5、975 Glazing and Caulking i n Buildings (Reaffirmed: 1983) 1. Scope This Japanese Industrial Standard specifies the performances of the sealing compounds for buildings, hereinafter called as the “sealing compound“, in connection with their services such as the joint of building members, the sealing f
6、or surrounding of sashes, and the glazing of glass panes. Remarks 1. The standard covers the performances classified by the services of sealing material, using the sealed objects specified i n 6.11.2. In fact, however, because many kinds of the sealed objects are used under various circumferential c
7、onditions, it is preferable t o carry out tests taking into consideration the circumferential condition and the sealed objects. 2. In this standard, the units and numerical values i n 1 are i n accordance with the International System of Units (SI), and appended for reference only. 2. Definition The
8、 definitions of the terms used in this standard shall be as follows : sealing compounds material when applying which can be used at the jointing places of building members or parts for the purposes of watertightness and airtightness. The general term for the amorphous and sticky non-sag type The sea

17、 relative displacements are rather small. That for outdoors is that to be used for the place moistened by water in either outdoors or indoors, and that for indoors is that to be used for the place not moistened by water in indoors. The general use means the material to be used through whole year, th
18、e summer use means that for summer, spring, and autumn, and the winter use means that for winter, spring, and autumn. 3.2 Designation The designation of sealing compounds shall be designated as following manner, though unnecessary parts can be omitted.
