Sterile hypodermic syringes for single use - Part 3: Auto-disabled syringes for fixed-dose immunization (ISO 7886-3:2020)

EN-ISO 7886-3 specifies the properties and performance of sterile single-use hypodermic syringes with an auto-disable syringe feature intended to deliver a fixed dose of vaccine immediately after filling. The syringes can be made of plastic, rubber or other materials and can be with or without needle and needle protection feature.This document does not specify the design of the auto-disable syringe feature.This document is not applicable to syringes for use with insulin (covered by ISO 8537), syringes for use with power-driven syringe pumps (covered by ISO 7886-2), reuse prevention syringes (covered by ISO 7886-4) or syringes designed to be prefilled (covered by the ISO 11040 series). It does not address compatibility with injection fluids/vaccines.

Die Spritzen können aus Kunststoff, Gummi oder anderen Werkstoffen gefertigt, und mit oder ohne Kanüle und Kanülenschutzvorrichtung gefertigt sein.
Dieses Dokument legt nicht die Gestaltung des Selbstblockierungsbauteils einer Spritze fest.
Dieses Dokument gilt nicht für Insulinspritzen (behandelt in ISO 8537), Spritzen für Druckinfusionsapparate (behandelt in ISO 7886 2), Spritzen mit Vorrichtung zur Verhinderung der Wiederverwendung (behandelt in ISO 7886 4) oder zur Vorfüllung ausgelegte Spritzen (behandelt in der Normenreihe ISO 11040).

Seringues hypodermiques stériles, non réutilisables - Partie 3: Seringues autobloquantes pour vaccination à dose fixe (ISO 7886-3:2020)

Le présent document spécifie les propriétés et les performances des seringues hypodermiques stériles, non réutilisables, dotées d'un système autobloquant, prévues pour délivrer une dose fixe de vaccin immédiatement après remplissage. Les seringues peuvent être en plastique, en caoutchouc et en d'autres matériaux et peuvent être avec ou sans aiguille et avec ou sans dispositifs de protection contre les piqûres d'aiguilles.
Le présent document ne spécifie pas la conception du système autobloquant.
Le présent document n'est pas applicable aux seringues à insuline (couvertes par l'ISO 8537), aux seringues pour pousse-seringues électriques (couvertes par l'ISO 7886‑2), aux seringues avec dispositif empêchant la réutilisation (couvertes par l'ISO 7886‑4) ou aux seringues conçues pour être préremplies (couvertes par la série ISO 11040).

SIST EN ISO 7886-3:2020
ISO 7886-3:2020(E)
Introduction

ISO 7886 was first published in 1984. It was subsequently decided to divide it into two parts: ISO 7886-1

retaining essentially the scope of ISO 7886:1984 and ISO 7886-2 being applicable to sterile, single-use

syringes for use with power-driven pumps.

The preparation of this document was recognized as a high priority to prevent the reuse of fixed dose

immunization syringes. Reuse of injection equipment in the absence of sterilization has increasingly led

to transmission of blood-borne pathogens.

The World Health Organization (WHO) had produced a specification for syringes that are rendered

inactive after one use (commonly referred to as “auto-disabled” syringes). It was agreed that an

additional part of the ISO 7886 series would be needed to cover “auto-disabled” syringes, while leaving

in place ISO 7886-1 and ISO 7886-2 without modification, as a large number of devices in common use

would not be intended to conform with the auto-disable properties suggested.

It has been discussed to limit the syringe types to only comprise the type having an auto-disable

syringe feature that is automatically activated and remains effective from the time that the injection

is commenced. An assessment of potential hazards based only on hypothetical use indicates that the

type having an auto-disable syringe feature that is automatically activated and remains effective from

the time of the injection being initiated is potentially safer than the other types. However, no consensus

could be reached on either deleting types or retaining them, as no reliable risk data from field use

exists at present. It was therefore agreed to retain all types and restrict this revision to alignment with

ISO 7886-1:2017 and initiate a new revision if new field studies or incident reports indicate a need for a

revision.

It is recognized that syringes designed to reduce the risk of needle stick injuries can also conform with

this document.

In some countries national regulations might take precedence over the requirements in this document.

Guidance on transition periods for implementing the requirements of this document is given in

ISO/TR 19244.

Auto-disabled syringes for fixed-dose immunization
1 Scope

This document specifies the properties and performance of sterile single-use hypodermic syringes with

an auto-disable syringe feature intended to deliver a fixed dose of vaccine immediately after filling.

The syringes can be made of plastic, rubber or other materials and can be with or without needle and

needle protection feature.
This document does not specify the design of the auto-disable syringe feature.

This document is not applicable to syringes for use with insulin (covered by ISO 8537), syringes for

use with power-driven syringe pumps (covered by ISO 7886-2), reuse prevention syringes (covered by

ISO 7886-4) or syringes designed to be prefilled (covered by the ISO 11040 series). It does not address

compatibility with injection fluids/vaccines.

subsequent reuse of the syringe and the needle

Note 1 to entry: A passive activation is an activation of the reuse prevention feature that does not require an

additional step by the user, separate from any action needed to perform the primary intended injection function

of the device.

Note 2 to entry: An active activation is an activation of the reuse prevention feature that does require an

additional step by the user.

5 General requirements

The general requirements listed below are considered to be design input for manufacturers.

a) Syringes shall be free from defects affecting appearance, safety and serviceability for their

intended use. 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 requirements 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. This document does not specify

materials to be used for the construction and lubrication of the device, because their selection will

SIST EN ISO 7886-3:2020
ISO 7886-3:2020(E)

depend, to some extent, upon the manufacturer’s specific syringe design, process of manufacture

and sterilization method.

b) Syringes with integrated or add-on sharps protection shall conform with ISO 23908.

c) The length of the barrel shall allow the expulsion of any air bubbles without removal of the plunger

stopper and still inject nominal capacity. The length of the barrel shall be designed to enable

accurate dosage while avoiding unnecessary waste of vaccine.

d) Biocompatibility of the syringe shall be established in accordance with ISO 10993-1.

e) The auto-disabled syringe shall be of adequate size, shape and strength for the delivery of vaccine

under normal condition of use. The design specifications for the device shall be determined through

risk analysis and confirmed through usability validation testing.

f) The forces required to use a syringe with auto-disable syringe feature shall be appropriate for

the intended users of the device. Although the activation of the auto-disable syringe feature itself

is passive, an appropriate force shall be selected that eases the initiation of the injection. The

appropriate initiation force shall be determined using a risk-based approach in accordance with

ISO 14971.
6 Extraneous matter
6.1 General
The requirements specified in ISO 7886-1:2017, 6.1, apply.
6.2 Limits for acidity or alkalinity

The requirements specified in ISO 7886-1:2017, 6.2, apply except that the extracts shall be prepared in

accordance with Annex A of this document.
6.3 Limits for extractable metals
The requirements specified in ISO 7886-1:2017, 6.3, apply.
7 Lubricant

The requirements specified in ISO 7886-1:2017, Clause 7 and ISO 7864:2016, 4.10.4, apply.

8 Tolerance on nominal capacity

The volume of water at (23 ± 5) °C expelled from the syringe when the fiducial line of the piston traverses

the full scale (i.e. the nominal fixed dose) shall be within the tolerances on the nominal capacity as

specified in Table 1. The nominal capacity shall be designated in millilitres.
