1.QMFZ2的產品需按UL94(Maybe UL1694/723)做測試,但可能會參照到UL746A/B/C/D/E或ASTM的標準.
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."
2.RTI:
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.
3.關於94V0--就是滿足UL94的V0等級耐燃等級
4.CTI:
Comparative Tracking Index (CTI; ASTM D3638 ) — Expressed as that voltage which causes tracking after 50 drops of 0.1 percent ammonium chloride solution have fallen on the material. The results of testing the nominal 3 mm thickness are considered representative of the material's performance in any thickness.
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."
5.HAI:
High- Current Arc Ignition (HAI; ANSI/UL 746A ) — Performance is expressed as the number of arc rupture exposures (standardized as to electrode type and shape and electric circuit) that are necessary to ignite a material when they are applied at a standard rate on the surface of the material.
6.HWI: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.
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."

是在台灣還是大陸工作?請看清第1點,測試程序要看你可能選用的標準了.每個標準有不同的測試程序.可能要根據你的產品用途來確定可能會選用的標準,另你還得定位你的產品是不是就是要申請V-0等級的耐燃等級.
歡迎台灣同胞過我們的安規認證論壇來交流技術!絕無廣告!

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:

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.

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

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.
