To determine any dangerous burning properties and splint breakage during striking.
Clean sheet of white paper and stopwatch which is accurate to 1 s.
Select sufficient match boxes from the conditioned sample to provide a test specimen of not less than 200 matches, taking no more than 5 matches from each box.
Place the sheet of white paper on the surface over which the matches are to be struck.
Using the method of striking matches in 4.3.3.2, strike all matches, observe and record any of the following defects:
NOTE Splints which break during striking should be replaced by the same number of matches to ensure a specimen of 200 matches for the test burning property.
For book matches, ensure that the match is struck in the orientation most likely to cause failure.
To determine if splints have been properly treated to prevent afterglow.
10Perforated metal plate (see Figure 2).
Figure 2 — Perforated metal plate
Insert the bases of 100 matches, randomly selected from the conditioned samples, into the holes of the metal plate.
Ignite the taper and apply the flame to the outside row of the matches.
Tilt the plate so as to ignite all the matches as quickly as possible.
Allow the splints to burn completely until the flame dies out.
Start the stopwatch simultaneously and after 3 s, record any afterglow, ignoring any pinpoint glow immediately beneath the head.
11To determine whether matches will ignite spontaneously in a heated atmosphere.
Metal plate to hold matches vertically 10 mm apart and an air circulating oven.
Insert 20 matches randomly selected in the metal plate with heads pointing upwards.
For book matches, a length of comb containing 12 matches shall be suitably supported at its base.
Place in the oven maintained at 120 °C ± 2 °C and leave for 15 min.
After the time has elapsed, remove from the oven and record the number of matches, if any, which ignited.
To determine the efficiency of the striking surface and the likelihood of ignition during striking.
Select four full match boxes from the conditioned sample.
Using the method of striking matches in 4.3.3.2, strike all the matches in each box on only one side of the box.
Observe and record whether all the matches were successfully ignited. Also report whether any of the friction surfaces ignited during striking.
To assess the strength of splints supplied for the production of matches.
Using a suitable mechanical strength tester based on the falling weight method, randomly select 100 matches from the batch and subject to an impact of 12 mJ.
Observe and record the number of splints which fracture or break during this procedure.
12To assess flame height achieved during the burning of match splints.
Hold the match in position by inserting the stem 5 mm into a metal tube clamped in the horizontal position.
Position the match 25 mm ± 3 mm away from a vertical plane mirrored plate scribed with two horizontal lines separated by 10 mm.
Adjust the height of the plate so that the upper surface of the match splint, its mirror image and the lower line are all coincident.
Ignite the match by touching the tip of the head with a heated soldering iron. At the same time start a stop watch.
Observe the flame carefully during the period between 3 s and 10 s from ignition and record whether the flame does not exceed 10 mm in height. This is indicated if the tip of the flame does not cross the upper of the two lines scribed on the mirrored plate.
At all times during the observation of the flame ensure that the stem, its mirror image and the bottom line remain coincident in order to prevent parallax errors.
Record whether the flame does not remain alight for 10 s. If the match is less than 40 mm in length, record whether the flame does not remain alight for 6 s.
NOTE Alternative arrangements for measurement of flame height are acceptable, provided adequate arrangements to prevent parallax errors are incorporated.
