SASO and SAS Standards for PVC Pipes in Saudi Arabia: A Buyer's Guide
SASO, the Saudi Standards, Metrology and Quality Organization, is the regulator. SAS numbers are the individual Saudi standards SASO publishes for a specific product, for example SAS 1395 and 1396 for sewer pipe or SAS 254 and 255 for duct pipe. Knowing which SAS number applies to a product is what a tender approval actually checks.
Why Standards Compliance Matters on a Saudi Project
A government or infrastructure tender in Saudi Arabia does not simply ask for PVC pipe. It asks for pipe manufactured to a named standard, and the certificate submitted for approval has to name that same standard for the exact product line being supplied. A general compliance statement that does not cite the specific SAS number is not the same thing, and procurement teams increasingly check for the difference.
This guide explains what SASO and SAS mean, which standard applies to which product, and how to verify compliance before an order is placed. For the trust page covering 4B Factory's own certification, see SASO Approved PVC Pipes.
Which Standard Applies to Which Pipe
Different pipe types are covered by different standards. The table below sets out which SAS or other standard applies to each product line 4B Factory manufactures.
| Product | Standard | Covers |
|---|---|---|
| uPVC Duct Pipes | SAS 254 and 255 | 20 to 63 mm duct for telephone and power cable protection |
| Sewer and Drain Pipes | SAS 1395 and 1396 | 110 to 710 mm, Class 2 to 4, sewer and drainage systems |
| Watermain Pressure Pipes | SASO ISO 1452 | 50 to 315 mm, Class 4 and 5, potable and utility water pressure pipe |
| PVC ASTM Standard Pipes | ASTM D 1785 and D 2241 | Schedule 40, 80 and 120 and SDR, half inch to 8 inch |
| PVC Conduit and Duct Pipes | NEMA TC 2 EPC 80-PVC | Half inch to 6 inch conduit and duct for cable protection |
Confirm the exact standard required against the project's own tender or specification document. Standards can be updated, so verify the current version with the manufacturer at the time of order.
SASO vs SAS: What the Two Terms Actually Mean
SASO is the Saudi Standards, Metrology and Quality Organization, the government body responsible for setting and enforcing product standards in Saudi Arabia. A SAS number is not SASO itself, it is one specific standard document SASO has published and assigned a reference number to, covering one product or product family. Saying a pipe is "SASO approved" is a general claim. Saying it is manufactured to "SAS 1395" is a specific, checkable one, and it is the specific claim a tender approval process is built to verify.

Request a QuoteHow to Verify Compliance Before Ordering
- Ask for the certificate by product line. A certificate should name the specific SAS number or standard for the exact pipe being ordered, not a general company statement.
- Match the standard to the application. Confirm the standard cited actually covers the product's intended use, for example potable water versus general drainage.
- Check the certificate is current. Standards are periodically revised. Confirm the version cited is still in force.
- Keep documentation on file for the tender. Procurement approval typically requires the certificate to be submitted alongside the bid, not supplied after award.
How 4B Factory Documents Compliance
4B Factory manufactures each product line to the standard named in the table above and supplies compliance documentation on request, referenced to the specific SAS, SASO, ASTM or NEMA standard that applies to that product. Documentation is provided for tender submission and project approval.

Frequently Asked Questions
SASO is the Saudi Standards, Metrology and Quality Organization, the government body responsible for setting and enforcing product standards in Saudi Arabia, including standards for PVC and uPVC pipe.
A SAS number identifies one specific Saudi standard document published by SASO, covering one product or product family. It is a more specific and checkable reference than a general SASO approval statement.
Sewer and drain pipe is covered by SAS 1395 and 1396, applying to sizes from 110 to 710 mm across Class 2 to 4.
Duct pipe for telephone and power cable protection is covered by SAS 254 and 255, applying to sizes from 20 to 63 mm.
Ask the manufacturer for a certificate naming the specific SAS or standard reference for the exact product line, confirm it matches the application, and check the certificate reflects the current version of the standard.
