This European
20、Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by February 2014, and conflicting national standards shall be withdrawn at the latest by February 2014. Attention is drawn to the possibility that some of the elemen

This document supersedes EN 21563:1991, EN ISO 13716:2000, EN ISO 1564:1998. This first edition of ISO 21563 constitutes a consolidation of the thr
22、ee standards listed below and, as such, cancels and replaces, in whole, all three of the standards listed.

23、 materials systems Re-evaluations of all the provisions stated in the three ISO standards to be included in the consolidation led to the significant technical changes listed as follows. The alginate hydrocolloid impression materials (ISO 1563) are now required to be subject to the same tear strength
24、 test that has been in effect for the agar hydrocolloid impression materials (ISO 1564 and ISO 13716) instead of being subject to a compressive strength test. The requirement for the alginate impression material powder materials to be “free from foreign materials”, as stated in ISO 1563, has not bee
25、n carried forward into the consolidation because no objective test has been specified for determining compliance with the requirement. The “gelation temperature” requirements in ISO 1564 and ISO 13716 have not been carried forward for the agar impression materials because results of the elastic reco
26、very test (7.5), if conducted following the required manufacturers instructions for use (8.2.1 and/or 8.2.2), will indicate whether adequate gelation will take place during clinical use of the materials. According to the CEN-CENELEC Internal Regulations, the national standards organizations of the f
27、ollowing countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherland

30、 of the inquiring parties.DIN EN ISO 21563:2013-12 EN ISO 21563:2013 (E) 4 1 ScopeThis International Standard specifies the requirements and tests for helping determine whether the elastic aqueous agar and alginate hydrocolloid dental impression materials, as prepared for retail marketing, are of th
31、e quality needed for their intended purposes. It also specifies requirements for labelling and instructions for use.NOTE This International Standard specifies no requirements or tests for freedom from unacceptable biological hazards. However, it is recommended that, to address possible biological ha
32、zards associated with the use of hydrocolloid impression materials, interested parties should refer to ISO 7405 and ISO 10993.2 Normative referencesThe following referenced documents are indispensable for application of this document.

44、instructions, it can be assumed that the product is of a quality suitable for testing or use; in the development of standards for certain materials when there is a need for a standard to identify a reference point in time that can be used as a basis for specifying a later point in time at which a su
