Dentistry — Implants — Dynamic loading test for endosseous dental implants

This International Standard specifies a method of dynamic testing of single post endosseous dental implants of the transmucosal type in combination with their premanufactured prosthetic components. It is most useful for comparing endosseous dental implants of different designs or sizes. This International Standard is not a test of the fundamental fatigue properties of the materials from which the endosseous implants and prosthetic components are made. This International Standard is not applicable to dental implants with endosseous lengths shorter than 8 mm nor to magnetic attachments. While this International Standard simulates the functional loading of an endosseous dental implant under “worst case” conditions, it is not applicable for predicting the in vivo performance of an endosseous dental implant or dental prosthesis, particularly if multiple endosseous dental implants are used for a dental prosthesis.


Dentistry — Minimal dental implant data set for clinical use

This International Standard specifies the minimal data set to be recorded for a patient receiving dental implant treatment. This will comprise the locations and types of dental implant bodies, connecting components and adjunctive devices, including grafting materials, placed in a patient’s jaw(s). This information will be recorded by the responsible clinician in the patient’s file and should be made available to the patient by the clinician(s) who provided the care.


Dentistry — Designation system for dental implants

This International Standard provides a system for designating the location of an implant body within a jaw, and is intended for use with the scheme described in ISO 3950. It does not in itself indicate whether the device is visible within the oral cavity or the presence of transmucosal components or implant restorations. Since the system describes location but not restoration form, it is not necessary to use the quadrant designation numbers 5 to 8 which are employed when indicating a primary tooth. This information should be recorded by the responsible clinician in the patient’s file and made available to the patient by the clinician(s) who provided the care.


Dentistry — Implantable materials for bone filling and

This International Standard applies to implantable materials, whether resorbable or non-resorbable, used as dental devices for filling and augmenting bones in oral and maxillofacial surgery.

Evaluation includes the physico-chemical, mechanical, biological and clinical aspects and behaviour of these implantable dental materials. Materials such as autografts, allografts and membranes, and products for which the primary intended use is to deliver a medicinal product, are not covered by this International Standard.

Designation systems for steels - Part 2: Numerical system

1.1 This European Standard specifies a numbering system, referred to as steel numbers, for the designation of steel grades. It deals with the structure of steel numbers and the organization for their registration, allocation and dissemination. Such steel numbers are complementary to steel names set out in EN 10027-1. This European Standard is applicable to steels specified in European Standards. This European Standard may be applied to national steels and proprietary steels. NOTE Although the scope of the systems is limited to steel, it is structured so as to be capable of being extended to include other industrially produced materials. 1.2 Steel numbers established in accordance with this system have a fixed number of digits (see Clause 5). They are better suited for data processing than steel names established in accordance with EN 10027-1. 1.3 For steels specified in European Standards the application for allocation of steel numbers (see A.6 to A.9) is the responsibility of the

This International Standard defines terms and categories in the field of fans used for all purposes. It is not applicable to electrical safety.


Fans -- Dimensions

This International Standard specifies the dimensions of the circular and rectangular flanges of general-purpose fans, as well as the fan size designations. It is not applicable to cross-flow fans or to fan appliances used for individual household or similar applications. For circular flanges, it provides for three different flange series: one for light-duty casing thicknesses, another for medium-duty fans and the third for heavy-duty fans as used on sea-going vessels or in heavy industry. In order not to restrict fan design unduly, only the pitch diameter, hole numbers and hole diameters are specified. Flange thickness, as well as internal and external flange diameters, may be chosen freely within the limits of good engineering practice.

Plastics - Recycled plastics - Determination of selected marker compounds in food grade recycled pol

polyethylene terephthalate (PET). This analytical method provides / is intended to be used as a quality control check. This test identifies and quantifies certain specified contaminants. Such contaminants are referred to as Marker Compounds. The analytical method is applicable for use on PET samples and products at all stages in the recycling process and will therefore be useful to recycling companies producing commercial, recycled PET for food contact materials and articles, and the manufacturers of such articles. This Technical Specification is without prejudice to any existing legislation. NOTE Marker compounds are known to originate from two sources: — from the PET material itself (i.e. residual monomers, degradation products or reaction/breakdown products); — from food products that the PET has contacted during its “first use”.
