23、 Standard is closely related to ISO 7864. Requirements for validated sterilization processes are described in International Standards prepared by ISO/TC 198, Sterilization of health care products. (See references 6 to 8 in Bibliography.) Specific qualitative and quantitative requirements for freedom

24、 from biological hazards are not included in this International Standard but it is recommended that, in assessing possible biological hazards, reference be made to ISO 10993-1, ISO 10993-11 and ISO 7405. This International Standard specifies requirements for dental injection needles with metric size

25、s only. However, attention is drawn to the existence of dental injection needles with imperial threads (see Annex A). 4 DIN EN ISO 7885:2010-06 EN ISO 7885:2010 (E) 1 Scope This International Standard gives dimensional and performance requirements for sterile injection needles for single use which a

26、re used in dental cartridge syringes complying with ISO 9997 for injection of dental local anaesthetics. It further specifies requirements with respect to their packaging, labelling and colour coding. It does not cover needles for special applications or techniques. Only the materials used for the c

27、onstruction of the needle tubing are specified. 2 Normative references The following referenced documents are indispensable for the application of this document.
