If a part fails and the drawing was incomplete, PDS-1.1-2013 provides the basis for how the part have been interpreted. Reducing Shop Floor Chaos:
The "2013" in ASME PDS-1.1-2013 refers to the edition of the ASME BPVC. While newer editions exist (2015, 2017, 2019, 2021, 2023), the 2013 edition remains highly relevant for several reasons: asme pds-1.1-2013 pdf
In the 2013 revision era, the industry was moving aggressively toward zero emissions. PDS-1.1 reflects this by providing specific guidance for sealing chambers. It standardizes the dimensions to accommodate sophisticated mechanical seals, including Arrangement 2 (dual pressurized) and Arrangement 3 (dual unpressurized) seals. The standard moves away from the restrictive "stuffing box" geometry of older pumps, favoring the enlarged If a part fails and the drawing was incomplete, PDS-1
Its primary purpose is to act as the "default" rulebook. If a drawing or CAD model doesn't explicitly state which dimensioning and tolerancing standards to apply, ASME PDS-1.1-2013 provides the legally and technically binding defaults to prevent misunderstandings between designers and manufacturers. Key Areas Covered The standard acts as a bridge for: Dimensioning & Tolerancing: If a drawing or CAD model doesn't explicitly
When a drawing lacks a stated drawing standard, it must be interpreted in accordance with ASME PDS-1.1–2013.
This document is not intended as a gaging standard. It is primarily a documentation standard. For gaging, it references ASME Y14.43. Legacy Alert: 2013 vs. 2023
To understand the importance of PDS-1.1, one must understand the landscape of pump standards prior to its release.
