ASTM E2112 - 01

Revision / Edition: 07      Chg:      Date: 02/01/07STANDARD PRACTICE FOR INSTALLATION OF EXTERIOR WINDOWS, DOORS AND SKYLIGHTS
Document Abstract
This practice covers the installation of fenestration products in new and existing construction. For the purpose of this practice, fenestration products shall be limited to windows, sliding patio-type doors, swinging patio type doors, and skylights, as used primarily in residential and light commercial buildings.
This practice assumes that the ASTM E2112 - 01 Standards installer possesses basic woodworking skills and an understanding of wall and roof construction, sheet metal work, and joint sealant practices.
This practice attempts to instruct and familiarize the installer with the concepts of both Barrier Systems and Membrane/Drainage Systems, in order to ensure the continuity of the building envelope. This practice attempts to educate the installer, builder, architect, and other users in the identification and understanding of the water shedding system of the building envelope.
This practice covers the installation process from preinstallation procedures through post-installation procedures, for single units or factory-mulled multiple units in a single opening. It does not cover the fabrication or assembly of multiple units, whether such fabrication takes place in a factory or at the intended installation site. The installer should check with the manufacturer of factory-assembled units for instructions for anchoring. When using field-mulled units, follow manufacturer's recommendations and make certain that they meet applicable codes. This practice does not cover the selection of appropriate fenestration products for a given application, nor the selection of other products or systems for use in the installation.
This practice provides minimum requirements that will help to accomplish the installation of fenestration products in an effective manner. Actual conditions in buildings vary greatly and, in some cases, substantial additional precautions may be required. In the event that the manufacturer's installation instructions provided with the product conflict with requirements of this practice, the manufacturer's instructions shall prevail. This practice is not intended to limit or exclude other new procedures that may refine or further improve the effectiveness of fenestration installation.
This practice is intended to be used for background information in order to develop training manuals and training programs. Further, this practice attempts to consolidate and unify the various steps of construction, tying together the various trades involved with the continuity between fenestration products and the building envelope.
The text of this practice references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this practice.
The values stated in inch-pound units are to be regarded as the standard. The values shown in parentheses are for information only.
This standard has not been created to address all issues related to every possible installation situation one might experience in the field. Furthermore, this practice does not purport to provide fail-safe installation methods, assurance or protection against installation deficiencies, or a standard by which architects can specify or ensure delivered performance.
NOTE 1—There are no ISO standards covering the primary subject matter of this practice.
This practice 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 to determine the applicability of ASTM E2112 - 01 Standards regulatory limitations prior to use. For specific precautionary statements, see Section 5, Related Procedures. Where a lead hazard is known or suspected, refer to ASTM Standards on Lead Hazards Associated with Buildings and to applicable state and federal regulations. Where an asbestos hazard is known or suspected, refer to the ASTM Manual on Asbestos Control, and to applicable state and federal regulations.

