Gives recommended practice for the designation of package outlines and for the classification into forms of package outlines for semiconductor devices.
Refractory materials — Determination of thermal conductivity — Part 1: Hot-wire method (cross-array)
Belongs to a series of standard and specifies a hot-wire method for the determination of the thermal conductivety of refractory products. The method is applicable at temperatures not higher than 1250 °C and to materials whose thermal conductivity is less than 1,5 W/(m.k) and whose thermal diffusivity is less than 10-6 m2/s. Subject to the limits in 1.2, the method is applicable to powdered or…
Adhesives — Wood-to-wood adhesive bonds — Determination of shear strength by tensile loading
The method is intended for testing adhesives used in bonding wood to wood. Standard specimens are prepared from timber plies. The test specimens shall be of a two-ply or three-ply construction with notches as shown in a picture. The shear area is 20 mm x 25 mm. The adhesive shall be applied in accordance with the procedure recommended by the manufacturer of the adhesive. The mean tensile shear…
