SIRIM-Certified HDPE Pipe & MS 1058: What It Means and How to Check Yours
Quick Summary
If you’re buying HDPE pipe for any project that connects to a public water supply – or any job a consultant or local authority signs off on – you’ll keep seeing one word: SIRIM. Non-certified pipe is cheaper, but it can get your project rejected at inspection. This guide explains what SIRIM certification and MS 1058 actually mean, why they matter, and how to read the markings on your pipe to verify it.
Learn to spot the difference between certified and non-certified pipe before your next delivery arrives.
SIRIM certification isn’t just a sticker on a pipe – it’s the difference between a project that passes inspection and one that gets rejected. For any HDPE pipe connecting to a public water supply or going through a consultant-approved project, SIRIM certification is typically non-negotiable.
Yet many buyers still don’t know what it actually means, what MS 1058 refers to, or how to verify that the pipe delivered to their site is genuinely certified. Let’s clear that up.
What Is SIRIM Certification?
SIRIM is Malaysia’s national standards and certification body. A SIRIM-certified HDPE pipe has been independently tested and licensed to confirm it meets the relevant Malaysian Standard – and that the manufacturer’s production, testing and quality-control systems consistently meet the requirements.
In other words, SIRIM certification isn’t a one-off test of a single pipe. It’s ongoing assurance that every pipe from that production line meets spec.
What Is MS 1058?
MS 1058 is the Malaysian Standard for polyethylene (HDPE/PE) pipes used for water supply. The key part for buyers is MS 1058: Part 2, which covers the pipe itself – dimensions, material, pressure ratings and performance.
When a pipe is “certified to MS 1058,” it means its diameter, wall thickness, material grade (PE80/PE100) and pressure rating have all been verified against this standard.
Why SIRIM Certification Matters
- Water authority approval: Connections to public or potable water systems generally require SIRIM-certified, standards-compliant pipe. Non-certified pipe can be rejected.
- Project compliance: Consultants and main contractors often specify SIRIM as non-negotiable. Supplying non-SIRIM pipe can mean tearing out and re-doing work.
- Genuine spec: A non-certified “PN10” pipe may not actually hold 10 bar. Certification means the pressure rating is real.
- Long-term safety: For drinking water, certification confirms the material is safe for potable use.
How to Read the Markings on Your HDPE Pipe
Every compliant HDPE pipe has a printed line running along it. Learn to read it and you can verify any delivery on the spot. It typically includes:
- Brand / manufacturer (e.g. BBB, Hansen)
- Outer diameter and wall thickness (e.g. 110mm × 6.6mm)
- Material grade (PE80 or PE100)
- Pressure rating / SDR (e.g. PN10 / SDR17)
- Standard reference (e.g. MS 1058: Part 2)
- SIRIM licence mark / number
- Production date and batch/shift code
Red flag: If the SIRIM mark, MS number, or pressure rating is missing from the print line, treat it as non-certified until proven otherwise.
SIRIM vs Non-SIRIM: When Is Non-SIRIM Okay?
Non-SIRIM pipe is legal and cheaper, and it’s fine for non-critical, non-regulated uses – temporary site water, some private irrigation, drainage where no authority approval is needed. But for anything connecting to public water, anything inspected, or anything you want to last, SIRIM-certified is the safe choice.

Frequently Asked Questions
How do I know if my HDPE pipe is SIRIM-certified?
Check the printed line along the pipe. A certified pipe shows the SIRIM licence mark, the MS 1058 standard reference, plus the size, grade and pressure rating. If those are missing, it’s likely non-certified.
Is non-SIRIM HDPE pipe illegal?
No, it’s legal to sell and use for non-regulated applications. But it usually can’t be used where water authority approval or project compliance is required.
Does SIRIM certification apply to both PE80 and PE100?
Yes. Both grades can be SIRIM-certified to MS 1058. See our PE80 vs PE100 guide for a full comparison.
