Introduction
The ISO 7886 series cover hypodermic syringes primarily intended for human use and provides performance
and testing requirements. It permits broader variation in design so as not to limit innovation and methods of
packaging. Its appearance and layout are consistent with other related standards which are designed to be
more performance-based compared to design prescriptive.
General requirements as design guidelines for manufacturers are introduced in this document. Several
limits for requirements which are historic based but confirmed in practice for many years have been kept.
Materials to be used for the construction and lubrication of sterile syringes for single use are not specified as
their selection will depend to some extent upon the design, process of manufacture and sterilization method
employed by individual manufacturers. The materials of the syringe should be compatible with injection
fluids. If this is not the case, the attention of the user should be drawn to the exception by labelling on unit
packaging. It is not practicable to specify a universally acceptable test method for incompatibility, as the
only conclusive test is that an individual specific injection fluid is compatible with a specific syringe.
Manufacturers of pharmaceuticals use solvents in injectable preparations. Such solvents should be tested by
the manufacturer of the injectable preparation for any possible incompatibility with the materials frequently
used in syringe construction. If an incompatibility is identified, the injection fluid should be suitably labelled.
The impossibility of testing any one injection fluid with all available syringes is recognized and it is strongly
recommended that regulatory authorities and relevant trade associations should recognize the problem and
take appropriate measures to assist manufacturers of injectable preparations.
Syringes should be manufactured and sterilized in accordance with recognized national or international
codes of good manufacturing practice for medical devices.
The sampling plans for inspection selected for the ISO 7886 series are intended to verify the design at a high
confidence level. The sampling plans for inspection do not replace the more general manufacturing quality
systems requirements that appear in quality management systems, e.g. ISO 9001 or ISO 13485.
Manufacturers are expected to follow a risk-based approach and employ usability engineering during the
design, development and manufacture of syringes.
Guidance on transition periods for implementing the requirements of ISO 7886 (all parts) is given in
ISO/TR 19244.

