Certifications & Licences

For drinking water networks in Iran, the document that actually decides whether a pipe may be used is the mandatory standard mark licence for that specific application — not a management system certificate. For gas, the standard mark is an incentive (voluntary) one and sits alongside qualification with the National Iranian Gas Company. The tables below give both, each with its number, issuing body and exact scope, so any of them can be verified independently.

Standard mark licences

These are issued by the Iranian National Standards Organization: two mandatory licences — INSO 7607 for lateral irrigation since 1380 (2001), and INSO 14427-2 for pressure water supply, sewerage and drainage since 1390 (2011) — and one incentive (voluntary) licence, INSO 11223 for gas, since 1391 (2012). Each covers only the application named in its scope. A water supply licence is not an authorisation to produce gas pipe, and the reverse is equally true.

Management system certificates

These describe how the factory is run, not whether one particular pipe conforms. ISO 9001 says the production and control process is documented and audited; conformity of a given pipe to its application standard is shown by the standard mark licence and the batch test report.

Sector approvals

Registration and operating licence

Licensed annual capacity

The industrial operating licence sets a permitted annual capacity per product. This is the licence ceiling, not output in any particular year.

Awards and commendations

Alongside the licences, the factory has been recognised by government bodies over two decades. The national titles, newest first: top national cooperative from the Ministry of Cooperatives, Labour and Social Welfare (1405, 2026); commended cooperative at national level from the same ministry (1397); national model quality unit and superior product quality for polyethylene pipe from the Iranian National Standards Organization (both 1393); and model customer of the National Petrochemical Company (1381). The one that carries most weight for a pipe buyer is the Iranian National Standards Organization's "model quality unit" award — national in 1393 and provincial in 1388, 1390, 1395, 1396 and 1397. Provincial model industrial unit (1384–1388 and 1397), top provincial cooperative (1388, 1392, 1398 and 1399) and provincial model quality control manager (1391) complete the list. A title repeated across consecutive years says something a single plaque does not: that quality held up across successive inspections.

The archive holds 48 plaques. The table lists the 27 whose year and issuing body are printed on the document and legible. The rest are deliberately absent — a year inferred from a filename is not a date, and a second scan of the same plaque is not a second award. Seven further titles — model industrial unit 1385 to 1388, top provincial cooperative 1388 and 1392, and model quality control manager 1391 — appear in the company's official catalogue but their plaques are not in the archive; the table marks them as such.

How to verify these documents

• Standard mark licences: through the Iranian National Standards Organization, using the licence number
• ISO 9001: through the SGS certificate directory, using CH08/0870
• QMS certificates: with the certificate number, through the issuing body
• Trademark: through the Intellectual Property Center, using registration 370560
• For each shipment, request the test report for that production batch separately
