tensile machine that:
 (a) is capable of generating a tensile force of 0.5 kN between the upper and lower platen; and
 (b) has an upper platen equipped with a tensile jaw capable of holding the stopper; and
 (c) has a bottom platen equipped with a jaw capable of securely holding the body of the hot water bottle without tearing any part of the hot water bottle.

3 Procedure

            Step 1 Ensure that the hot water bottle is at a temperature of (232)C.

            Step 2 Insert the stopper and tighten to a torque of (20.1) Nm.

            Step 3 Use a tensile machine to apply a force of 0.5 kN between the body of the hot water bottle and the stopper continuously for 5 minutes.

            Step 4A For a hot water bottle that is designed to be partly filled, follow the procedure set out in clause 1 of Part 1.1 of this Schedule and use water at a temperature of (232)C.

            Step 4B For a hot water bottle that is designed to be completely filled, follow the procedure set out in clause 2 of Part 1.1 of this Schedule and use water at a temperature of (232)C.

            Step 5 Use the test apparatus referred to in item 1 of Schedule 3 to apply a continuous compressive force of 0.90.09 kN to the body of the hot water bottle for 2 minutes30 seconds.

            Step 6 Inspect the hot water bottle for visible leakage and for any separation of the stopper.

Schedule 2 Seam test
(regulation 12)

1 Procedure

            Step 1 Cut from a hot water bottle 6 equally spaced strip test pieces of 12.5 mm wide with a minimum length of 115 mm at right angles to and around the seam.

            Step 2 Insert each test piece, 1 test piece at a time, in the jaws of a tensile machine and, using a rate of grip separation of 500 mm per minute, apply sufficient force to break the test pieces completely.

            Step 3 Record the maximum force required to break each test piece.

            Step 4 Report the median force required to break the test pieces.

Schedule 3 Determination of pressure resistance
(regulation 13)

1 Test apparatus

 (1) To comply with clause 2 of this Schedule, use test apparatus for which the upper and lower plate of the test apparatus must:
 (a) be smooth; and
 (b) be at least the size of the hot water bottle that is tested without contact from the neck of the hot water bottle; and
 (c) have smooth edges of approximately 3 mm radius; and
 (d) be free from sharp corners; and
 (e) be capable of applying a load of between 0 kN and 0.9 kN in not less
