Full title and description

ISO 10423:2003 — Petroleum and natural gas industries — Drilling and production equipment — Wellhead and christmas tree equipment. Specifies requirements and recommendations for design, performance, interchangeability, materials, testing, inspection, marking, handling, storage, shipment, purchasing, repair and remanufacture of wellhead and Christmas tree equipment used in the petroleum and natural gas industries.

Abstract

Defines the equipment types covered (casing‑head housings, spools, tubing heads, connectors and fittings, casing and tubing hangers, valves and chokes, loose connectors, actuators, hubs, ring gaskets, running/testing tools, wear bushings, etc.), service conditions (pressure, temperature, material class), and five Product Specification Levels (PSL 1–5) to establish different technical quality requirements. The standard excludes field use, field testing and field repair.

Scope

Applies to the specification, design and testing of wellhead and Christmas tree equipment for use in oil and gas drilling and production. It sets out service condition definitions (pressure/temperature/material class), dimensional and functional interchangeability, classification of components by Product Specification Level (PSL), and requirements for manufacture, testing (including hydrostatic and NDE where applicable), inspection, marking, handling and documentation. It does not cover field use, field testing or field repair activities.

Key topics and requirements

• Performance and dimensional/functional interchangeability requirements for wellhead and tree components.
• Design requirements for pressure-containing and pressure-regulating parts (corpora, hangers, connectors, valves, chokes, etc.).
• Material selection and material class definitions tied to service conditions (pressure/temperature/environment).
• Manufacturing, welding, heat treatment and acceptance testing (hydrostatic tests, NDE) requirements.
• Inspection, marking, handling, storage, shipment and quality documentation.
• Five Product Specification Levels (PSL 1–5) defining progressively stricter technical quality requirements and testing/verification obligations.
• Guidance (non‑mandatory) for selecting an appropriate PSL for the purchaser’s application.

These topics reflect the standard’s core content and the PSL framework used to match product quality to application criticality.

Typical use and users

Used by wellhead and Christmas tree equipment manufacturers, designers and engineers, procurement and quality assurance teams, testing and inspection organizations, offshore/onshore operators, and regulatory or certification bodies involved in oil & gas production equipment specification and acceptance. It supports purchasers and manufacturers in defining technical purchase specifications and acceptance criteria.

Related standards

ISO 10423 has later editions and related documents. It was revised in later editions (subsequent editions and harmonized regional/sector adoptions exist — e.g., later ISO 10423 editions and regional EN/BSI adoptions). Subsea and completion standards (for example the ISO 13628 series) and industry standards such as API 6A cover overlapping subject matter and are commonly used together with ISO 10423 requirements. Users should consult the most recent ISO 10423 edition for current requirements.

FAQ

Q: What is this standard?

A: ISO 10423:2003 is an international standard that specified requirements for wellhead and Christmas tree equipment used in petroleum and natural gas drilling and production. It defines equipment types, service conditions and quality levels (PSL).

Q: What does it cover?

A: It covers design, materials, dimensional and functional interchangeability, testing (including hydrostatic and NDE where required), inspection, welding, marking, handling, storage, shipment, purchasing, repair and remanufacture of wellhead and Christmas tree equipment. It excludes field use, field testing and field repair.

Q: Who typically uses it?

A: Manufacturers, designers, QA/QC and inspection teams, procurement specialists, operators (onshore/offshore), and certifying/regulatory bodies in the oil & gas sector.

Q: Is it current or superseded?

A: The 2003 edition is withdrawn and later revised; consult the ISO catalogue for the current ISO 10423 edition (later revisions and a 2022 version are indicated in ISO lifecycle records). For design and procurement use, always reference the most recent edition or the purchaser‑specified edition.

Q: Is it part of a series?

A: It is part of the suite of standards maintained by ISO/TC 67 (petroleum and natural gas industries) and is commonly used alongside related standards such as the ISO 13628 subsea systems series and industry standards like API 6A.

Q: What are the key keywords?
