within 0.5〜1.0, without exceeding the number of verification scale interval originally approved;

(3) Where the range of tare decreases;

(4) Where a weighing instrument is used with the same circuit board as that of a type-approved

pricing weighing instrument but without the pricing element and the pricing display;

(5) Where the type, color or size of display tube or display component is changed, or the

arrangement of the elements on the panel is changed, without changing the driving electronic

circuit;

(6) Where the pattern of buttons or their arrangement on the panel is changed without changing the

driving electronic circuit;

(7) Where any button operating function is added or reduced without changing the effect of

weighing or pricing, nor changing the driving electronic circuit;

(8) Where the size of the load receptor is changed within 20% of the original size approved;

(9) Where any active or passive component is replaced by another with the same or higher

performance (only applicable to the performance that is easy to confirm on the manual or

specification sheet);

(10) Where the specification of battery is changed;

(11) Where an internal jump wire is added with changing the inter-crossing only;

(12) Where a few passive components are added to a non-weighing circuit or I/O circuit to prolong

its service life;

(13) Where the appearance of the base is changed;

(14) Where the arrangement of external texts or marks is changed; or

(15) Where the foot pad of the instrument is changed.
 

6. Under any of the following circumstances, application for series type approval or approbation

shall be filed, after complete the necessary performance tests listed as below, for type-approved

electronic non-automatic weighing instruments:

(1) Where the number of verification scale interval is out of the original range approved, the

weighing performance, discrimination, repeatability, eccentricity, zero return, creep, tilting, tare,

temperature, endurance and other relevant items should be tested.

(2) Where the weighing circuit, the control program, or the control circuit of display is changed, the

weighing performance, voltage variation, short time power reduction, electrical burst, electrostatic

discharge, and immunity to radiated electromagnetic field and other relevant items should be tested.

(3) Where the load cell or the structural connector (aluminum reinforcement, aluminum tray) of load

cell is changed, the weighing performance, discrimination, repeatability, eccentricity, zero return,

creep, temperature, tilting, tare, endurance and other relevant items should be tested.

(4) Where the compensation method of power supply circuit is changed, the voltage variation, short

time power reduction, electrical burst, and other relevant items should be tested.

(5) Where the size of load receptor is changed by more than 士20 % of the original size approved or

the shape of the support is changed, the weighing performance, eccentricity, tilting and other

relevant items should be tested.

(6) Where the approved material of the structure or the load receptor changed, the electrical burst,

electrostatic discharge, immunity to radiated electromagnetic field and other relevant items should

be tested.

(7) Where the range of tare originally approved is increased, the tare test should be conducted.

(8) Where the load receptor to be higher or the connecting parts(aluminum reinforcement or

aluminum receptor) of load cell changed eccentricity, tilting and other relevant items should be

tested.

(9) Where the A/D converter and the circumference are changed without changing load cell, the

weighing performance, temperature, damp heat, voltage variation, immunity to radiated

electromagnetic field and other relevant items should be tested.

(10) Where the circuit layout is changed without relative with the electronic components mentioned

in other items, the electrostatic discharge, immunity to radiated electromagnetic field and other

relevant items should be tested.
