In August 2010 ASME released a new edition of BPV Code. It consists of 12 volumes and two code cases. Also there are several convenient set that come with a lower price tag. All volumes can be obtained in printed and printed/online edition.
All other ordering options are available via Techstreet
ASME released this standard on Jul 30, 2009. It has 238 pages and covers pressure-temperature ratings, materials, dimensions, tolerances, marking, testing, and methods of designating openings for pipe flanges and flanged fittings.
Included are:

This standard is available as secure PDF for immediate download or in printed edition, that is usually shipped within 1 or 2 business days.
This Standard provides methods for repair of equipment and piping within the scope of ASME Pressure Technology Codes and Standards after it has been placed in service. These repair methods include relevant design, fabrication, examination, and testing practices and may be temporary or permanent, depending on the circumstances. The methods provided in this Standard address the repair of components when repair is deemed necessary based on appropriate inspection and flaw assessment. These inspection and flaw evaluation methods are not covered in this document, but are covered in other post-construction codes and standards. Only technical procedures and information are provided; administrative or policy requirements are outside of the scope of this Standard.
As usual this ASME standard is available in printed and PDF edition.
Process Piping
This 258 page standard was published on Mar 31, 2009 by American Society of Mechanical Engineers.
This Code is applicable to piping in gaseous and liquid hydrogen service and to pipelines in gaseous hydrogen service. This Code is applicable up to and including the joint connecting the piping to associated pressure vessels and equipment but not to the vessels and equipment themselves. It is applicable to the location and type of support elements but not to the structure to which the support elements are attached. This Code is presented in the following parts:
(a) Part GR — General Requirements. This part contains definitions and requirements for materials, welding, brazing, heat treating, forming, testing, inspection, examination, operation, and maintenance.
(b) Part IP — Industrial Piping. This part includes requirements for components, design, fabrication, assembly, erection, inspection, examination, and testing of piping.
(c) Part PL — Pipelines. This part sets forth requirements for components, design, installation, and testing of hydrogen pipelines.
It is required that each part be used in conjunction with the General Requirements section but independent of the other parts. It is not intended that this edition of this Code be applied retroactively to existing hydrogen systems.
Readily available in secure PDF and printed edition.

Fifteen years after initial release of ASME Y14.5M comes the revised edition of Dimensioning and Tolerancing. This 224 page standard is divided into nine sections (see TOC below).
The Y14.5 standard is considered the authoritative guideline for the design language of geometric dimensioning and tolerancing (GD&T.) It establishes uniform practices for stating and interpreting GD&T and related requirements for use on engineering drawings and in related documents.
GD&T is an essential tool for communicating design intent — that parts from technical drawings have the desired form, fit, function and interchangeability. By providing uniformity in drawing specifications and interpretation, GD&T reduces guesswork throughout the manufacturing process — improving quality, lowering costs, and shortening deliveries.
Now, a consensus committee of experts has revised Y14.5 for 21st-century applications. Important changes address: concept of feature of size; datum references and degrees of freedom; composite position tolerances; surface boundaries and axis methods of interpretation; profile tolerances; and symbology and modifiers tools. Additionally, the subject matter has been restructured for better readability, with profile, orientation, and form now in separate sections, and material within sections reorganized.
This standard is available in both printed edition and PDF edition.
Section 1 – Scope, Definitions and General Dimensiong
Section 2 – General Tolerancing and Related Principles
Section 3 – Symbology
Section 4 – Datum Reference Frames
Section 5 – Tolerances of Form
Section 6 – Tolerances of Orientation
Section 7 – Tolerances of Location
Section 8 – Tolerances of Profile
Section 9 – Tolerances of Runout
In addition to these nine sections standard also contains five nonmandatory appendices:
Appendix A – Principal Changes and Improvements
Appendix B – Formulas for Positional Tolerancing
Appendix C – Form, Proportion and Comparison Symbols
Appendix D – Former Practices
Appendix E – Decision Diagrams for Geometric Control
