhǔn)了.每個(gè)標(biāo)準(zhǔn)有不同的測(cè)試程序.可能要根據(jù)你的產(chǎn)品用途來(lái)確定可能會(huì)選用的標(biāo)準(zhǔn),另你還得定位你的產(chǎn)品是不是就是要申請(qǐng)V-0等級(jí)的耐燃等級(jí).

歡迎臺(tái)灣同胞過(guò)我們的安規(guī)認(rèn)證論壇來(lái)交流技術(shù)!絕無(wú)廣告!

炎黃同胞.我以前做過(guò)一個(gè)最簡(jiǎn)單的QMFZ2, 即一個(gè)ABS的型號(hào)申請(qǐng)UL94V-0, 當(dāng)然是按UL-94的標(biāo)準(zhǔn)來(lái)檢測(cè). 如果塑料粒子除阻燃等級(jí)外還要申請(qǐng)其他性能,譬如溫度等,則還要按UL746A,B來(lái)檢測(cè).UL746A是短期性能評(píng)估,UL746B是長(zhǎng)期性能評(píng)估. 如果只申請(qǐng)阻燃等級(jí),則其溫度就當(dāng)作最小值.譬如PP當(dāng)做65攝氏長(zhǎng), ABS當(dāng)作60攝氏度.

誰(shuí)說(shuō)的UL62? UL62是軟線的,風(fēng)馬牛不相及.

大哥謝謝你的訊息!
因我司想要申請(qǐng)PVC的各項(xiàng)測(cè)試(UL746A、B的測(cè)試內(nèi)容)
所以要整理需求的測(cè)試項(xiàng)目,不知誰(shuí)能幫忙提供?

標(biāo)準(zhǔn)看不太懂=.="

好的!有空會(huì)去逛逛,謝謝喔!

標(biāo)準(zhǔn)最好要搞懂,這樣既有利于正確申請(qǐng),也有利于一次通過(guò)測(cè)試.
關(guān)于測(cè)試項(xiàng)目,你可以上www.ul.com網(wǎng)上點(diǎn)擊certification, 然后在UL CATEGORY下輸入QMFZ2.即可查到所有的UL塑膠粒子.
選幾個(gè)有名的生產(chǎn)廠,查查他們的PVC申請(qǐng)了一些什么性能,什么等級(jí).
譬如臺(tái)灣奇美公司,就有很多好塑膠粒子.

好的,謝謝大哥的指引!

Plastics - Component


The materials covered under this category are incomplete in certain constructional features or restricted in performance capabilities and are intended for use as components of complete equipment submitted for investigation rather than for direct separate installation in the field. THE FINAL ACCEPTANCE OF THE COMPONENT IS DEPENDENT UPON ITS INSTALLATION AND USE IN EQUIPMENT SUBMITTED TO UNDERWRITERS LABORATORIES INC.

GENERAL
This category covers materials that have been tested in accordance with established methods to define their properties in order to facilitate investigation of their use in end-use product applications. The tests may include the determination of material flammability (burning characteristics), ignition characteristics from various thermal and electrical sources, electrical tracking and other electrical characteristics, physical and mechanical characteristics, and analytical tests. In addition, the effect of long-term exposure to elevated temperature (air-oven aging), water, ultraviolet light, cold, etc., on property retention may be investigated. Levels of performance characteristics required for a particular end-use product application are intended to be in accordance with the requirements of the end-use product standard. Due to space limitations, only a limited number of property values may be presented in the individual Recognitions. Additional properties may be found in the UL iQ? for Plastics database at www.ul.com, or in the individual Reports.

In those cases where the materials have the same performance characteristics, with the exception of weathering resistance, they are tabulated together as a group with each material designation separated by a comma. The individual Recognitions may include alternate designations as well as materials that are basically similar in composition but differ by some minor variation, such as molecular weight, lubricants, colorants, etc.

The colors shown thereon are as pigmented by the material manufacturer; unless otherwise indicated, the property values are for the unpigmented (Natural color) material. Refer to Flame-retardant and/or Color Concentrates (QMQS2) and ANSI/UL 746D, "Polymeric Materials - Fabricated Parts," for limitations on the use of concentrates by the part molder or processor. The following abbreviations may be used in the individual Recognitions to represent the material color:

Flammability
Materials may be classified based on burning tests conducted in accordance with ANSI/UL 94, "Test for Flammability of Plastic Materials for Parts in Devices and Appliances," ANSI/UL 1694, "Tests for Flammability of Small Polymeric Component Materials," and ANSI/UL 723, "Test for Surface Burning Characteristics of Building Materials."

