IEC 60684 Flexible Insulating Couplers

The International Electrotechnical Commission (IEC) is a standards body that prepares and publishes international standards for all electrical, electronic and related technologies, collectively known as electrotechnology. The International Standards Organization (ISO) develops standards in all areas except electrical and electronic engineering standards, which are the responsibility of the International Electrotechnical Commission (IEC). The term ISO/IEC refers to a standard governed by both ISO and IEC.

The IEC 60684 set of standards, developed by the International Electrotechnical Commission (IEC), basically consists of the following three parts:

• EN 60684-1 Flexible insulating sleeves - Part 1: Descriptions and general rules
• EN 60684-2 Flexible insulating sleeves - Part 2: Test methods
• EN IEC 60684-3 Flexible insulating sleeves - Part 3: Specific rules for each sleeve type

Of these, the EN IEC 60684-3 standard is the most comprehensive and there are many sub-standards under which each type of coupling is included. Here are a few of them:

• Uncoated, expandable braided ethylene chlorotrifluoroethylene (e-CTFE) textile sleeve
• Extruded PTFE sleeves
• Extruded silicone sleeve
• Heat shrinkable semi-flexible polyvinylidene fluoride sleeve, flame retardant, liquid resistant, shrink ratio 2:1
• heat shrinkable PTFE sleeve
• Braided, uncoated, glass textile fiber sleeve
• Lightly impregnated polyethylene terephthalate textile sleeve
• Silicone elastomer coated glass textile sleeve
• Acrylic based coated glass textile sleeve
• Acrylic based coated polyethylene terephthalate textile sleeve
• Extruded polyolefin, flame retardant, limited fire hazard sleeve
• Extruded polychloroprene - General purpose

• Flame retardant fire hazard limited sleeve with extruded polyolefin
• Heat shrinkable polyolefin sleeve, double wall, flame retardant
• Extruded fluorosilicone sleeve - General purpose

• Heat shrinkable fluoroelastomer sleeve, flame retardant, liquid resistant shrink ratio 2:1
• PVC coated glass textile sleeve
• Polyurethane-based coated glass textile sleeve (pur)
• Expandable braided polyethylene terephthalate textile sleeve
• Flame retardant, fluid resistant, heat shrinkable semi-rigid polyvinylidene fluoride sleeve, shrinkage ratio 2:1

The IEC 60684 series of standards provides test methods for a variety of sleeving, including heat shrink tubing, primarily designed to insulate electrical conductors and connections of electrical apparatus. These test methods are designed to control the quality of the sleeve, but are considered to not fully determine the suitability of the sleeve for impregnation or encapsulation processes or other special applications. Where necessary, these test methods should be supported by compatibility tests.

Our organization also provides flexible insulating sleeves testing services within the scope of IEC 60684 standard, with its trained and expert staff and advanced technological equipment, among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors.
