In sections 6 7 and 8A of this Act the expression "relevant claim", in relation to an obligation, means a claim made by or on behalf of the creditor for implement or part-implement of the obligation, being a claim made—
and for the purposes of the said sections 6 7 and 8A the execution by or on behalf of the creditor in an obligation of any form of diligence directed to the enforcement of the obligation shall be deemed to be a relevant claim in relation to the obligation.
In section 8 of this Act the expression "relevant claim", in relation to a right, means a claim made in appropriate proceedings by or on behalf of the creditor to establish the right or to contest any claim to a right inconsistent therewith.
Where a relevant claim is made in relation to an obligation to which section 6 or 8A applies, the claim is to be treated for the purposes of that section as being made continuously until the claim is finally disposed of.
Where a claim which, in accordance with the foregoing provisions of this section, is a relevant claim for the purposes of section 6, 7 8 or 8A of this Act is made in an arbitration, the date when the arbitration begins shall be taken for those purposes to be the date of the making of the claim.
In this section the expression "appropriate proceedings" and, in relation to an arbitration, the expression "the date when the arbitration begins" have the same meanings as in section 4 of this Act.
