What is BS EN 1998-4 - Earthquake resistance of silos

As a user of BS EN 60335-2-88 you can be ensured of safety requirements and their verification for the design and construction of requirements for humidifiers intended for use with heating

Live working. Phase comparators - Resistive type to be used for voltages from 1 kV to 36 kV a.c. LONG_TITLE and tests of lift components1 Scope This part of IEC 61481 is applicable to portable phase comparators of resistive type to be used on electrical systems for voltages from 1 kV a. c. to 36 kV a. c. and frequencies of 50 Hz and or 60 Hz. This standard is applicable to phase comparators of resistive type used in contact with the bare conductive parts to be compared: as a complete device including its insulating element or as a separate device, adaptable to an insulating stick
