Textile floor coverings — Guidelines for installation and use on stairs

This document provides recommendations for the installation and use of textile floor coverings on stairs for both residential/domestic and contract/commercial purposes. It covers all products composed of textile material with a pile or non-pile use surface including the use of such products in tile form. This document is applicable only to carpets that are intended to be installed without the use of protective stair nosings. For carpets that are intended to be installed using protective stair nosings, the overall use class determines the stair suitability. NOTE 1 The use of stair nosings/edgings in public areas is often the subject of local bye-laws and legislations. NOTE 2 In many split-level dwellings, a room can have one or two steps between different levels. This situation differs from a stairway in several important respects: — the steps are usually wider and therefore traffic intensity in any one place is usually lower; — the carpet can be bent over steps in either the machine direction or the across-machine direction. On a stairway, it is normal practice to lay the carpet with the pile lying down the stairs.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).

Introduction
Although the aspect of suitability of carpets for use on stairs is worldwide, different countries
have approached its solution from different perspectives, e.g. not guaranteeing carpets on stairs,
recommending that carpets be periodically moved on stairs, accepting that the wear life on stairs can
be half that in the equivalent flat location, use of proprietary stair nosings, etc.
Associated with some of these perspectives is tacit acceptance of test methods, although no universal
test method exists to predict the property for all carpet types.
In order to define the perspectives more closely, ISO/TC 38/SC 12 (the then responsible TC) circulated
a questionnaire to its participating experts. From the replies, it became apparent that problems with
carpets on stairs can be centred on three different characteristics:
— wear to the backing, particularly on stair nosings;
— tuft loss;
— appearance retention on the treads.
The problem is further complicated by the fact that some countries suggest movement to even out
wear and appearance changes, and also that the use and type of underlay play an important part in the
subsequent performance of the carpet on stairs.
Over the years, in practice, EN 1307 proved to be satisfying on the issue of suitability of carpets for use
on stairs, so it was decided to bring this guideline in line with its Annex C.
For all the above reasons, it was agreed that, until test methods can be developed to cover all
eventualities, this document would be developed as guidelines for the installation and use of textile
floor coverings on stairs.

Textile floor coverings — Guidelines for installation and
use on stairs
1 Scope
This document provides recommendations for the installation and use of textile floor coverings on stairs
for both residential/domestic and contract/commercial purposes. It covers all products composed of
textile material with a pile or non-pile use surface including the use of such products in tile form.
This document is applicable only to carpets that are intended to be installed without the use of
protective stair nosings. For carpets that are intended to be installed using protective stair nosings, the
overall use class determines the stair suitability.
NOTE 1 The use of stair nosings/edgings in public areas is often the subject of local bye-laws and legislations.
NOTE 2 In many split-level dwellings, a room can have one or two steps between different levels. This situation
differs from a stairway in several important respects:
— the steps are usually wider and therefore traffic intensity in any one place is usually lower;
— the carpet can be bent over steps in either the machine direction or the across-machine direction. On a
stairway, it is normal practice to lay the carpet with the pile lying down the stairs.

4 Criteria for the assessment of stair suitability
4.1 General
The following general recommendations for the installation and use of textile floor coverings on stairs
should be taken in account:
— Foam backed carpets can be used on stairs if recommended by the manufacturer. Because of the
problem of fitting such carpets to stairs, it is preferable that they be totally adhered.
— When carpet tiles are used on stairs, protective stair nosings should be used.
— Special care should be taken in the selection of carpet underlays/carpet cushion to be used on stairs
in both domestic/residential and contract/commercial installations since stairs represent one of
the most demanding areas of use. In order to prevent premature wear, woven carpets with sewn
seams should be used in conjunction with a carpet underlay/carpet cushion which does not allow
the seams to be raised prominent above the general surface level. Thicker, high density underlays
help the carpet to resist wear over stair nosings.
4.2 Pile carpets
For pile textile floor coverings, the thickness of the pile above the substrate measured according to
ISO 1766 should be ≤ 12 mm.
NOTE Thicker carpets can be potential tripping hazards.
If the backing can be seen on a new, unused piece of the carpet when bent at 90° over a (12,5 ± 1) mm
radius, as long as the visible backing is not part of the design, the carpet should be deemed to be
unsuitable.
The appearance of each specimen is tested according to ISO 12951, test B
