 Flammability Materials may be classified based on burning tests conducted in accordance with ANSI/UL 94, "Tests 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, and 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) Horizontal Burning Test 20 mm Vertical Burning Test Thin Material Vertical Burning Test Horizontal Burning Foamed Material Test 500 Watt (125 mm) Vertical Test Flame Rating Hierarchy — V-0 VTM-0 — More Severe 5VA — V-1 VTM-1 HF-1 ↑ ↑ ↑ — V-2 VTM-2 HF-2 5VB HB — — HBF Less Severe Thermal Endurance The materials covered by this program have been investigated with respect to thermal endurance of certain critical properties. The investigation was performed as part of a long-term thermal-aging program or based on historical record in accordance with ANSI/UL 746B, "Polymeric Materials - Long Term Property Evaluations." 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 ignite standard specimens (if the material ignited). An HWI PLC 0 may be due to all the test specimens melting away without any ignition. HWI Range Mean Ignition Time (in sec) Assigned PLC 120 and longer 0 60 through 119 1 30 through 59 2 15 through 29 3 7 through 14 4 Less than 7 5 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. HAI Range Mean Number of Arcs to Cause Ignition Assigned PLC 120 and greater 0 60 through 119 1 30 through 59 2 15 through 29 3 Less than 15 4 High-voltage-arc Tracking Rate (HVTR; ANSI/UL 746A) — Denoted as the rate, in mm/min, that a tracking path can be produced on the surface of the material under standardized test conditions. A notation is made if ignition on the material takes place. The results of testing the nominal 3 mm thickness are considered representative of the material's performance in any thickness. 代理范圍: (一)水平燃燒測(cè)試,94HB,并指導(dǎo)前期打樣送測(cè); (二)垂直燃燒測(cè)試,94V-2,94V-1,94V-0,并指導(dǎo)前期打樣送測(cè); 電子線(xiàn)UL758認(rèn)證，燈具UL認(rèn)證，電線(xiàn)電纜UL認(rèn)證，QMMY2 UL746D注塑件認(rèn)證，UL969 PGDQ2標(biāo)簽認(rèn)證，連接器UL認(rèn)證，燈飾CCC認(rèn)證，線(xiàn)路板組裝VZQC2認(rèn)證，UL969 PGAA標(biāo)簽認(rèn)證，UL588圣誕產(chǎn)品認(rèn)證，軟線(xiàn)UL62認(rèn)證代理，PCBA線(xiàn)路板組裝ZPVI2認(rèn)證，電容UL認(rèn)證，開(kāi)關(guān)UL認(rèn)證，網(wǎng)絡(luò)線(xiàn)UL444認(rèn)證，鋰電池、鎳錳電池UL認(rèn)證，水晶頭UL1863認(rèn)證，導(dǎo)電泡棉UL認(rèn)證，光伏電纜UL認(rèn)證，UL817插頭認(rèn)證，ECBT2 UL1997連接器認(rèn)證，熱縮套管UL認(rèn)證，功率線(xiàn)UL13認(rèn)證，UL507直流交流風(fēng)扇認(rèn)證，UL最新RSCS環(huán)保認(rèn)證，阻燃套管UL認(rèn)證，火災(zāi)報(bào)警線(xiàn)UL1424認(rèn)證，UL2089車(chē)載充電器認(rèn)證，UL1059端子臺(tái)認(rèn)證，塑膠電鍍處理UL認(rèn)證，光纖UL1651認(rèn)證，UL355卷線(xiàn)器認(rèn)證，UL486接線(xiàn)端子認(rèn)證，UL486接線(xiàn)端子認(rèn)證 塑膠料QMFZ2認(rèn)證，UL764線(xiàn)束認(rèn)證，UL310快接端子認(rèn)證，UL1446絕緣系統(tǒng)認(rèn)證，開(kāi)關(guān)VDE認(rèn)證，各國(guó)電線(xiàn)電纜認(rèn)證，各國(guó)插頭認(rèn)證 詳詢(xún)Sunny陶13913142465 QQ1822971259 |
