適用范圍： This document belongs to the suite of European Standards EN 14399 and is designed to be read in conjunction with EN 14399-1 for: general requirements; testing for conformity evaluation; evaluation of conformity; -- regulatory marking; for assemblies of high-strength structural countersunk bolts and nuts of system HR suitable for preloaded joints with thread sizes M12 to M36 and bolt property classes 8.8 and 10.9 and EN 14399-2 for suitability testing. This document gives requirements for: -- dimensions; -- associated washer(s) according to EN 14399-5 or to EN 14399-6; -- performance and suitability tests; for assemblies with thread sizes M12 to M36 and bolt property classes 8.8 and 10.9. Countersunk bolt and nut assemblies to this document have been designed to allow preloading of at least 0,7jub x .,Is1) according to EN 1993-1-8 (Eurocode 3) and to obtain ductility predominantly by elongation of the bolt. For this purpose the components have the following characteristics: -- nut height according to style 1 (see EN ISO 4032), -- thread length of the bolt according to ISO 888.
