Specifies requirements for metal-banded flexible couplings used in low-pressure pipeline systems that convey water, waste water or stormwater. Acceptance criteria for defined imperfections are given for sleeves and adaptor bushes. It includes appendices which set out test methods.

Scope

This Standard specifies requirements for metal-banded flexible couplings (referred to in this Standard as flexible couplings) either with or without metal shear rings to be used in below or above ground low-pressure pipeline systems which convey water, waste water or stormwater.
The Standard applies to flexible couplings designed for jointed items having the same or similar nominal internal diameters, made from the same or different materials. It does not apply to adaptor flexible couplings designed for jointed items having significantly different diameters.
Spigot and socket joints with elastomeric seals are not covered by this Standard.
NOTES:
1 Flexible couplings with metal shear rings are preferred for applications subject to the effect of soil loads and any superimposed loads, including repairs and post-construction connections to existing pipeline systems.
2 Elastomeric joint seals for waterworks purposes are specified in AS 1646.
3 Guidelines to purchasers on information to be specified at the time of enquiry or order are given in Appendix A.
