The regulation in simple terms
Pipes can look similar while doing very different jobs: carrying hot water, draining wastewater, protecting electrical cables or supplying gas. This regulation addresses covered pipes and their fittings used in buildings and facilities.
Choose the evidence by material and intended service, not diameter alone. A pipe suitable for drainage is not automatically suitable for hot water or gas.
Does this apply to my product?
Article 2 covers hot- and cold-water, wastewater, electricity and gas installation pipes used in buildings and facilities, including fittings and accessories. It excludes water pipes and accessories used in firefighting systems. Compliance does not replace Saudi Building Code requirements.
What does this mean for you?
- Identify the conveyed medium or electrical-protection use, material and service conditions before selecting the standard.
- Treat fittings, joints and accessories as part of the product review, not an afterthought.
- Keep reports and conformity documents traceable to the actual models and dimensions supplied.
An everyday example
A contractor has a plastic drainage pipe and a similarly sized hot-water pipe. Matching diameters do not prove equivalent temperature, pressure or joint performance. Specify the intended service and review the evidence for that exact pipe and fitting system.
Which products are covered?
These examples illustrate the applications described in the regulation and Annex 1. Exact material, product type and use determine the applicable requirements.
| Product category | Examples | What to check |
|---|---|---|
| Water supply pipes | Covered plastic and metallic hot- or cold-water pipes | Identify material, dimensions, pressure and temperature application. |
| Drainage and wastewater | Covered drainage and sewer pipe systems | Identify pressure or non-pressure service, wall construction and joints. |
| Gas installation pipes | Covered pipes and fittings for gas networks in buildings and facilities | Identify gas application, material, service conditions and joint system. |
| Electrical installation pipes | Covered pipes used for electrical installation networks | Identify cable-protection use, material and the relevant standard. |
| Fittings and accessories | Covered bends, connectors and other pipe-system accessories | Confirm compatibility and the actual fitting models covered by evidence. |
Product examples are not a complete classification. Read the official text and confirm the applicable scope before making an application.
Check the boundaries
Water pipes and accessories for firefighting systems are excluded. Do not assume a generic pipe report covers every medium, pressure, temperature, material or fitting. Building design, installation and other applicable requirements still need review.

How to get started
Use these practical steps to begin. The exact documents and tests depend on your product.
Provide a model and size list, material grade, intended medium, service conditions, wall thickness, joint type and photographs or drawings.
Collect manufacturer details, relevant pipe and fitting reports, marking information, the supplier declaration and risk assessment. Identify any existing Quality Mark licence.
Confirm the current classification, product standard and assessment route before testing or shipping; ensure supplied fittings and installation instructions match the documented system.
Does the same nominal diameter mean two pipes are interchangeable?
No. DN is a nominal size reference, not a complete specification. Material, wall thickness, dimensions, pressure and temperature class, end connection and intended service must also be checked.
Technical details and references
For a closer review, these notes point to the relevant provisions in the edition linked below.
Type 3 and the technical file
Article 6 specifies conformity certification by a SASO-accepted body under Type 3 in ISO/IEC 17067 and lists the supplier declaration and risk assessment. Article 6.5 recognizes covered pipes holding the Saudi Quality Mark or equivalent as meeting the regulation; verify the actual licence scope and current requirements.
Article 6; assessment scheme and declaration annexes.
Materials, dimensions and environmental controls
Article 4 links technical requirements to Annex 1 and requires an effective factory environmental management system, recognizing ISO 14001 for that requirement. The metrology provisions require SI units and the adopted nominal-diameter series, rather than a simple soft conversion from imperial dimensions.
Article 4.2–4.3; definitions in Article 1.
Evidence by service and handling
Use the relevant product standard for the material and application; Annex 1 lists distinct pipe and fitting standards. Article 4.4 covers safe storage, packaging and transport, while Article 5 requires clear, durable and substantiated information, warnings and instructions.
Articles 4.4–5; Annex 1.
