Single-capped fluorescent lamps - Safety specifications
1 Scope
This document specifies the safety requirements for single-capped fluorescent lamps for general lighting purposes of all groups having caps according to Table 1 .
It also specifies the method a manufacturer should use to show compliance with the requirements of this standard on the basis of whole production appraisal in association with his test records on finished products. This method can also be applied for certification purposes. Details of a batch test procedure which can be used to make limited assessment of batches are also given in this standard.
This part of the standard covers photobiological safety according to IEC 62471.
Blue light and infrared hazards are below the level which requires marking.
Note: Compliance with this standard concerns only safety criteria and does not take into account the performance of single-capped fluorescent lamps for general lighting purposes with respect to luminous flux, colour, starting and operational characteristics. For this information, readers are referred to IEC 60901.
It may be expected that lamps which comply with this standard will operate safely at supply voltages between 90 % and 110 % of rated supply voltage of the used ballast and when operated with a ballast complying with IEC 61347-2-3 or IEC 61347-2-8 with a starting device complying with IEC 60155 (if applicable) and in a luminaire complying with IEC 60598-1.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
single-capped fluorescent lamp
low-pressure mercury discharge lamp having a single cap in which most of the light from the lamp is emitted by a layer of fluorescent material excited by the ultraviolet radiation from the discharge
3.2
group
lamps having the same electrical and cathode characteristics, the same physical dimensions and the same starting method
3.3
type
lamps of the same group having the same photometric and colour characteristics
3.4
family
lamp groups which are distinguished by common features of materials, components, tube diameter and/or method of processing
3.5
nominal value
approximate quantity value used to designate or identify a lamp
3.6
rated value
quantity value for a characteristic of a lamp for specified operating conditions
Note: The value and the conditions are specified in this standard, or assigned by the manufacturer or responsible vendor.
3.7
design test
test made on a sample for the purpose of checking compliance of the design of a family (3.4), group or a number of groups (3.2) with the requirements of the relevant clause
3.8
periodic test
test, or series of tests, repeated at intervals in order to check that a product does not deviate in certain respects from the given design
3.9
running test
test repeated at frequent intervals to provide data for assessment
3.10
batch
all lamps of one family (3.4) and/or group (3.2) and identified as such and put forward at one time for test or checking compliance
3.11
whole production
production during a period of twelve months of all types of lamps within the scope of this standard and nominated in a list of the manufacturer for inclusion in the certificate
3.12
SoS value
abbreviation for the “sum of the squares” (Sum of the Squares, SoS) of the two currents through the two lead wires at a lamp electrode. The currents are measured as r.m.s. values. The lead current at one electrode coil, which gets the higher r.m.s. current value is called ILH (“lead high”), the lead current with the lower r.m.s. value is called ILL (“lead low”). The values of the two currents have to be squared and added (SoS = ILH2 + ILL2).
