Full title and description

ASME Y14.37-2019 — Product Definition for Composite Parts. This ASME Y14 series standard establishes requirements, exceptions and additional practices for defining composite parts on engineering drawings and in product definition data where existing Y14 documents do not fully apply.

Abstract

ASME Y14.37-2019 provides rules and conventions for the definition and documentation of composite parts (inseparable assemblies of composite materials that may include non-composite materials). It clarifies how existing Y14 drawing and model-based definition standards are to be applied to composite parts, and specifies additional or exception requirements needed to convey ply, layup and related composite information consistently across design, manufacturing and inspection activities.

Scope

This standard applies to the product definition (drawings and model-based definition) of composite parts where existing ASME Y14 standards (for example general drawing practices, dimensioning and tolerancing, and digital product definition) do not specifically address composite-specific requirements. It defines what constitutes a composite part for Y14 purposes, and provides rules for communicating ply and layup data, material and ply-sequence notation, exceptions to standard Y14 conventions, and recommended practices to ensure interoperability among design, manufacturing and inspection stakeholders.

Key topics and requirements

• Definition and identification of composite parts and inseparable composite assemblies.
• Notation and presentation of ply stacks, ply orientation and ply sequencing on drawings and models.
• Exceptions and additions to general Y14 drawing conventions specific to composite materials.
• Guidance for integrating composite part definition with model-based practices and downstream data exchange.
• Practices to support interchangeability and clearer communication across supply chain and inspection processes.

Typical use and users

Intended users include design and drafting engineers, manufacturing and production engineers, tooling and gage designers, quality/inspection personnel, CAD/CAM/CAE specialists, and educators—especially in aerospace, automotive, medical devices, precision instruments and other industries that design and produce composite parts. The standard is used to prepare composite part drawings, specify ply tables/layups, and to align drawing/model information with manufacturing and inspection needs.

Related standards

ASME Y14.37 is part of the Y14 family (engineering drawing and product definition). It is commonly applied alongside ASME Y14.5 (dimensioning and tolerancing), Y14.41 (digital product definition/model-based definition), and other Y14 documents addressing product definition, model organization and additive manufacturing; harmonization with ISO STEP representations (ISO 10303-242) and other composite-data models is also an area of cross-reference and coordination.

Q: What is this standard?

A: ASME Y14.37-2019 is the ASME Y14-series standard that specifies how to define and document composite parts on drawings and in product definition data.

Q: What does it cover?

A: It covers the definition of composite parts, the presentation of ply/layup information, exceptions or additions to other Y14 drawing/model-based rules needed for composites, and guidance for communicating composite-specific details to manufacturing and inspection.

Q: Who typically uses it?

A: Design, manufacturing, tooling, quality and CAD/CAM/CAE personnel in industries that design and produce composite components—most notably aerospace, automotive and medical device sectors.

Q: Is it current or superseded?

A: The 2019 edition is the current ASME edition for Y14.37; it updates and supersedes the earlier (2012) edition and ASME indicates the document is on stabilized maintenance for handling change requests.

Q: Is it part of a series?

A: Yes — it is part of the ASME Y14 series for engineering drawing and product definition practices and is intended to be used in coordination with other Y14 standards (for example Y14.5, Y14.41, Y14.46, Y14.47).
