Low-voltage controlgear. Part 2: Semiconductor contactors (solid state contactors)
Applies to semiconductor contactors intended for performing electrical operations by changing the state of electric circuits between on state and off state. The main circuit of the semiconductor contactors is intended to be connected to circuits the rated voltage of which does not exceed 1 000 V a.c. or 1 500 V d.c.
Basic environmental testing procedures - Part 2-46: Tests - Guidance to test Kd: Hydrogen sulphide t...
Gives guidance on the effect of hydrogen sulphide on electrical contacts and the significance of the test in IEC 68-2-43 on the behaviour of contacts exposed to such atmospheres.
The symbols system is intended for simplifying the preparation of diagrams of products in all branches of industry and is to be used in technical documentation as well as in technical and educational literature. This part contains the following: Motion of links of mechanisms, kinematic pairs, links and connections of their components, and N-bar linkages and their components.
Pipe connections, threaded to ISO 228/1, for plain end steel and other metal tubes in industrial app...
This second edition cacncels replaces the first edition (1973). Establishes a limited range of threads for connenction of tubes to machines or equipment and indicates the related outside diameters of the tubes. The outside diameters ranging from 4 mm up to and including 50 mm.
Aircraft — Joints for connecting crew members' regulator masks to oxygen sources
Gives joint lock dimensions for connecting these masks to sources in aircraft and helicopters. Joint dimensions standardization provides interchangeability with masks of various types. The basic dimensions and tolerances are shown in figures 1 and 2. Dimensions without tolerances can correspond to national standards. The lock halves shall be installed as shown in figures 1 and 2.
