Part 2:
Pipe prover design, calibration and operation
AMENDMENT 1
1) Clause 11.2: add a paragraph to the end of clause 11.2.
Prior to commencing the calibration, the system should be checked for leakage. If appropriate the operation
and leak checking of a four-way valve, or a seal leakage test of a piston prover, should be carried out. A
sphere displacer should be withdrawn safely for inspection (clause 13.3). When removed, a sphere can
be positioned on a clean dry and dirt-free surface in a location suitable for measurement to the required
accuracy. It can then be inspected for condition and inflation diameter measured (clause 6.5.4).
2) Clause 6.5.2: -Delete paras 8 to 11
3) Insert new clause 6.5.4
6.5.4  Sphere inspection and sizing
New and spheres which have been removed from a prover should be inspected in the same way. Removal of
a sphere and initial inspection should follow the guidance given in clause 13.3.
