or chain if a chain block, passing around its sheave; and
(b) a mass of 4 times the SWL must be secured to the head fitting of the fitting and lifted from the ground; and
(c) for a single sheave block with a becket — the test must be done with a part of the supporting wire secured to the becket to avoid overstressing the sheave or pin.
      (3) However, the test may be carried out in another way if the same stress is applied to the block.
      (4) For testing a multiple sheave block:
(a) the proof load must be at least the load mentioned in Table 3 for the block; and
(b) it must be reeved in its normal operating condition; and
(c)  the proof load must be applied to the head fitting of the block to be tested.
Note   Testing a multiple sheave block usually requires the use of a second block or an equivalent arrangement for the rope.

 Table 3
SWL of block (tonnes)  Proof load
≤ 25                   SWL × 2.0
> 25 and  ≤ 160        (SWL × 0.933) + 27 tonnes
> 160                  SWL × 1.1

      (5) If a chain, ring, hook, shackle, swivel, connecting plate or overhauling weight is tested, the proof load must be at least the load mentioned in Table 4 for it.

 Table 4
SWL of article (tonnes)  Proof load
≤ 25                     SWL × 2
> 25                     (SWL × 1.22) + 20 tonnes

      (6) For a hand operated block used with pitched chains, its associated chains and any permanently attached rings, hooks, swivels or associated shackles must be tested:
(a) with a proof load of at least 1.5 times SWL; or
(b) with the articles mentioned in subclause (1), (2) or (5).
      (7) After testing an article mentioned in subclause (1), (4), (5) or (6), the article must be examined by a competent person for damage or permanent deformities.
Examples of other damage or permanent deformities
a crack or flaw to a block, the head fitting, sheave or sheaves, axle, crosshead, becket or other part.

8 Trays, crates, tubs, grabs, scrap bins, other receptacles for loading or unloading cargo
      (1) If a tray, crate, tub, grab or other receptacle for use in loading or unloading cargo, other than a container or returnable cargo unit mentioned in clause 14 or 15, is tested, the proof load must be:
(a) at least the load mentioned in Table 5; and
(b) wholly supported by the bottom surface of the receptacle.
