IEC 61479 pdf download – Travaux sous tension – Protecteurs de conducteurs flexibles en matériau isolant
1 Scope
This International Standard is applicable to flexible insulating covers (line hoses) for theprotection of workers from accidental contact with live or earthed electrical conductors and forthe avoidance of short circuits during live working.
1.1Classes
Five classes of conductor covers，differing in electrical characteristics， are provided anddesignated as class 0, class 1, class 2, class 3, and class 4.
1.2Categories
Six categories of conductor covers differing in composition and properties are provided:category A – acid resistant,category H – oil resistant,category C – formulated for extreme lowtemperature environments，category w – formulated for extreme high temperature environ-ments, category Z- ozone resistant, and category P – formulated for humid environment.
NOTE Types ll and lll maferial of ASTM D-1050 would be cafegory z.
1.3Styles
Various styles of conductor covers,differing in construction characteristics are available andsix of these are designated as style A, styie B, style C, style D, style E, (see figure 1), andstyle F.

3Definitions
Pour les besoins de la présente Norme internationale, les définitions suivantes s’appliquent.
3.1
protecteur
protecteur rigide ou souple realisé en materiau isolant utilise pour recouvrir les parties soustension ou hors tension ou les parties adjacentes mises a la terre de maniere a prevenir toutcontact avec ces parties
NOTE Un protecteur est generalement conqu pour procurer un niveau d’isolation requis qui lui permet de fournirune protection uniquement lorsqu’un travalleur entre par inadvertance en contact avec le protecteur et ceseulement pendant une courte duree.

3 Definitions
For the purpose of this International Standard, the following definitions apply.
3.1
protective cover
rigid or flexible cover made of insulating material used to cover energized and/or dead partsand/or adjacent earthed (grounded) parts in order to prevent contact
NOTE A protective cover is generally designed to provide a required insulation level which makes it able toprovide protection only when a worker inadvertently comes into contact with the protective cover and for only ashort duration.
