ISO 8537:2007 specifies requirements and test methods for sterile syringes, with or without needles, solely for the injection of insulin. The syringes are single-use only, primarily for use in humans. It covers syringes for use with 40 units of insulin/ml (U-40) and 100 units of insulin/ml (U-100). Sterile syringes specified in ISO 8537:2007 are intended for use soon after filling as they are not suitable for containing insulin over extended periods of time. ISO 7886-3:2005 specifies the properties and performance of sterile single-use hypodermic syringes with or without needle, made of plastic materials and stainless steel and intended for the aspiration of vaccines or for the injection of vaccines immediately after filling. Upon delivering a fixed dose of vaccine the syringe is automatically rendered unusable. ISO 7886-3:2005 does not specify the design of the auto-disable feature, which is left to the discretion of the manufacturer ISO 7886-3:2005 is not applicable to syringes for use with insulin (specified in ISO 8537), syringes made of glass (specified in ISO 595), syringes for use with power-driven syringe pumps (specified in ISO 7886-2), auto-disable syringes for variable dose delivery and syringes designed to be prefilled. It does not address compatibility with injection fluids/vaccines. Available from http://iso.org
