PD IEC/TR 62331 outlines the method of measurement of the magnetic properties of magnetically hard materials that have been specified in IEC 60404-5 for closed magnetic circuits and in IEC 60404-7 for open magnetic circuits

It defines the conventional useful lifetime

Adding “Capacity after storage” (from the date of manufacture) (Annex B)

together with the state variables of temperature and density

the phase-sensitive method is more affected by the electrical properties of the coating materials

Glass for Glazing also prevents air leaks and protects the end user from outside particles like dust

poly-glycols)

particle-particle interactions and multiple light scattering can become dominant and may result in apparent particle sizes that differ between concentrated and dilute suspensions

NOTE This information helps AMB system users better to understand the selection process and implications of transition to AMB technology

for example for use in field work

• viewing angle of half-contrast