ANSI/UL 94 small-scale test data does not pertain to building materials, furnishings and related contents. ANSI/UL 94 small-scale test data is intended solely for determining the flammability of plastic materials used in the components and parts of end-use product devices and appliances, where the acceptability of the combination is determined by UL.

  TEST NAME (per ANSI/UL 94)

— V-2 VTM-2 HF-2 5VB
HB — — HBF Less Severe





Thermal Endurance
The temperature below which a class of critical property will not be unacceptably compromised through chemical thermal degradation, over the reasonable life of an electrical product (relative to a reference material having a confirmed, acceptable corresponding performance) is defined as the Relative Thermal Index (RTI). More than one RTI may be appropriate for a given material depending on the property requirements for a given application. In certain cases, higher temperatures are permitted if so specified by the end-use product standard.

RTI Elec — Electrical RTI, associated with critical insulating properties.
RTI Mech Imp — Mechanical Impact RTI, associated with critical impact resistance, toughness, elongation and flexibility properties.
RTI Mech Str — Mechanical Strength (Mechanical without Impact) RTI, associated with critical mechanical strength and structural integrity where impact resistance, resilience and flexibility may not be essential.
Resistance to Ignition and Tracking Properties
Performance may be investigated with respect to electrical track resistance, ability to resist ignition from electrical sources, and other electrical properties. In order to avoid an excessive level of implied precision and bias, material performances for several tests are recorded as Performance Level Categories (PLC), based on the mean test results (rather than recording the exact numerical results), as indicated in the table following the test description.


Hot-Wire Ignition (HWI; ASTM D3874, IEC 60695-2-20 ) — Performance is expressed as the mean number of seconds needed to either ignite standard specimens or to burn through the specimens without ignition.

PLC
0 through 10 0
10.1 through 25.4 1
25.5 through 80 2

High-Voltage, Low-Current Arc Resistance (D495; ASTM D495 ) — Expressed as the number of seconds that a material resists the formation of a surface conducting path when subjected to an intermittently occurring arc of high voltage, low current characteristics. The results of testing the nominal 3 mm thickness are considered representative of the material's performance in any thickness.

D495 Range
Mean Time of Arc Resistance

Less than 100 5

The above characteristics and dielectric strength, volume resistivity and other electrical and mechanical properties may be determined by means of the applicable ASTM and/or UL specification in ANSI/UL 746A, "Polymeric Materials - Short Term Property Evaluations."

In addition to minimum electrical and ignition test levels, materials that are used in applications involving support or contact with current-carrying parts are also required to display a minimum stability (heat distortion, moisture resistance, dimensional stability and mold stress) performance level, as described in ANSI/UL 746C, "Polymeric Materials - Use in Electrical Equipment Evaluations."



CONDITIONS OF ACCEPTABILITY
Unless specified otherwise in the individual Recognitions, consideration is to be given to the following Conditions of Acceptability when these components are employed in the end-use equipment:

1. Material traceability for parts covered under Fabricated Parts (QMMY2).
2. Material identification for a device employing parts molded of these materials should specify the parts' wall thickness, color, material identification, and traceability.
3. Materials must meet applicable requirements concerning the molding and fabricating of finished parts as described in ANSI/UL 746D, "Polymeric Materials - Fabricated Parts." This includes, but is not limited to, the restricted use of regrind thermoplastic material to amounts less than 25% unless specified in the individual Recognitions.
4. Unless otherwise indicated, suitability for use when exposed to weathering, oils, soaps, chemicals, x-rays, and the like has not been determined.
5. Investigation of parts for other properties in accordance with the applicable UL end-use product standard and/or requirements outlined in ANSI/UL 746C.
Additional Conditions of Acceptability may be found in the individual Recognition Report available from the manufacturer.

GENERIC MATERIAL SYMBOLS
The generic material symbols are based upon the terminology developed in the International Organization for Standardization publications ISO 1043, "Plastics - Symbols and Abbreviated Terms," and ISO 1629, "Rubber and Latices - Nomenclature."

  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  



FOAMED MATERIALS
Materials that have been foamed with the introduction of a chemical blowing agent or inert gas may have significantly different properties than the unfoamed or solid material form; therefore, ratings that are established for solid (unfoamed) material do not automatically apply to the foamed version of that same material.

MATERIALS FOR USE IN SPECIAL ENVIRONMENTS
Investigation of materials for specific end-use product applications where requirements exist for the retention of properties after exposure to certain critical operating and/or environmental conditions may be indicated in the individual Recognitions.
