The document you are looking for is ASME PDS-1.1-2013 "Dimensioning, Tolerancing, Surface Texture, and Metrology Requirements for Drawings and Models."
This standard serves as a guide for specifying requirements on technical drawings and 3D models, particularly focusing on how to reference other ASME standards like Y14.5 (Dimensioning and Tolerancing) and Y14.36 (Surface Texture Symbols). How to Access the Paper

The standard ASME PDS-1.1-2013, titled "Dimensioning, Tolerancing, Surface Texture, and Metrology Standards—Rules for Drawings with Incomplete Reference to Applicable Drawing Standard," is a critical regulatory document for mechanical engineering and manufacturing. It serves as a "default" protocol when a technical drawing or digital model fails to specify which national or international standard it follows. Core Purpose of ASME PDS-1.1-2013
In modern engineering, drawings must be governed by specific standards (like ASME Y14.5 for GD&T) to ensure they are interpreted correctly by manufacturers and inspectors. However, many legacy or incomplete drawings omit these references. The ASME PDS-1.1-2013 standard fills this gap by defining: The document you are looking for is ASME PDS-1
Default Rules: It establishes which dimensioning and tolerancing principles apply when no other reference is stated.
Universal Application: This standard applies to drawings created in any country and covers both physical 2D drawings and 3D digital models.
Scope: It covers rules for dimensioning, tolerancing, surface texture, and the associated metrology (measurement) standards. Key Sections and Technical Focus
The standard provides a hierarchy of rules to resolve ambiguity in technical documentation:
Applicable Standards: It points to specific existing ASME standards that should be used as the default baseline, such as those within the ASME Y14 series. How to Legitimately Obtain the ASME PDS112013 PDF
Surface Texture Controls: It includes methods for specifying and interpreting roughness and waviness when symbolic methods are used without clear standard citations.
Measurement Defaults: It defines the metrology requirements necessary to verify that a part meets the geometric requirements of the drawing. Current Status: Superseded ASME PDS 1.1 : 2013 - Intertek Inform
ASME PDS-1.1-2013, "Dimensioning, Tolerancing, Surface Texture, and Metrology Standards," provides default rules for engineering drawings that lack specific standards references, reducing ambiguity in technical drawings and 3D models. It was jointly developed by ASME B46, B89, and Y14 committees to standardize global practices, though it has been superseded by the 2023 edition. For more details, visit ASME Official Store.
Given the importance of this document, you must be cautious about where you source it. Using an expired, altered, or counterfeit version can void your vessel’s ASME Stamp.
Large EPC firms (Fluor, Bechtel, KBR) often create internal “Project Data Sheets” (PDS). An administrator may have scanned an internal work instruction that references ASME 2013 rules and labeled the file “ASME_PDS_112013.pdf” as a local naming convention. When that PDF leaked to the open web, search engines indexed it as a genuine standard. You are chasing a shadow of a company’s file server.
The standard mandates that manufacturers provide an instruction manual that includes:
