5. METHOD FOR THE CALCULATION OF THE REPAIRABILITY INDEX OF SMARTPHONES AND SLATE TABLETS
The Repairability Index is an aggregated and normalised score, as a calculated value derived from six scoring parameters where:
—
S DD is the ‘Disassembly Depth’ score.
—
S F is the ‘Fasteners (type)’ score.
—
S T is the ‘Tools (type)’ score.
—
S SP is the ‘Spare Parts’ score.
—
S SU is the ‘Software Updates (duration)’ score.
—
S RI is the ‘Repair Information’ score.
The same scoring methodology shall apply to both smartphones and slate tablets. The Repairability Index (R) shall be calculated as follows:
R = (S DD *0,25)+(S F *0,15)+ (S T *0,15)+ (S SP *0,15)+(S SU *0,15)+(S RI *0,15)
The ‘Disassembly Depth’ (S DD ), ‘Fasteners (type)’ (S F ) and ‘Tools (type)’ (S T ) scores are based on the aggregation of the following priority part level scores:
—
BAT is the battery.
—
DA is the display assembly.
—
BC is the back cover or back cover assembly.
—
FFC is the front-facing camera assembly.
—
RFC is the rear-facing camera assembly.
—
EC is the external charging port.
—
BUT is the mechanical button.
—
MIC is the main microphone(s).
—
SPK is the speaker.
—
FM is the hinge assembly or the mechanical display folding mechanism.
If any of the priority parts listed above is present in a product more than once, only the one which delivers the lowest score shall be considered in the calculation of the ‘Disassembly Depth’ (S DD ), ‘Fasteners (type)’ (S F ) and ‘Tools (type)’ (S T ) scores. If a priority part is not present in the product, the highest point level for each score shall be considered for this part.
The ‘Disassembly Depth’ (S DD ) score shall be calculated as follows:
(a)
if the hinge assembly or the mechanical display folding mechanism are not present in the product, the following formula shall be used:
S DD = (DD BAT *0,30)+ (DD DA *0,30)+ (DD BC *0,10)+(DD FFC *0,05)+(DD RFC *0,05)+(DD EC *0,05)+(DD BUT *0,05)+(DD MIC *0,05)+(DD SPK *0,05)
(b)
if the hinge assembly or the mechanical display folding mechanism are present, the following formula shall be used:
S DD = (DD BAT *0,25)+ (DD DA *0,25)+ (DD BC *0,09)+(DD FFC *0,04)+(DD RFC *0,04)+(DD EC *0,04)+(DD BUT *0,04)+(DD MIC *0,04)+(DD SPK *0,04)+ (DD FM *0,17).
Disassembly Depth (DD) assessment at part level
The Disassembly Depth score (DD i ) for each priority part i (DD BAT ; DD DA , DD BC , DD FFC , DD RFC, DD EC, DD BUT , DD MIC , DD SPK, DD FM ) shall be calculated based on the number of steps required to remove a part from a product, without damaging the product. The counting of the steps for each part starts from the product fully assembled, with the charger disconnected and any SIM card installed. Points ranging from 1 to 5 are assigned as follows:
—
DD i ≤ 2 steps = 5 pt.
—
5 steps ≥ DD i > 2 steps = 4 pt.
—
10 steps ≥ DD i > 5 steps = 3 pt.
—
15 steps ≥ DD i > 10 steps = 2 pt.
—
DD i > 15 steps = 1 pt.
For the calculation of disassembly steps, the following rules shall apply:
—
the disassembly depth count is completed when the target part is separated and individually accessible.
—
where multiple tools need to be used simultaneously, the use of each tool counts as a separate step.
—
operations related to cleaning, removing traces or heating are counted as steps.
—
the disassembly depth shall be calculated on the basis of the repair and maintenance information, and of the description of the disassembly steps for each priority part given in the technical documentation;
—
where remote notification or authorisation of serial numbers is necessary for the full functionality of the spare part and the device, each of these actions is counted as five additional disassembly steps.
The
‘Fasteners (type)’
(S F ) score is calculated as follow:
(a)
for smartphones or slate tablets, except foldable ones, the following formula shall be used:
S F =(F BAT *0,30)+ (F DA *0,30)+ (F BC *0,10)+(F FFC *0,05)+(F RFC *0,05)+(F EC *0,05)+(F BUT *0,05)+(F MIC *0,05)+(F SPK *0,05)
(b)
for foldable smartphones or foldable slate tablets, the following formula shall be used:
S F =(F BAT *0,25)+ (F DA *0,25)+ (F BC *0,09)+(F FFC *0,04)+(F RFC *0,04)+(F EC *0,04)+(F BUT *0,04)+(F MIC *0,04)+(F SPK *0,04)+(F FM *0,17)
Fasteners (type) (F) assessment at part level:
The ‘Fasteners (type)’ scores (F i ) for each priority part i (F BAT , F DA , F BC , F FFC , F RFC, F EC, F BUT , F MIC , F SPK, F FM ) are assigned according to the level of removability and reusability of the fasteners used in the device assembly. Points ranging from 1 to 5 are assigned as follows:
—
Reusable Fasteners = 5 pt.