5 Requirements
5.1 General requirements
The general requirements are considered to be design inputs for manufacturers.
Syringes shall be free from defects affecting appearance, safety and performance for their intended use.
Syringes with integrated or add-on sharps protection shall also comply with ISO 23908.
The syringe’s barrel flanges shall be of adequate size, shape and strength for the intended purpose. The
design specifications for the barrel flanges shall be determined through risk analysis and confirmed through
the application of usability engineering according to IEC 62366-1.
5.2 Material selection
The materials shall satisfy the appropriate national requirements or regulations for freedom from regarding
acceptable levels of pyrogens and toxins appropriate to the intended use of the product.
Materials used in the construction of the wall of the syringe barrel shall have sufficient clarity to enable the
user to read dosages with normal or corrected to normal vision and environmental lighting conditions of <
100 lx, and from a reading distance of between 30 cm and 70 cm.
NOTE 1 The legibility of markings inspection is supposed to ensure that users of needle based injection systems
(NIS) are able to read the markings under real life conditions (e.g. limited light intensity).
NOTE 2 The lighting levels chosen for this subclause were the lowest levels listed in ISO 8995-1 and depict ambient
lighting levels that are likely to be seen in private homes or in the entrance halls, rest rooms or corridors of public
spaces (e.g. hotels or hospitals). This level is chosen as representative of what patients – users of these syringes - can
be expected to encounter as they look to read markings on these devices. Other lighting levels can be appropriate
based on the intended use of the syringe.
The document does not specify materials to be used for the construction and lubrication of sterile syringes
with or without needles for single use, because their selection will depend, to some extent, upon the
manufacturers specific syringe design, process of manufacture and sterilization method.
5.3 Extraneous matter
5.3.1 General
The surfaces of the syringe that come in contact with injection fluids during normal use shall be free from
particles and extraneous matter when inspected without magnification, with normal or corrected to normal
vision under an illuminance of min. 500 lx, and from a reading distance of between 30 cm and 70 cm.
NOTE 1 Compliance with this requirement will be determined through inspection by an individual with normal
vision (or corrected-to-normal vision), without magnification.
NOTE 2 The lighting levels chosen for this subclause were the lighting levels listed in ISO 8995-1 expected to be
seen in inspection areas in the chemical, plastics or rubber industry.
5.3.2 Limits for acidity or alkalinity
Exposure of distilled water to the finished syringe product shall not change its pH value by more than one unit.
Compliance with this requirement shall be demonstrated by preparing the solutions described in Annex A.
The results shall show that the pH value of the syringe assessment fluid is within one pH unit of the pH value
of the control fluid.
ISO/DIS 7886-1:2025(en)
The pH value of both solutions may be determined with a laboratory potentiometric pH meter using a
general purpose electrode.
5.3.3 Limits for extractable metals
Exposure of distilled water to the finished syringe product shall not change its content of metals by more
than a combined total of 5 mg/kg of lead, tin, zinc and iron; the cadmium content shall be less than 0,1 mg/kg.
Compliance with this requirement shall be demonstrated by preparing the solutions described in Annex A
and testing them using a recognized micro-analytical method, for example, by an atomic absorption method
or by an inductively coupled plasma mass spectrometry method (ICP).
NOTE The test to be performed whenever there is any change in construction material.
5.3.4 Pyrogenicity
Pyrogenicity mediated by endotoxin can be measured by an endotoxin-specific LAL (Limulus Amebocyte
Lysate) test, referring to the specific test given in AAMI/ST72 as suggested by ISO 10993-11:2017, Annex G.
Other references to this test can be found in USP <85> and/or EU pharmacopeia.
Extraction method and testing are specified in regional and national pharmacopoeias:
— for extraction method, see USP <161>;
— for testing, see Ph.Eur., 2.6.14, method c), USP <85> and JP 4.01
5.3.5 Biocompatibility
Biocompatibility evaluation of syringes shall be in compliance to ISO 10993 series.
5.3.6 Limits for particulate matters
Sterilized syringes shall be manufactured by processes that minimize the risk of particulate contamination
of the intended content.
The particle-related specifications given in pharmacopoeias (e.g. Ph.Eur., USP, JP) do not apply to empty
containers but to show a certain cleanliness level, specifications have been set.
For sub-visible particles, the following applies:
— particles ≥10 µm: 3 000 max. per syringe;
— particles ≥25 µm: 300 max. per syringe.
NOTE These limits have been derived from the USP <788> (small volume parenterals) limit values for filled
containers with a nominal volume of less than 100 ml. The limits, which is 50 % of the USP <788>, have been chosen
based on historical proven capability using the light obscuration method as given in Annex G.
5.4 Lubricant
For lubricants applied to interior surface of the syringe, the quantity of lubricant applied shall not exceed
0,25 mg/cm of the interior surface area of the syringe in contact with the injection fluid.
The amount and distribution of lubricant applied should be optimized to minimize lubricant visibility.
NOTE 1 An acceptable lubricant is silicone complying with a national or the European pharmacopoeia and
ISO 10993-1.
ISO/DIS 7886-1:2025(en)
For lubricants incorporated in the polymer formulation, the quantity of lubricant shall not exceed 0,6 %
(w/w) of the mass of the component, but attention is drawn to the fact that some national regulations may
specify a lower maximum concentration.
NOTE 2 If a lubricant is incorporated in the polymer formulation, visible particles can become apparent when the
lubricant blooms to the surface of the syringe barrel and the plunger stopper scrapes it off.
NOTE 3 Example of acceptable lubricants incorporated in the polymer formulation are fatty acid amides of erucic
and/or oleic acids complying with ISO 10993-1.
NOTE 4 See Annex F for a test method for the quantity of silicone oil.
5.5 Dimensions
5.5.1 Barrel
Maximum capacity shall be determined by risk assessment with consideration of, for example, removal of
air bubbles or risk of overdose.
5.5.2 Barrel flanges
The open end of the barrel shall be provided with barrel flanges. Barrel flanges shall be of adequate size,
shape and strength for the intended purpose and shall enable the syringe to be held securely during use.
5.6 Plunger stopper/plunger assembly
When tested in accordance with Annex B, the plunger stopper shall not become detached from the plunger.
The plunger shall be of a length adequate to allow the plunger stopper to traverse the full length of the
barrel. By risk assessment, the manufacturer shall set and verify a specification for an increased force for
removal of the piston completely from the barrel.
The projection of the plunger and the configuration of the push-button should be such as to allow the
plunger to be operated without difficulty. When the fiducial line of the plunger stopper coincides with the
zero graduation line, the minimum length of the plunger from the surface of the barrel flanges nearer to the
push-button, as shown in Figure 3, shall be at least 8 mm.
Key
1 minimum 8 mm
Figure 2 — Minimum length between barrel flanges and plunger push-button
The syringe design, such as barrel flanges, shall be such that the syringe will not roll more than 180° when it
is placed on a flat surface at an angle of 10° to the horizontal. The barrel flanges shall be free from flash and
sharp edges.
ISO/DIS 7886-1:2025(en)
Finger grip configurations that do not conform to these requirements are recommended to be assessed for
risk according to ISO 14971 and for usability according to IEC 62366.
5.7 Nozzle
5.7.1 Conical fitting
The male conical fitting of the syringe nozzle shall be in accordance with ISO 80369-7.
If the syringe has a locking fitting, it shall be in accordance with ISO 80369-7.
5.7.2 Position of nozzle on end of barrel
5.7.2.1 On syringes of nominal capacity of less than 5 ml, the syringe nozzle shall be situated centrally, i.e.
it shall be coaxial with the barrel.
5.7.2.2 On syringes of nominal capacity of 5 ml and greater, the syringe nozzle shall be situated either
centrally or eccentrically.
5.7.2.3 If the syringe nozzle is eccentric, its axis shall be vertically below the axis of the barrel when the
syringe is lying on a flat surface with the scale uppermost. The distance between the axis of the nozzle and
the nearest point on the internal surface of the bore of the barrel shall be not greater than 4,5 mm.
5.7.3 Nozzle lumen
The nozzle lumen shall have a diameter of not less than 1,2 mm.
5.8 Standard test environmental conditions
Unless otherwise specified, measurements shall be performed under the following atmospheric conditions:
— temperature between 18 °C and 28 °C;
— relative humidity between 25 % RH and 75 % RH.
Testing shall be performed after samples have been stored under these conditions for at least 4 h.
5.9 Tolerance on graduated capacity
The tolerances on the graduated capacity shall be as given in Table 1.

