4.1 This test method helps to assess the axial locking force of a modular taper. Some types of devices that may utilize this type of connection are the modular shoulder and modular hip prostheses. Additional means of evaluating the locking mechanisms of tapers may be appropriate, depending upon the design of the device.4.2 This test method may not be appropriate for all implant applications. The user is cautioned to consider the appropriateness of the practice in view of the materials and design being tested and their potential application.4.3 While this test method may be used to measure the force required to disengage tapers, any comparison of such data for various component designs must take into consideration the size of the implant and the type of locking mechanism evaluated.1.1 This test method establishes a standard methodology for determining the force required, under laboratory conditions, to disassemble tapers of implants that are otherwise not intended to release. Some examples are the femoral components of a total or partial hip replacement or shoulder in which the head and base component are secured together by a self-locking taper.1.2 This test method has been developed primarily for evaluation of metal and ceramic head designs on metal tapers but may have application to other materials and designs.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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.5 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.

This specification covers modular gage boards for mounting dial pressure gages and dial thermometers for miscellaneous shipboard applications. Gage boards under this specification are suitable for pressure gages and dial thermometers with either turret or back flanged type cases and with either back or bottom connections. Gage boards may be furnished in two types and grades, namely: Type I, Type II, Grade a, and Grade b. Unless otherwise specified the gage boards shall be manufactured from the specified carbon steel for Grade a and form the specified aluminum alloy for Grade b. Materials shall be capable of being bent at room temperature through the prescribed angle and direction without cracking on the outside of the bent portion. Unless otherwise specified, gage boards shall be drilled for mounting the specified dial sizes. When specified, drilling shall be limited to one size gage for either Type I or Type II gage boards. The dimensional requirements for the gage boards are detailed and illustrated.1.1 This specification covers modular gauge boards for mounting 89-mm [31/2-in.], 114-mm [41/2-in.], 152-mm [6-in.], and 216-mm [81/2-in.] dial size pressure gauges and dial thermometers for miscellaneous shipboard applications.1.2 Gauge boards ordered under this specification are suitable for pressure gauges and dial thermometers with either turret or back flanged type cases and with either back or bottom connections (see Appendix X1).1.3 Gauge mounting dimensions shall be in accordance with ASME B40.1.1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.NOTE 1: Gauge boards covered by this specification are those normally supplied by the shipyard as opposed to the shipyard’s equipment subcontractor.1.5 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.

1.1 This specification covers the functional dimensions and tolerances for tapered cones of proximal femoral stems and the bores of mating ceramic and metal heads. 1.2 This specification does not cover the dimensions of proximal femoral stems other than the cone portion, nor does it cover the dimensions of the ceramic/metal femoral heads, other than the inside tapers. 1.3 The dimensions stated in SI units are to be regarded as the standard. 1.4 The purpose of this specification is to codify matching bore and cone combinations for easy identification. Nonetheless, components from different manufacturers should not be mixed because the combinations of tolerances within the family, surface finish, and configuration from the different manufacturers may not have been validated through axial load strengths or fatigue strength. 1.5 The codification described in this specification represents the most current state of the art at the time of balloting. Future additions can be made but because of the time required to revise the specification, it is recommended that the manufacturer of new combinations label their components with at least the angles until such time that new code letters can be established in accordance with future revisions of this specification.
