3 Terms and definitions
For the purposes of this document, the termns and definitions given in EN ISO 8330 and the following apply.
3.1 electrically bonded hose/hose assembly
hose/hose assembly that uses a metallic wire connection to conduct static electricit
3.2 electrically conductive hose/hose assembly
hose/hose assembly that is capable of conducting static electrical charges, using a conductive rubber layer, without the use of a metallic wire
3.3
electrically discontinuous hose/hose assembly
hose /hose assembly that incorporates a metallic wire connection to one end coupling of the assembly only or is electrically insulated from both end-couplings
5.2 Hose assemblies
Hose assemblies shall incorporate metallic couplings attached to the hose by the assembler or built in by the manufacturer. In order to produce the required electrical properties, the couplings should be attached in accordance with Clause 8.
Chlorinated materials shall not be used in contact with any stainless steel materials.
6 Dimensions
6.1 Nominal bore, internal diameters, outside diameters, tolerances, and minimum bend radius.
For hoses without built-in couplings, and when measured in accordance with method A of EN ISO 4671, the internal diameter and outside diameter and their tolerances shall conform to Table 1 or Table 2 depending on the type.
For hoses with built-in couplings, the outside diameters in Tables 1 and 2 do not apply.
When tested by the method described in EN IS0 10619-1, the value of the minimum bend radius shall be as given in Table 1 or Table 2, depending on the type.
