Textile fabrics - Burning behaviour - Determination of ease of ignition of vertically oriented specimens (ISO 6940:1984, including Amendment 1:1993)
This standard specifies a method for measurement of ease of ignition of vertically oriented textile fabrics in the form of single or multi-component fabrics.
Textilien - Brennverhalten - Bestimmung der Entzündbarkeit vertikal angeordneter Proben (ISO 6940:1984, einschließlich Änderung 1:1993)
Die vorliegende internationale Norm beschreibt eine Methode zur Bestimmung der Entzündbarkeit von senkrecht angeordneten textilen Flächengebilden, die für Bekleidung, Vorhänge und Gardinen bestimmt sind. Es kann sich dabei um Einzel- oder Verbundtextilien (beschichtet, gesteppt, mehrlagig, Sandwich-konstruktionen und ähnliche Kombinationen) handeln.

La CEI 60335-2-107:2012 traite de la sécurité des tondeuses à gazon robotisées à axe vertical alimentées par batterie, la tension assignée maximale de la batterie étant de 75 V c.c. La charge de la batterie s'effectue sur le secteur et/ou par énergie solaire. La présente Norme internationale ne s'applique pas aux machines non robotisées telles que les coupe-gazon, coupe-bordure de gazon, coupe-bordure, tondeuses autoportées ou tondeuses à gazon à conducteur à pied. La présente norme ne s'applique pas à la CEM et aux dangers environnementaux (à l'exception du bruit). La présente norme traite des phénomènes dangereux courants, présentés par les tondeuses à gazon robotisées alimentées par batterie, en ce qui concerne leur utilisation dans l'environnement immédiat de la maison ou pour des fins analogues. Les exigences relatives aux batteries sont couvertes par la CEI 62133. La présente norme internationale n'est pas applicable aux machines qui sont fabriquées avant la date de publication de ce document par la CEI.

Foreword
IS0 (the International Organization for Standardization) is a worldwide federation of
national standards bodies (IS0 member bodies). The work of preparing International
Standards is normally carried out through IS0 technical committees. Every 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, govern-
mental and non-governmental, in liaison with ISO, also take part in the work.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the IS0 Council. They are approved in accordance with IS0 procedures requiring at
least 75 % approval by the member bodies voting.
International Standard IS0 6940 was prepared by Technical Committee lSO/TC 38,
Textiles.