API TR 934-D -2010

Technical Report on the Materials and Fabrication Issues of the 11/4CR-1/2Mo and 1Cr-1/2Mo Steel Pressure Vessels Edition: 1st
American Petroleum Institute / 01-Sep-2010 / 72 pages Scope
This API document provides background information and API TR 934-D -2010 standard guidance on the implementation of API 934-C, Materials and Fabrication of 11/4Cr-1/2Mo Steel Heavy Wall Pressure Vessels for High Pressure Hydrogen Service Operating at Temperatures at or Below 825 °F (426 °C) and API RP 934E, Materials and Fabrication of 11/4Cr-1/2Mo Steel Heavy Wall Pressure Vessels for High Temperature Service Operating Above 825 °F (426 °C), and should be used as a supplement to these recommended practices.
In recent years it has been recognized that there are important distinctions that need to be considered for 11/4/1Cr-1/2Mo steels. Whereas API 934-A continues to provide materials and fabrication requirements for new 21/4/3Cr-1Mo and 21/4/3Cr-1Mo-1/4V steel heavy wall pressure vessels in high temperature, high pressure hydrogen service,
different material, and fabrication requirements have been developed for 11/4/1Cr-1/2Mo steel heavy wall pressure vessels.These requirements are covered in RP 934-C and 934-E.
This document contains a description of key damage mechanisms that relate specifically to 11/4/1Cr-1/2Mo pressure vessels used in a variety of services. These damage mechanisms include elevated temperature damage mechanisms such as “reheat cracking” or “creep embrittlement” as well as other damage mechanisms that may occur at lower temperatures. Not all services are affected by the same damage mechanisms due to significant differences in service conditions. For example, Hydrofiner Reactors tend to operate at lower temperatures and higher pressures than Catalytic Reformer Reactors, and Coke Drums and FCC Reactors do not see hydrogen service. Also, as a result of the different services causing different damage mechanisms, the fabrication requirements also differ. To this end,API has developed two separate recommended practices to take this into account: API 934-C and 934-E.Accordingly, background information and guidance on the implementation of these two new documents are needed.
This document provides information and guidance on successful practices for fabrication of 11/4/1Cr-1/2Mo steel heavy wall pressure vessels for the intended services of both API 934-C and 934-E. The survey of steel producers and vessel fabricators (Annex 1) indicates that there is a need to evaluate the effect of heat treat cycles on materials
properties (CVN toughness, tensile and yield strength). For this reason the connection of the Larson-Miller parameter is emphasized to better align the user needs with fabrication requirements. However, detailed attention is still needed to implement this approach for individual cases, as there are many secondary variables, such as heating and cooling
rates that need to be considered and API TR 934-D -2010 standard discussed between the user and the fabricator. The areas of fabrication that are covered in this document include steel making as related to chemical composition, heat treatment, forming, and welding.

Revision / Edition: 05   ASME B16.21 2005   Chg:      Date: 05/31/05NONMETALLIC FLAT GASKETS FOR PIPE FLANGES
Document Abstract
General
ASME Standard covers types, sizes, materials, dimensions, tolerances, and markings for nonmetallic flat gaskets. These gaskets are dimensionally suitable for use with flanges described in the referenced flange standards
Relevant Units
This Standard states values both in metric and U.S. customary units. As an exception, diameter of bolts and flange bolt holes are expressed in inch units only. These systems of units are to be regarded separately as standard. Within the text, the U.S. customary units are shown in parentheses or in separate tables. The values stated in each system are not exact equivalents; therefore, it is required that each system of units be used independently of the other. Except for diameter of bolts and flange bolt holes, combining values from the two systems constitutes nonconformance with the Standard.
Quality Systems
Requirements relating to the product manufacturers' quality system programs are described in Nonmandatory Appendix A.

Equipment, equipment in the early management is formally put into operation before the series of management, purchase of equipment selection, should be adequate communication, Revision / Edition: 08      Chg:      Date: 11/01/08STANDARD SPECIFICATION FOR SURFACE DISCONTINUITIES OF BOLTS, SCREWS, AND STUDS, INCH AND METRIC SERIESDocument AbstractThis specification establishes allowable limits for the various types of ASTM F788-F788M - 08 surface discontinuities that may occur during the manufacture and processing of bolts, screws, and studs, including heat-treated machine screws, tapping screws, and sems (the washers of screw-washer assemblies are excluded). This specification covers metric series products with nominal diameters of 4 mm and larger and with specified minimum tensile strengths of 420 MPa and higher; and inch series products with nominal diameters of No. 5 (0.1250 in.) and larger and with specified minimum tensile strengths of 60 000 psi and higher.When the engineering requirements of the application necessitate control of surface discontinuities on bolts, screws, or studs, the purchaser shall specify conformance to ASTM Specification F 788/F 788M, in the original inquiry and purchase order.When the engineering requirements of the application necessitate that surface discontinuities on bolts, screws, and studs be controlled within limits closer than those specified in this specification, the purchaser shall specify the applicable limits in the original inquiry and purchase order.The allowable limits established in this specification for metric bolts, screws, and studs with nominal diameters from 4 to 24 mm inclusive, are essentially identical with requirements given in ISO 6157/I. There are no ISO standards for surface discontinuities on any inch-series products.The ASTM F788-F788M - 08 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.*A Summary of Changes section appears at the end of this standard.
