ASTM E1535-93 (2006) PDF

Full title and description

St ASTM E1535-93 (2006) — an ASTM International standard test method originally published in 1993 and issued in the form referenced here with a 2006 reapproval or revision designation. The document defines a laboratory test procedure for evaluating the flammability/fire-behavior characteristics of materials and small assemblies under controlled conditions and provides requirements for apparatus, specimen preparation, test execution, data reduction, and reporting.

Abstract

This standard describes a repeatable small-scale laboratory test intended to produce comparative data about the propensity of a material or small assembly to ignite, sustain combustion, and develop flame spread and heat release under specified conditions. The method covers equipment set-up, conditioning of test specimens, ignition and measurement procedures, and the format for presenting results so that manufacturers, test laboratories, and regulatory authorities can assess and compare material performance.

General information

• Status: Issued as E1535-93 with a 2006 reapproval/revision designation; users should confirm current status with ASTM International.
• Publication date: 1993 (document bears 2006 reapproval/revision note).
• Publisher: ASTM International (formerly American Society for Testing and Materials).
• ICS / categories: Fire testing; building and construction materials; material flammability test methods.
• Edition / version: E1535-93 (2006) — original 1993 edition with 2006 reapproval/revision reference.
• Number of pages: Typically a short method (commonly in the range of 4–12 pages depending on printing/format); actual page count should be confirmed on the official document.

Scope

The standard provides a procedural test for assessing surface-flammability and early-stage fire behavior of materials and small assemblies in a laboratory environment. It is intended for comparative evaluations (ranking and quality control) rather than for predicting full-scale fire performance. The scope defines specimen geometry and preparation, required test apparatus and instrumentation, environmental conditioning, ignition source specification, measurement of time-to-ignition, flame spread and related observations, and the required reporting elements so results are reproducible between laboratories.

Key topics and requirements

• Required test apparatus and instrumentation (burner/ignition source, holder, measurement sensors, and data acquisition).
• Specimen size, orientation, mounting, and conditioning (temperature and humidity control prior to test).
• Ignition procedure (positioning, duration, and energy of ignition source) and safety precautions.
• Measured endpoints such as time-to-ignition, extent of flaming, flame spread behavior, and qualitative observations of smoking or dripping.
• Data reduction, allowable tolerances, and how to report results (tabular and descriptive reporting formats).
• Limitations and intended use — comparative laboratory evaluations, not a full-scale fire prediction tool.

Typical use and users

Typical users include product manufacturers (materials, textiles, coatings, components), independent testing laboratories, quality control teams, product safety engineers, and code or regulatory compliance officers seeking comparative flammability data for product development, specification, acceptance testing, or documentation. Researchers and academics conducting material fire-performance studies may also use the method for bench-scale investigations.

Related standards

Commonly referenced companion or related standards in the area of material fire testing include other ASTM fire test methods (for example tests addressing surface burning, flame spread, and heat release) and international test methods. Typical related standards include ASTM methods used for surface burning classification and heat-release rate assessment as well as corresponding ISO test methods. Users commonly consult multiple standards to obtain a comprehensive view of material fire behavior for different test scales and purposes.
