ISO 21254-1:2011 defines terms used in conjunction with, and the general principles of, test methods for determining the laser-induced damage threshold and for the assurance of optical laser components subjected to laser radiation.
Space systems — Stable operation requirements for satellite attitude and orbit control system
Satellite attitude and orbit control system (AOCS) is responsible for completing the attitude and orbit control of the satellite. It is essential for ensuring the basic functions and stable operation of the satellite.
This standard specifies the definition of on-orbit stable operation of the satellite AOCS. According to the influencing factors of the satellite on-orbit stable operation, it…
Space systems — Launch window estimation and collision avoidance
This international standard (NWIP) provides details and associated requirements for tools, techniques, and analyses required to identify launch windows and associated closure times for Safety Launch Collision Avoidance (LCOLA) and (in an informative annex) Mission Assurance LCOLA. The methods evaluate the estimated close approach distances and corresponding collision probabilities between the…

Glass in building — Determination of the emissivity
This document specifies a procedure for determining the emissivity at room temperature of the surfaces of glass and coated glass.
The emissivity is necessary for taking into account heat transfer by radiation from surfaces at the standard temperature of 283 K in the determination of the U value and of the total solar transmittance of glazing.
The procedure, being based on spectrophotometric…
