7 Information provided by manufacturer
7.1 General
NIS shall be accompanied by adequate information on safe use, considering the training

identification. Instructions for use shall be included in the user packaging.

7.2.1 General
Any markings provided on user packaging for safe use of NIS shall be legible. It shall
be inspected by visual inspection (normal or corrected vision observation) under the
conditions of ambient lighting (215±20) lx and viewing distance of 40cm~70cm.

The marking on the NIS includes at least the following information/content:
a) Manufacturer's name or trademark;
NOTE: The trademark may be enough to identify the manufacturer.
b) Details required by the user to identify the NIS;
c) Batch code, batch number or serial number, beginning with the corresponding
symbol.
7.2.3 Marks on user packaging
Unless otherwise specified in the corresponding standard for a particular syringe, the
marking on the user package shall include at least the following information/content:
a) Manufacturer's name and address;
Annex A
(normative)
Test instruments
A.1 General
When the required accuracy (calibration) and precision (Gauge R&R) can be obtained,
any suitable test system can be used. The repeatability and reproducibility (Gauge R&R)
of the test apparatus shall not be greater than 20% of the allowable tolerance range for
any given measurement. For destructive test measurements, Gauge R&R shall not be
greater than 30% of the allowable tolerance range. Its Gauge R&R shall contain at least
±2 standard deviations (thus covering approximately 95% of the variance).
Example:
The measurement system with a measurement specification limit of ±0.01 mL (0.02 mL
range) is from a Gauge R&R with a Gauge R&R/tolerance range ratio of 20%. This
means that its Gauge R&R (4 times standard uncertainty) is equal to
0.02mL/5=0.004mL. The uncertainty of this measurement is ±2 standard deviation
(GUM), which is equal to 0.002mL.
All doses delivered Vset shall be recorded by weighing method, Gmeasurement [in grams
(g)]. These records are converted to volume Vmeasurement at ambient conditions by using
the density ρ of the test liquid [in grams per milliliter (g/mL)]. The weight measurement
value can be converted to volume measurement value with the following formula:
Vmeasurement = Gmeasurement/ρ
A.2 Test solution
The test solution is the original drug solution injected by NIS, or other liquid with
similar physical properties.
A.3 Balance
The balance shall have a division value of at least 1% of the minimum delivered dose.
A.4 Test surface for free fall test
The test surface shall be made of smooth, hard steel with a thickness of 3mm. The
backside shall be made of wood with a thickness greater than 10mm.
needle-based system. For systems classified as D2, the dose resolution requirement
does not apply.
For systems classified as A and C, according to the manufacturer's risk assessment, if a
particular dose is handled differently than the other doses (for example, the first dose
of a system that does not require pre-exhaust), then (after performing dose accuracy as
described above) special considerations need to be taken when analyzing these
particular data points:
a) Each particular data point from a container shall meet the dose accuracy
requirements of the technical specification limits determined by the risk assessment;
b) Those particular dose data points may be excluded from the statistical analysis of
all other doses.
B.2.3.2 Unilateral dose accuracy limits (systems classified as B1 and D1)
The methods are as follows:
a) For user-filled containers, the lower limit of the unilateral technical specification
for the assessment of dose delivery efficiency is determined by the risk assessment.
b) For manufacturer-filled containers, the lower limit of the unilateral technical
specification for the minimum deliverable dose is determined by the drug label.
NOTE: The unilateral (lower limit) case applies only to systems classified as B1 and D1. These two
requirements are the higher the better.
B.2.4 Determination of final dose error and final dose accuracy limit (systems
classified as A and C)
For adjustable dose syringes that are not allowed to set a dose greater than the residual
volume, use Vset equal to Vmin or TP dose as described in B.2.3 to establish the dose
accuracy limit (the manufacturer shall determine the choice based on risk assessment).
For syringes with adjustable doses, if the set dose is allowed to be greater than the
residual volume, the final dose can be assessed by the dose error. This is because normal
variations in system dimensions make it impossible to set the exact same final dose for
all syringes. To accurately evaluate the uncertainty of the final dose, it is necessary to
evaluate a certain number of final doses. Those final doses are required to fall within
10% of TP, so as to calculate the mean dose error for each dose (ideally zero in the
middle). The calculation of the single final dose error (expressed as a percentage) is
shown in the example below. Use 0.20mL of TP:
a) In this example, the final dose within 0.18mL ~ 0.22mL can be used to determine
the final dose accuracy, of which TP is 0.20mL. The range is ±10% of TP. The
remaining final doses above or below this range cannot be used to determine final
B.3 Assessment
B.3.1 General
Dose accuracy is an element required to meet NIS design specifications. If regulatory
requirements are more stringent, or risk assessment requires, the acceptance criteria for
dose accuracy shall be adjusted, so as to ensure that the system meets the requirements.
If these regulatory requirements are not strict, the manufacturer can include them in the
risk assessment as a basis for relaxing the acceptance criteria.
Select and test different numbers of NIS to determine dose accuracy. This number
depends on the vessel and the accuracy requirements for a given test. In the specific
case of user-filled single-dose, NIS needle systems designed to fully empty the
container, it may use dose delivery efficiency to evaluate its accuracy. In the case of
manufacturer-filled single-dose, NIS needle systems designed to fully empty the
container, it may use minimum deliverable dose (that is, the marked volume) to evaluate
the accuracy.
To pass the dose accuracy requirement, at a 95% confidence level, all doses delivered
with at least probability p shall fall within all the upper and lower limits of the three
doses recommended by the specification (one dose in the case of fixed-dose NIS).
To pass the minimum deliverable dose requirement (for manufacturer-filled systems
classified as B1 and D1), at a 95% confidence level, all doses delivered are greater than
the lower limit of the specification with at least probability p. It is defined by the
minimum deliverable dose stated on the drug label.
To pass dose delivery efficiency requirements (for systems with user-filled containers
classified as B1 and D1), at a 95% confidence level, all delivered efficiency, as
probability p, shall exceed the lower limit of dose efficiency according to technical
specifications determined by risk assessment. Calculate the dose delivery efficiency
according to B.2.5.
To pass the final dose accuracy requirement (for systems classified as A and C), when
the syringe allows the set dose to be larger than the residual volume, at a 95%
confidence level, at least all dose error calculations, as probability p, shall fall within
the upper or lower allowable dose error limits recommended by the specification.
For a given test, each syringe can inject each dose in the Vset only once.
The probability p is defined by the specific test and is given in Table 2.
Table B.1 summarizes the provisions required to complete the assessment of dose
accuracy by system notation.
