Performance standards in building — Performance test for precast concrete floors — Behaviour under n...
Defines test procedures for determining the mechanical performance of precast concrete floors made of a single piece, or made up of precast joists (reinforced concrete or precast concrete) completed with filler blocks and concrete poured in situ. The parameters measured are: the maximum load, which does not result in collapse, the instantaneous and deferred deformations under imposed load, and…

The test procedures defined are: transverse dynamic bond test on finished floors, penetration resistance test of the finished floor, and indentation/bending test on filler blocks (this test is designed to verify safety at the assembly stage). Applies to all kinds of precast concrete floors and to components thereof.
Information technology — Microprocessor systems — VICbus — Inter-crate cable bus
The objectives are to provide a standard cable bus for the interconnection of multiple devices, both backplane bus systems, such as the IEC 821 VMEbus, and stand-alone apparatus; to specify the electrical characteristics of the cable bus; to specify the protocols that precisely define the interaction between devices connected to the VICbus; to specify the mechanisms necessary to construct fault-…
Specifies the characteristics (dimensions, specifications, designation) for screws having threads from M1,6 up to and including M24 and of product grade A. If, in special cases, specifications other than those listed are required, they should be selected from existing international standards, e.g., ISO 261, ISO 888, ISO 898-5 and ISO 965-2. Annex A describes gauging of hexagon socket.
