A Technical Working Area 17, cryogenic structural materials, has been organized in the Versailles Project on Advanced Materials and Standards (VAMAS) to promote the prestandardization program on material properties tests of glass fiber reinforced polymer (GFRP) composite materials and alloys at liquid helium temperature. A series of international interlaboratory comparisons of both compression and shear tests for composite material G-10 CR and tensile tests for solder were performed. Eleven research institutes from seven nations have participated in this project. In compression and shear tests on the composite material, the amount of data scatter increased in lower temperature. The scatter of the compression strength decreased by the limitation of specimen geometry. The scatter of shear strength was small among the same testing procedure. The scatter of solder among the institutes are much due to the lower strength of the material.
