11、e in this Standard, constitute provisions of this Standard. If the indication of the year of coming into effect (or the year of issue) is given to these referred stan- dards, only the edition of indicated year constitutes the provision of this Standard, but the revision and amendment made thereafter
12、 are not applied. The normative references without the indication of the year of coming into effect (or the year of issue) shall apply limiting only to the most recent edition (including the amendment).

This is only the change in number and the contents remain unchanged. 3 Definitions a) pressure-sensitive adhesive tapes Tapes whose one side is coated with an adhesive which maintain adhesiveness permanently at room temperature. They are adhered on various types of differe
15、nt surfaces by making them in contact with the surface then slightly pressurizing them so that the activation by means of water, solvent or heat is not required. 4 Classification and designation Classification and designation of tapes shall be as stated below. -,-,- STDOJIS C 233b-ENGL 1999 4933608

37、ill be firmly positioned in the correct direction during storage. 7.4 Caution for handling Because the quality of tapes is liable to be affected by the temperature, pressure, etc., it is desirable to keep the following items during the storage and handling: a) b) To avoid places with direct sunlight
38、 and high temperature. To avoid loading the packages lateralized for the purpose of prevention of de- formation.
