4.1 This specification defines the area wherein parts of the binding may be mounted. Standard dimensions and location for a binding mounting area enable a ski designer to locate reinforcing elements within this area. Standard dimensions also enable the binding designer to determine all interface dimensions for binding unit size, screw locations, etc. Bindings and skis built in compliance with this specification are compatible. This specification does not apply to any bindings or skis manufactured prior to Jan. 1, 1979.AbstractThis specification covers dimensions for binding mounting areas to be used in alpine skis and mounting-related dimensions on alpine ski bindings, in order to optimize the compatibility of the functional unit" ski-binding-retention device- boot." The area wherein parts of the binding may be mounted is defined. Standard dimensions and location for a binding mounting area enable a ski designer to locate reinforcing elements within this area. Standard dimensions also enable the binding designer to determine all interface dimensions for binding unit size, screw locations, etc.1.1 This specification covers2 dimensions for binding mounting areas for alpine skis and mounting-related dimensions on alpine ski bindings as part of an interface (“ski-binding-boot”) system, in order to optimize the compatibility of the functional elements of the system. It contains data needed for the manufacture of alpine skis, and for manufacturers of alpine ski bindings, specifically with respect to the binding mounting area. This specification is applicable to alpine skis of the following chord lengths (see Terminology F472 for the definition of chord length, LN):Group 1: LN ≥ 1700 mmGroup 2: 1400 mm ≤ LN < 1700 mmGroup 3: 1000 mm ≤ LN < 1400 mmGroup 4: 750 mm ≤ LN < 1000 mm1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 Dimensional measurements of the product thermal insulation are essential in determining compliance of a product with specification limits. Dimensional measurements of various test specimens are also required by the specific test method.5.2 Density measurements of the product insulation are useful in determining compliance of a product with specification limits, and in providing a relative gage of product weights. For any one kind of insulation, some important physical and mechanical properties, such as thermal conductivity, heat capacity, strength, etc., bear a specific relationship with its density. In order to design for equipment supports, check the material for the “as received density” where the moisture content of the product as received and then installed has the potential to be consequential.1.1 This test method covers determination of the dimensions and density of block and board insulation as defined in Terminology C168.1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 The term “surface texture” is used to describe the local deviations of a surface from an ideal shape. Surface texture usually consists of long wavelength repetitive features that occur as results of chatter, vibration, or heat treatments during the manufacture of implants. Short wavelength features superimposed on the long wavelength features of the surface, which arise from polishing or etching of the implant, are referred to as roughness.4.2 This guide provides an overview of techniques that are available for measuring the surface in terms of Cartesian coordinates and the parameters used to describe surface texture. It is important to appreciate that it is not possible to measure surface texture per se, but to derive values for parameters that can be used to describe it.1.1 This guide describes some of the more common methods that are available for measuring the topographical features of a surface and provides an overview of the parameters that are used to quantify them. Being able to reliably derive a set of parameters that describe the texture of biomaterial surfaces is a key aspect in the manufacture of safe and effective implantable medical devices that have the potential to trigger an adverse biological reaction in situ.1.2 This guide is not intended to apply to porous structures with average pore dimensions in excess of approximately 50 nm (0.05 μm).1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