Dead Space as designated in Table 2.
EXAMPLE 1 For a 3 ml syringe, when filled to the 1 ml graduation (less than 1/2 capacity), the required tolerance would be ±(1,5 % × 3 ml + 2 % × 1 ml) = 0,065 ml
EXAMPLE 2 For a 3 ml syringe, when filled to the 2 ml graduation (greater than 1/2 capacity), the required tolerance would be ±(5 % × 2 ml) = 0,100 ml.
EXAMPLE 3 For a 1 ml syringe, when filled to the 0,1 ml graduation (less than 20 % nominal capacity), the required tolerance would be ±10 % = 0,01 ml

5.10 Graduated scale
5.10.1 Scale
5.10.1.1 The syringe shall have either only one scale or more than one identical scale, which shall be graduated
and numbered at least at the intervals given in Table 1. The unit of volume shall be marked on the barrel.
NOTE The scale interval can be less (finer) than the scale interval given in Table 1.
5.10.1.2 The total graduated capacity may be equal to, or greater than, the nominal capacity. If the scale is
extended beyond the nominal capacity, the extended portion shall be differentiated from the rest of the scale.
Examples of means of differentiation are the following:
a) encircling the scale number of the nominal capacity line;

ISO/DIS 7886-1:2025(en)
b) using smaller scale numbers for the extra graduation lines;
c) using shorter graduation lines for the extra graduation lines;
d) using a broken line for the optional vertical line of the extra scale length.
5.10.1.3 Graduation lines shall be of uniform thickness. They shall lie in planes at right angles to the axis of
the barrel.
5.10.1.4 Graduation lines shall be evenly spaced along the longitudinal axis between the zero graduation
line and the line for the total graduated capacity.
5.10.1.5 When the syringe is held vertically, the ends of all graduation lines of similar length shall be
vertically beneath each other.
The lengths of the short graduation lines on each scale are recommended to be approximately half the length
of the long lines. If different graduation line configurations are used, this could be submitted to usability
evaluation according to IEC 62366.
Examples of scales and the numbering of graduation lines are shown in Figure 3.
NOTE 1 The vertical line of the scale may be omitted.
NOTE 2 The figure is not to scale.

5.10.2 Numbering of scales
5.10.2.1 Graduation lines shall be numbered at least at the volume increments given in Table 1. In addition,
the line denoting the nominal capacity or the lines denoting the nominal capacity and the total graduated
capacity, if these differ, shall be numbered.
Examples of scale numbering are shown in Figure 2.
5.10.2.2 When the syringe is held vertically with the conical tip uppermost and with the scale to the front,
the numbers shall appear vertical on the scale and be approximately centred on the graduation lines to
