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.

Thermal Endurance
The materials covered by this program have been investigated with respect to thermal endurance of certain critical properties. The investigation was perbed 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 perbance) 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
Perbance 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 perbances for several tests are recorded as Perbance Level Categories (PLC), based on the mean test results (rather than recording the exact numerical results), as indicated in the table following the test debion.
Hot-wire Ignition (HWI; ASTM D3874, IEC 60695-2-20) — Perbance 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

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) — Perbance 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 perbance in any thickness.
