(3) After completion of heating time of (2) [in the grade 3 quick heating – impact and drop
combination test, after completion of heating time of (1)] draw out the specimen from the heating
furnace, by using a circular hook for suspending down of specimen upper part draw up to the height
of 4 m, and thereafter drop on the ordinary bricks (refer to Fig. 11) laden flatly by the thickness of
one sheet on the concrete base.
Let the time since drawing out from the heating furnace until dropping be 10 min.
Further, in the case of grade 3 quick heating – impact and drop combination test, after dropping
leave as it is for 30 min, and then examine the change in co lour, deterioration and whether it is possible to read
or not the newspaper entered in storing part by opening the door, drawer or sliding door.

(4) Further, place the specimen so cooled that the works is possible with reversing in a heating furnace,
again make it along the standard temperature curve of 8.5.3 and again heat for test item division
shown in Table 9 until reaching to the heating time specified in Table 13.

(5) In the case of heating of (2) and (4), the permissible error of heating temperature relative to the
standard temperature curve shall be + - 10%.
(6) After completion of heating time specified in (4), immediately take out the specimen from the heating
furnace, discharge water to cool the specimen, open the door, drawer or sliding door and examine the
change in colour, deterioration and whether it is possible to read or not for the newspaper entered in
the storing part.
8.5.7
Number of Times of Fire-Resistance Test and Report of Results of Fire-Resistance Test
(1) Number of times of tests of 8.5.5 and 8.5.6 shall be respectively one time.
(2) On the report of the results of fire-resistance test, the following matters shall be described:
(a) Classification and commercial name of fire-resistive container
(b) Using materials (name of fire-resistive material, specific gravity, moisture content, composition of
materials, filling day, etc.)
(c) Shape and dimensions of specimen
(d) Test matters

(j) Type of heat source of heating furnace
(k) Test date
(l) Test organ and name f person in duty of test
9. Inspection
