Full title and description

ISO 10047:1993 — Textiles — Determination of surface burning time of fabrics. This International Standard specifies a laboratory method for measuring the time taken for flame to spread down the raised surface (napped, pile, tufted, flocked or similar) of a textile specimen when mounted vertically and ignited under defined conditions.

Abstract

The method supports a dry specimen on a vertical plate, ignites the raised surface near the top and times the spread of flame downwards to a reference line. It applies specifically to fabrics with a raised fibre surface and provides repeatable measurement of surface burning time for comparison and classification.

• ICS / categories: 13.220.40 (Ignitability and burning behaviour of materials and products); 59.080.30 (Textile fabrics).
• Edition / version: Edition 1 (1993).
• Number of pages: 7 pages.

Scope

This standard gives a test procedure for measurement of surface burning time of textile fabrics that have a raised fibre surface (napped, pile, tufted, flocked or similar). The scope covers specimen preparation, apparatus (vertical plate and specified gas burner), ignition procedure, timing, conditioning and reporting of results; it is intended for laboratory comparison of such fabrics rather than for full product fire-hazard assessment.

Key topics and requirements

• Specification of specimen holder (vertical plate, exposed area and reference mark locations).
• Defined ignition source and burner geometry (requirements for burner and fuel such as commercial propane/butane).
• Controlled flame application time and timing procedures for flame spread to a reference mark.
• Conditioning and drying of specimens, and safety/ventilation considerations due to combustion products.
• Reporting of whether pile propagation or ignition occurred and measured surface burning time to the reference line.

Typical use and users

Used by textile test laboratories, product safety engineers, manufacturers of piled/nap fabrics (upholstery, apparel trims, carpets, technical textiles) and conformity assessment bodies to characterise the surface-burning behaviour of raised-fibre textiles for research, quality control and regulatory compliance contexts. These measurements are used alongside other flammability and reaction-to-fire tests in regulatory and product-safety programs.

Related standards

ISO 10047 sits within the textile flammability test family and is related to other ISO and regional standards addressing burning behaviour and flame-spread of textiles (for example ISO 6941 and related EN/EN ISO methods for vertically oriented specimens, and various CEN EN methods such as EN 1624). ISO/TC 38 is the responsible technical committee. ISO 10047:1993 has been revised by a newer edition (ISO 10047:2025).

FAQ

Q: What is this standard?

A: ISO 10047:1993 is an ISO laboratory test method titled "Textiles — Determination of surface burning time of fabrics", describing a vertical-surface flame-spread test for raised-fibre textile surfaces.

Q: What does it cover?

A: It covers specimen preparation, apparatus (vertical plate and specified burner), ignition procedure, timing of flame spread to a reference mark, specimen conditioning and reporting of results for fabrics with a napped, pile, tufted, flocked or similar raised surface.

Q: Who typically uses it?

A: Textile testing laboratories, manufacturers of piled/nap fabrics, product-safety engineers and conformity assessment/certification bodies use this standard for comparative testing, quality control and to support regulatory or client requirements.

Q: Is it current or superseded?

A: ISO 10047:1993 is recorded as withdrawn/superseded; it has been revised by a later edition (ISO 10047:2025). For current requirements and the formally published replacement, consult the ISO catalogue entry and the newer edition.

Q: Is it part of a series?

A: It forms part of ISO/TC 38's body of standards on the burning behaviour and flammability of textiles and is related to other ISO and EN methods (e.g., tests for vertically oriented specimens and other textile reaction-to-fire methods).
