ISO 7886-1:2017(E)
Introduction
The ISO 7886 series covers 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 standards on quality systems, for example the ISO 9000
series and 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.
INTERNATIONAL STANDARD ISO 7886-1:2017(E)
Sterile hypodermic syringes for single use —
Part 1:
Syringes for manual use
1 Scope
This document specifies requirements and test methods for verifying the design of empty sterile single-
use hypodermic syringes, with or without needle, made of plastic or other materials and intended for
the aspiration and injection of fluids after filling by the end-users. This document does not provide
requirements for lot release. The syringes are primarily for use in humans.
Sterile syringes specified in this document are intended for use immediately after filling and are not
intended to contain the medicament for extended periods of time.
It excludes syringes for use with insulin (see ISO 8537), single-use syringes made of glass, syringes for
use with power-driven syringe pumps, syringes pre-filled by the manufacturer, and syringes intended
to be stored after filling (e.g. in a kit for filling by a pharmacist).
Hypodermic syringes without a needle specified in this document are intended for use with hypodermic
needles specified in ISO 7864.

5 General requirements
The general requirements are considered to be design inputs for manufacturers.
a) Syringes shall be free from defects affecting appearance, safety and performance for their intended
use. Syringes with integrated or add-on sharps protection shall 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 usability validation testing.
— The materials shall not cause the syringes to yield, under conditions of normal use, significant
amounts of toxic substances and shall permit them to satisfy the appropriate national
requirements or regulations for freedom from pyrogenic materials and abnormal toxicity.
— Materials used in the construction of the wall of the syringe barrel shall have sufficient clarity
to enable dosages to be read without difficulty.
— The standard 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.
b) The design and validation of the packaging shall take into consideration the final use of the syringe
and the storage and shipping conditions and the defined shelf life.
6 Extraneous matter
6.1 General
The surfaces of the syringe that come in contact with injection fluids during normal use shall be free
from particles and extraneous matter.
NOTE Compliance with this requirement will be determined through inspection by an individual with
normal vision (or corrected-to-normal vision), without magnification.
6.2 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.
The pH value of both solutions may be determined with a laboratory potentiometric pH meter using a
general purpose electrode.
6.3 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).
ISO 7886-1:2017(E)
7 Lubricant
When the plunger stopper is fully inserted the amount of lubricant applied into the barrel shall not
reach the Luer channel of the nozzle.
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.
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.
8 Tolerance on graduated capacity
The tolerances on the graduated capacity shall be as given in Table 1.

9 Graduated scale
9.1 Scale
9.1.1 The syringe shall have either only one scale or more than one identical scales, 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.
If necessary by a specific application, the scale may vary and this requirement does not preclude the
provision of additional graduation marks within the scale or as extensions to the scale. Any variation of
the scale or graduation is recommended to be assessed for risk according to ISO 14971 and for usability
according to IEC 62366.
9.1.2 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;
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.
9.1.3 Graduation lines shall be of uniform thickness. They shall lie in planes at right angles to the axis
of the barrel.
