Rubber and plastics hoses - Determination of ultra-violet resistance under static conditions (ISO 8580:1987)

Provides a means of assessing the deterious effects of ultra-violet radiation under static conditions. specifies 3 methods: one for bore sizes up to 25 mm, tested on the hose itself; one for bore sizes greater than 25 mm, tested on a piece of the hose wall, and one for bore sizes greater than 25 mm, tested on a piece of the hose coating. The last method should only be used, if it is not possible to carry out the test in accordance with method two. 3 figures show the various test piece holders.

Tuyaux en caoutchouc et en plastique - Détermination de la résistance aux ultraviolets dans des conditions statiques (ISO 8580:1987)

La présente Norme internationale spécifie trois méthodes permettant de déterminer la résistance du revêtement extérieur à la lumière ultraviolette :
Méthode 1: pour des tuyaux ayant des diamètres inférieurs ou égaux à 25 mm, l'essai étant effectué sur le tuyau même.
Méthode 2 : pour des tuyaux ayant des diamètres supérieurs à 25 mm, l'essai étant effectué sur une éprouvette prélevée sur la paroi du tuyau.
Méthode 3 : pour des tuyaux ayant des diamètres supérieurs à 25 mm, l'essai étant effectué sur une éprouvette du revêtement externe du tuyau.
On doit utiliser normalement les méthodes 1 et 2. On n'utilisera la méthode 3 que s'il n'est pas possible d'effectuer l'essai conformément à la méthode 2.

Foreword ISO (the International Organization for Standardization) is a worldwide federation of national Standards bodies (ISO member bedies). The work of preparing International Standards is normally carried out through ISO technical committees. Esch 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 ISO Council. They are approved in accordance with ISO procedures requiring at least 75 % approval by the member bodies voting. International Standard ISO 8580 was prepared by Technical Committee ISO/TC 45, Rubber and rubber products. Users should note that all International Standards undergo revision from time to time and that any reference made herein to any other International Standard implies its latest edition, unless otherwise stated.

INTERNATIONAL STANDARD ISO 8580 : 1987 (E) Rubber and plastics hoses - Determination of ultra-violet resistance under static conditions 0 Introduction The test method described in this International Standard pro- vides a means of assessing the resistance of hoses to the deleterious effects of ultra-violet light under static conditions. NOTE - Most ultra-violet irridiation sources have a limited life after which the intensity of the radiation decreases. Care should be taken to ensure that the life of Operation of the fluorescent lamp is recorded and that the unit is rotated in accordance with ISO 4892, annex D, subclause 0.3.1, and is replaced after the useful life has expired. All apparatus placed in the test cabinet shall be fabricated from materials which do not absorb or react to ultra-violet light. 1 Scope and field of application 3.2 Test piece holder, as shown in figure 1, for Method 1. This International Standard specifies three methods for deter- mining the resistance of the outer cover of hoses to ultra-violet light : Method 1 : for bore sizes up to and including 25 mm, the test being carried out on the hose itself; Method 2 : for bore sizes greater than 25 mm, the test being carried out on a test piece from the hose Wall; Method 3 : for bore sizes greater than 25 mm, the test being carried out on a test piece from the hose cover. 3.3 Test piece holder, as shown in figure 2, for Method 2. 3.4 Test piece holder, as shown in figure 3, for Method 3. 4 Test pieces 4.1 Type of test piece 4.1.1 Method 1 Method 1 or 2 should normally be used. Method 3 should be used only if it is not possible to carry out the test in accordance with Method 2. The test piece shall consist of a Sample of hose. The length shall be calculated from the equation 2 References where ISO 291, Plastics - Standard a tmospheres for conditioning and tes ting.