—
Resupplied Fasteners = 3 pt.
—
Removable Fasteners = 1 pt.
The assessment of the type of fasteners is based on the disassembly process to remove the specific priority part, starting from the previous priority part in disassembly sequence already removed.
In case different types of fasteners are encountered in the disassembly of a priority part, the worst score shall be considered.
The F i scores shall be calculated on the basis of the repair and maintenance information, and of the description of the fasteners for each priority part given in the technical documentation.
The
‘Tools (type)’
(S T ) score shall be calculated as follows:
(a)
for smartphones or slate tablets, except foldable ones, the following formula shall be used:
S T =(T BAT *0,30)+(T SCR *0,30)+(T BC *0,10)+(T FFC *0,05)+(T RFC *0,05)+(T EC *0,05)+(T BUT *0,05)+(T MIC *0,05)+(T SPK *0,05)
(b)
for foldable smartphones or foldable slate tablets, the following formula shall be used:
S T =(T BAT *0,25)+(T SCR *0,25)+(T BC *0,09)+(T FFC *0,04)+(T RFC *0,04)+(T EC *0,04)+(T BUT *0,04)+(T MIC *0,04)+(T SPK *0,04)+(T FM *0,17)
Tools (type) (T) assessment at part level
The ‘Tools (type)’ scores (T i ) for each priority part i (T BAT , T DA , T BC , T FFC , T RFC , T EC , T BUT , T MIC , T SPK and T FM ) are assigned according to the complexity and availability of the tools needed for its replacement. Points ranging from 1 to 5 are assigned as follows:
—
No tools = 5 pt;
—
Basic tools = 4 pt.
—
A set of tools that is supplied (or offered to be supplied at no additional cost) with the spare part = 3 pt.
—
A set of tools that is supplied (or offered to be supplied at no additional cost) with the product = 2 pt.
—
Commercially available tools = 1 pt.
The assessment of the type of tools is based on the disassembly process to remove the specific priority part, starting from the previous priority part in disassembly sequence already removed.
Where different types of tools are needed for the disassembly of a priority part, the lowest score shall be considered.
The T i scores shall be calculated on the basis of the repair and maintenance information, and of the description of the tools for each priority part given in the technical documentation.
Spare parts
The
‘Spare Parts’ (S SP ) score shall be calculated at product level as follows:
—
Spare parts for all priority parts are available to end users and professional repairers = 5 pt;
—
Spare parts for display assembly, battery, back cover (or back cover assembly) and cameras are available to end users and professional repairers; spare parts for all other parts are available to professional repairers = 4 pt;
—
Spare parts for display assembly, battery and back cover (or back cover assembly) are available to end users and professional repairers; spare parts for all other parts are available to professional repairers = 3 pt;
—
Spare parts for display assembly and battery are available to end users and professional repairers; spare parts for all other parts are available to professional repairers = 2 pt;
—
Spare parts for display assembly are available to end users and professional repairers; spare parts for all other parts are available to professional repairers = 1 pt;
—
Spare parts for the hinge assembly, mechanical display folding mechanism are to be available only in case of foldable smartphones.
Software Updates (duration)
The
‘Software Updates (duration)’ (S SU ) score shall be calculated at product level as follows:
—
Minimum guaranteed availability of security updates, corrective updates and functionality updates to the operating system for at least 7 years = 5 pt.
—
Minimum guaranteed availability of security updates, corrective updates and functionality updates to the operating system for 6 years = 3 pt.
—
Minimum guaranteed availability of security updates, corrective updates and functionality updates to the operating system for 5 years = 1 pt.
—
The above durations refer to years from the date of end of placement on the market of the product model.
Repair Information
The Repair Information (S RI ) score shall be calculated at product level as follows:
—
Public availability of repair and maintenance information, except electronic board diagrams, at no cost for end users and availability of repair and maintenance information, including electronic board diagrams, at no cost for professional repairers = 5 pt.
—
Availability of repair and maintenance information at no cost for professional repairers = 3 pt.
—
Availability of repair and maintenance information with a reasonable and proportionate fee for professional repairers = 1 pt.
—
A fee shall be considered reasonable if it does not discourage access by failing to take into account the extent to which the professional repairer uses the information.
