Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. 1sO collaborates closely with the International Electrotechnical Commission (lEC)onallmattersofelectrotechnicalstandardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 9883 was prepared by Technical Committee ISO/TC 59, Building construction, Sub-Committee SC 6, Structure, envel- ope, internal subdivision Joints.

The tests are: a) for floors of joists and filler blocks: transverse dynamic bond test on finished floor, 5 joists and 4 rows of filler blocks, assembled as indicated; penetration resistance test of the finished floor, and b) for hollow slab floors: indentation/bending test on filler blocks (this test 5 slabs placed side by side and keyed with infill is designed to verify safety at the assembly stage). concrete.
