IP RATING
The IP (ingress protection) rating corresponds to the instrument's degree
of protection against penetration by solid bodies (1st digit) and against
penetration by water (2nd digit). The higher the rating, the greater the
protection. A product without protection corresponds to a rating of IP00
(minimum rating), whereas a product totally protected against solid bodies
and liquids is rated IP68 (maximum rating).
IEC 61010
This international standard defines the safety rules for electrical measurement,
control and laboratory instruments. It guarantees that the
instruments' design and construction ensure protection of users and their
environment against: electric shocks, burns, mechanical hazards, spread
of fire from the instruments, excessive temperatures, etc.
For some types of instruments, this standard is completed by special
prescriptions.
Example: the IEC 61010-2-010 standard specifies the special requirements
for laboratory equipment used for heating materials.
IEC 61557
This international standard specifies the electrical safety characteristics
of 1,000 Vac and 1,500 Vdc low-voltage transmision networks. It defines
all the requirements for combined performance measurement and monitoring
systems which measure and monitor the electrical parameters in
electrical transmision networks. These requirements also define the performance
levels in single-phase or three-phase AC or DC networks with
rated voltages less than or equal to 1,000 Vac or 1,500 Vdc .
NF C 15-100
This is the official safety standard concerning the protection of low voltage
electrical installations, the protection of people and the ease of managing,
operating and upgrading the installation. Installations in housing
(house or apartment) must comply with this standard. In particular, NF
C 15-100 defines the protective systems, RCD circuit-breakers, wiring,
number and type of lighting counts and number of power outlets in each
type of room (bathroom, kitchen...), etc.
