17、O/TS 16506:2017(E) Introduction This document provides test methods and information of performances for polymer-based restorative materials for luting which contain adhesive components. Test methods specified in this document used for a group of materials with varying compositions has proved difficu
18、lt to set performance limits. Evidence is needed from using this document to develop it into an International Standard. Specific qualitative and quantitative test methods for demonstrating freedom from unacceptable biological risks are not included in this document but it is recommended that, for as
19、sessment of such biological risks, reference should be made to ISO 10993-1 and ISO 7405.vi ISO 2017 All rights reserved Dentistry Polymer-based luting materials containing adhesive components 1 Scope This document specifies test methods and information of bond strength to dentine and physical and ch
20、emical performances of dental polymer-based luting materials containing adhesive components. The materials are supplied in a form suitable for mechanical mixing or hand-mixing, including using auto-mixing tips, for self-curing and/or external energy activation, or non-mixing for external energy acti
21、vation. The polymer-based luting materials covered by this document are intended to be used for the cementation or fixation of restorations and appliances such as inlays, onlays, veneers, posts, crowns and bridges. This document does not cover the following polymer-based luting materials: a) those w
22、hich do not have an adhesive component within the structure of the material (see ISO 4049); b) those intended for veneering sub-frames (see ISO 10477). 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements

32、.2 ISO 2017 All rights reserved ISO/TS 16506:2017(E) 6 Sampling The test sample shall consist of packages prepared for retail sale from the same batch or lot containing enough material to carry out the specified tests, plus an allowance for repeat tests, if necessary. 50 g should be sufficient. 7 Te
33、st methods 7.1 General a) Reagent Water For the tests, use water prepared in accordance with ISO 3696 Grade 2. b) Equipment Validate all test equipment prior to use. 7.2 Test conditions Unless specified otherwise, prepare and test all specimens at (23 2) C. Control the relative humidity to ensure th
34、at it remains (50 20) % at all times. If the material was refrigerated, e.g. for storage, allow it to attain (23 2) C. For Class 3 materials, perform the tests for film thickness (see 7.5), working time (see 7.6) and setting time (see 7.7) in the absence of activating radiation. Ambient light, both
35、natural and artificial, is capable of activating Class 2 and Class 3 materials. For good control, the test should be performed in a darkened room with any artificial light filtered by a yellow filter. 1) 7.3 Inspection Inspect visually to check that requirements specified in Clause 8 have been met.
36、7.4 Preparation of test specimens For the preparation of Class 2 and Class 3 materials, refer to the manufacturers instructions for use see 8.3 d) that states the external energy source or sources recommended for the materials to be tested. Ensure that the source is in a satisfactory operating condi
37、tion. NOTE ISO 10650 gives guidance on this. Mix or otherwise prepare the material in accordance with the manufacturers instructions for use and the test conditions specified in 7.2. When fully cured specimens are required for testing (7.10 to 7.12), ensure that the specimens are homogeneous after r
38、emoval from the mould. Discard any specimens containing clefts, voids, discontinuities or air inclusions when inspected visually without magnification. 1) Polyester filter 101, Lee Filters, Andover, Hants, UK is an example of a suitable product available commercially.

40、25) mm 2and a uniform thickness not less than 5 mm. 7.5.1.2 Loading device, of the type illustrated in Figure 1 or an equivalent means, whereby a force of (150 2) N can be applied vertically to the specimen via the upper glass plate. In Figure 1, the anvil that is attached to the bottom of the rod i
41、s horizontal and parallel to the base, such that the load can be applied smoothly and without rotation of the specimen. NOTE A holder can be used to assist in the positioning of the plates. Such a device consists of a base-plate with three vertical pins to align circular plates or four pins to align
42、 square plates. 7.5.1.3 External energy source (for Class 2 and Class 3 materials), as recommended by the manufacturer for use with the test material. 7.5.1.4 Micrometer, accurate to at least 0,5 m.

Remove the upper plate and place between 0,02 ml a
44、nd 0,10 ml of the test material prepared in accordance with the manufacturers instructions for use in the centre of the lower plate and centre the plate below the loading device (7.5.1.2) on its lower plate.

46、80 10) s. Ensure that the cement has completely filled the space between the glass plates. At least 10 min after the commencement of mixing, remove the plates from the loading device and measure the combined thickness of the two glass plates and the specimen film, again taking the reading in the cen
47、tre of the plates (reading B). Record the difference between reading A and reading B, to the nearest micrometre, as the film thickness of the material. Carry out five determinations. 7.5.2.3 Class 2 and Class 3 materials Immediately after dispensing Class 2 materials or at (60 2) s after the complet
48、ion of mixing Class 3 materials, apply a force of (150 2) N vertically and centrally to the specimen via the top plate smoothly and in such a manner that no rotation occurs for (180 10) s. Ensure that the specimen has completely filled the space between the glass plates. After (180 10) s, release th
49、e load and irradiate the specimen through the centre of the upper glass plate for twice the exposure time recommended by the manufacturer. NOTE This irradiation is not intended to cure the material totally, but to stabilize the specimen for measurement. After the irradiation of Class 2 and Class 3 materials, remove the plates from the loading device and measure the combined thickness of the two glass plates and the specimen film, again taking the reading in the centre of
