Annex I

Annex II

Appendix III

Requirements fixed cordless emergency which according to § 7 will be installed on devices to be able to operate in areas with temperatures significantly below 0 ° C.

1.
According to § 12 of the Regulations of 4 September 1987 No.. 856 concerning construction of mobile units, should mobile units be equipped with emergency lighting. According to these regulations § 7 the facilities that will be able to operate in areas with temperature significantly below 0 ° C, to provide proof that the equipment can operate safely in such conditions.

2.
In addition to international regulations and requirements for regular emergency lighting shall be emergency lighting for use in areas with temperatures below -10 ° C satisfy the following requirements:

2.1
Emergency to be used for operation in the area where the monthly mean temperature (see Appendix) can be as low as -10 ° C, or diurnal mean temperature can be as low as -20 ° C, (including battery and fittings) will be tested and work for ambient temperature of from -20 ° C to 55 ° C.

2.2

Emergency to be used for operations in the area of ​​lower temperature than those referred to in paragraph. 1 above, (including battery and fittings) will be tested and work for an ambient temperature from -30 ° C to +55 ° C.

2.3
For emergency lighting that will be used for average temperatures below -30 ° C, special assessments be applied in each case.

2.4
Emergency to be used in heated rooms or in temperatures down to -10 ° C, does not particularly cold tested, assuming satisfactory cold properties are documented by the supplier.

Amendment to Appendix III

Calculations of temperatures. Monthly mean temperature is calculated by the formula:
M = n - k (n - Min)
where n = means of observations at. (8:00) - 7:00 to 1:00 p.m. - 19:00 (MET)
MET = meteorologic European Time.
K = a factor that varies with the seasons and from station to station.
My = the mean minimum temperature for each day. One month
temperature extremes applies to the clock counting from kl. 10:00 PM. 19:00.
Calculation of days mean:
Td = T07 + T19 + Tmin. + Tmax. / 4
Td = Hour average temperature.
T07 = temperature measured at. 7:00
T19 = temperature measured at. 19.00
Tmin. = Around the clock minimum.
TMax. = Around the clock maximum temperature.
