ISO 4195:2007

Conveyor belts with heat-resistant rubber covers — Heat resistance of covers — Requirements and test methods

ISO 4195:2007 specifies requirements and test methods for the relative level of heat resistance of conveyor belt covers made of rubber. It gives the variations of hardness, elongation at break and tensile strength after exposure to heat. It is applicable only to those conveyor belts having a cover thickness greater than or equal to 4 mm. It is not suitable or valid for light conveyor belts as described in ISO 21183-1.

Courroies transporteuses avec revêtements caoutchouc résistant à la chaleur — Résistance à la chaleur des revêtements — Exigences et méthodes d'essai

L'ISO 4195:2007 spécifie les exigences et les méthodes d'essai pour le niveau relatif de résistance à la chaleur des revêtements en caoutchouc de courroies transporteuses. Elle spécifie les variations admissibles de dureté, d'allongement à la rupture et de résistance à la traction après exposition à la chaleur. Elle s'applique uniquement aux courroies transporteuses ayant un revêtement d'une épaisseur égale ou supérieure à 4 mm.

Naprave za kontinuirni transport - Trakovi tračnih transporterjev s toplotno odporno gumijasto prevleko - Toplotna odpornost prevleke - Zahteve in preskusne metode

Ta mednarodni standard določa zahteve in preskusne metode za relativno raven toplotne odpornosti gumijastih prevlek trakov tračnih transporterjev. Standard določa dovoljene razlike v trdoti, raztezku pri zlomu in natezni trdnosti po izpostavljenosti toploti. Uporablja se samo za trake tračnih transporterjev z debelino prevleke najmanj 4 mm. Standard se ne uporablja oziroma ni veljaven za lahke trakove tračnih transporterjev iz standarda ISO 21183-1[1].

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 4195 was prepared by Technical Committee ISO/TC 41, Pulleys and belts (including veebelts),
Subcommittee SC 3, Conveyor belts.
This first edition of ISO 4195 cancels and replaces ISO 4195-1:1987 and ISO 4195-2:1988, of which it

Avant-propos
L'ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes nationaux de
normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est en général confiée
aux comités techniques de l'ISO. Chaque comité membre intéressé par une étude a le droit de faire partie du
comité technique créé à cet effet. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec l'ISO participent également aux travaux. L'ISO collabore étroitement avec
la Commission électrotechnique internationale (CEI) en ce qui concerne la normalisation électrotechnique.
Les Normes internationales sont rédigées conformément aux règles données dans les Directives ISO/CEI,
Partie 2.
La tâche principale des comités techniques est d'élaborer les Normes internationales. Les projets de Normes
internationales adoptés par les comités techniques sont soumis aux comités membres pour vote. Leur
publication comme Normes internationales requiert l'approbation de 75 % au moins des comités membres
votants.
L'attention est appelée sur le fait que certains des éléments du présent document peuvent faire l'objet de
droits de propriété intellectuelle ou de droits analogues. L'ISO ne saurait être tenue pour responsable de ne
pas avoir identifié de tels droits de propriété et averti de leur existence.
L'ISO 4195 a été élaborée par le comité technique ISO/TC 41, Poulies et courroies (y compris les courroies
trapézoïdales), sous-comité SC 3, Courroies transporteuses.
Cette première édition annule et remplace l’ISO 4195-1:1987 et l’ISO 4195-2:1988, qui ont fait l'objet d'une
révision technique.
