BS EN ISO 8330 standard is for Rubber and plastics hoses and hose assemblies Vocabulary. The committee responsible for this document is ISO/TC 45, Rubber and rubber products, Subcommittee SC 1, Rubber and plastics hoses and hose assemblies.
This International Standard defines terms used in the hose industry. This International Standard is divided into two subclauses, namely
— 2.1: hose terms, and
— 2.2: hose assembly terms.
2 Terms and definitions
2.1 Hose terms
strength of bond between cured rubber surfaces or between a cured rubber surface and a non-rubber surface or the strength of bond between two non-rubber (plastics) hose layers fused or glued together
angle of braid angle of lay
acute angle between any strand of the braid (2.1.17) and a line parallel to the axis of the hose
metal wire (usually manufactured from thin braided copper wires) incorporated in the hose wall (2.1.60)
in order to remove static electricity generated in the hose, and usually connected to the couplings (2.2.10)
of an assembly
hose (2.1.58) with a protective covering, generally applied as a braid (2.1.17) or helix (2.1.54), to minimize
protective covering over a hose, generally applied as a braid (2.1.17) or helix (2.1.54) to prevent
mechanical damage or to support the reinforcement (2.1.109) of a hose section
thin layer of film (polymeric) within the construction of the hose for preventing fluid or gas from
diffusing through the hose wall (2.1.60) to the atmosphere
radius of a bent section of hose measured to the innermost surface of the curved portion
<of a hose> forcing the hose out of a straight line into a curved position
load required to induce bending (2.1.8) around a specified radius and hence a measure of stiffness
smaller included angle between the warp (2.1.145)threads of a cloth and a diagonal line cutting across
the warp threads
cut made diagonally across a textile material at an angle less than 90° to the longitudinal axis
seam at which bias cut (2.1.11) fabrics are joined together
hollow space between layers in the hose wall (2.1.60), in which air or other gasses are entrapped
[SOURCE: ISO 1382]
round or flat wire helix embedded in the hose wall (2.1.60) to increase strength or to resist collapse
bonded hose construction
hose (2.1.58) with conductive metallic elements incorporated in the hose construction
Note 1 to entry: When determined in accordance with ISO 8031, the electrical resistance per unit length in the
case of hoses (lengths without couplings), or the electrical resistance between the fittings, in the case of hose
assemblies, does not exceed 10 2 Ω.
inside of a hose through which the material to be conveyed passes
continuous sleeve (2.2.38) of interwoven single or multiple strands of yarn (2.1.157) textile or wire
hose (2.1.58) in which the reinforcement has been applied as interwoven spiral strands
mark or symbol identifying the hose in accordance with the relevant International Standard, the mark
or symbol being embossed, inlaid or printed on the hose, coupling (2.2.10) or hose assembly
Note 1 to entry: In the relevant International Standard, a colour code may be included at the option of the
open mesh fabric (2.1.46) used to enhance the bond between a hose lining (2.1.78) or cover and its
carcass and to spread impact
Note 1 to entry: This element can also add reinforcement (2.1.109) to these components.
pressure at which rupture of the hose occurs when tested to the relevant International Standard
DEPRECATED: sealed end
hose end covered to protect its internal elements
fabric (2.1.46), cord and/or metal reinforcing section of a hose, as distinguished from the hose tube or
Note 1 to entry: See reinforcement (2.1.109).
appearance of the vulcanized cover produced by straight or spiral wrapping (2.1.123) used during
vulcanization (2.1.114) and subsequently removed
Note 1 to entry: See wrapper marks (2.1.156).
minimum diameter of coil to which a hose can be coiled without damage
softwall hose (2.1.120) which, when unpressurized internally, can be coiled or folded on itself
Note 1 to entry: See layflat hose (2.1.76).
hose (2.1.58) consisting of layers of non-vulcanized materials in sheeting form held together by two
metal or plastics spirals (one inside and one outside)
mixture of rubber or plastic and other materials that are combined to give the desired properties when
used in the manufacture of a hose
