Bekaatherm piping systems are backed by German SKZ, ISO 15874, CE and WRAS, the certifications that clear customs, win tenders, and prove drinking-water safety. Made in Türkiye, exported to 118+ countries, built on 30+ years of manufacturing.
We supply certified piping wholesale to importers, distributors, contractors and OEM brands, not single-item retail. Certificate numbers are available on request.
For pipe, certification isn’t a marketing badge, it’s the difference between goods that clear and goods that sit in port. Miss the wrong certificate and an importer stalls at customs, a contractor gets rejected at inspection, and a tender bid is disqualified before price is even discussed. Bekaatherm carries the four certifications the market asks for most, German SKZ, ISO 15874, CE and WRAS, so your paperwork is covered before the container ships, not discovered after.
Every purchase of piping crosses at least one compliance gate before it earns a single lira of margin. The customs officer wants a conformity mark. The third-party inspector wants proof the product was actually made the way the datasheet claims. The tender committee wants a document set it can staple to your bid. The consulting engineer on a hospital or housing block wants written evidence the material touching drinking water is safe. Each of those gates has a different owner and a different document, and a container held at any one of them costs demurrage, delays the project, and puts the next order at risk.
A single Turkish manufacturer carrying all four certifications lets you clear every gate from one document set instead of chasing PDFs across three or four factories. That is the practical value of certification: not the logo on the box, but the paperwork that keeps your goods moving and your bid alive.
| Where certification decides the outcome | Who checks it | What it covers | Bekaatherm evidence |
|---|---|---|---|
| Customs clearance | Customs authority | EU & CE-recognizing markets | CE marking (docs on request) |
| Inspection & QC sign-off | Third-party / SGS-type inspector | Product conformity & quality | SKZ + ISO 15874 |
| Tender / project bids | Tender committee | Third-party compliance proof | SKZ, ISO, CE, WRAS set |

Not all certifications carry the same weight, so here’s exactly what each one proves for your goods. The headline is SKZ: our catalogue describes German SKZ as the most rigorous certification in the global piping industry, it doesn’t just test a sample, it continuously audits the production process. That’s the difference between “passed once” and “controlled every batch,” and it’s why SKZ certified PPR carries real weight with importers and project buyers.

A certificate is a statement that a product conforms to something. That “something” is a published technical standard, and a buyer who can name it can verify it independently. Below is the standards framework our piping systems are manufactured and tested to, with the issuing bodies linked so your technical team, consultant or customs broker can read the source rather than take our word for it. Certificates map onto these standards; certificate numbers are available on request.
| Standard / approval | Issuing body | What it actually specifies | Applies to |
|---|---|---|---|
| ISO 15874-1:2013 | ISO | General requirements for PP hot- and cold-water piping systems, terminology, material classification and the service-condition classes a system is designed against | All PPR pipe, fittings & valves |

| ISO 15874-3 & ISO 15874-5 | ISO | Part 3 covers fittings; part 5 covers fitness for purpose of the system, i.e. pipe and fitting tested together as an assembly rather than separately | Fittings & complete PPR systems |
| DIN 8077 / DIN 8078 | DIN, Germany | DIN 8077 sets PP pipe dimensions and the S/SDR wall-thickness series; DIN 8078 sets the general quality requirements and testing regime | PPR dimensional & quality spec |

The four approvals above cover the piping we actually extrude and mould in Türkiye every day: PPR water and heating pipe in three colours, the full fitting and valve programme, brass-insert unions, HDPE / PP compression fittings, and UPVC drainage. Here’s the range the certificates back, the same product that lands in 118+ countries.












Certifications only help you if they cover the products you’re actually buying. Bekaatherm’s certification scope spans the four systems we manufacture, from flagship PPR water and heating pipe to fittings, valves, manifolds, HDPE / PP compression fittings, and UPVC drainage, so a single supplier keeps your compliance consistent across the whole order instead of forcing you to chase documents from several factories. Ask us for the exact certificate that applies to the SKUs on your PO.

Inspectors and consulting engineers don’t sign off on a logo, they sign off on wall thickness against pressure class. Here is the real 20–63 mm outer-diameter × wall-thickness table for our three PPR structures (plain, aluminium-composite, fiber-glass composite) in PN20 and PN25, the same product the SKZ, ISO, CE and WRAS approvals back. Article numbers show the model coverage is complete, not partial.

Pipes, fittings and valves in the same order have to share the same colour, the same material and, for your paperwork, the same certification story. Our 10,000 moulds and 100% high-standard raw material mean the tee, the elbow and the brass-union in your PO come from the same certified programme as the pipe, so a customs officer or inspector sees one consistent compliance set instead of a patchwork.

A certificate is only as strong as the factory behind it. Bekaatherm’s SKZ, ISO, CE and WRAS approvals sit on top of 30+ years of PPR / PEX / PE manufacturing, a 120,000 m² plant, 1000+ staff, 10,000 molds, and 100% high-standard raw material, the same scale that lets us hold quality across 118+ countries.

Importers & DistributorsFor the Importer: Four, German SKZ, ISO 15874, CE and WRAS. Together they cover product quality, EU conformity for customs and tenders, and drinking-water safety across our PPR, fittings, PE and drainage lines. Certificate numbers are available on request, and we can email the PDFs before you order.
For the Contractor: SKZ is a German certification our catalogue calls the most rigorous in the global piping industry. It certifies product quality and continuously audits the production process, so SKZ certified PPR means factory-level control every batch, not a one-off test. That’s real reassurance for inspection sign-off and project approval.
For the OEM Brand: Yes. We supply CE for customs clearance, WRAS for potable-water sign-off, and SKZ + ISO for inspection and tenders. Certificate numbers are available on request. OEM and private-label buyers can also discuss authorized certification support for local branding and registration in their market.
For the Project Buyer: Yes. Our PPR systems carry WRAS approval, confirming materials in contact with drinking water meet UK water-fittings regulations for potable-water safety. Combined with 100% high-standard raw material and CE conformity, this covers hot and cold potable-water projects. WRAS certificate available on request.
For the Distributor: They cover the system. Our PPR fittings, brass-insert valves and manifolds come from the same certified programme as the pipe, same material, same colour, same 20–63 mm range, so SKZ, ISO and CE apply across pipe and fittings together. HDPE pipe with PP compression fittings, and UPVC drainage carry CE / ISO conformity. Ask us for the exact document per SKU.
For the Sourcing Agent: We keep certificate numbers off the public page and share them by email against a real enquiry, it protects the documents from being copied onto counterfeit goods, and it lets us send you the current, in-date PDF matched to your exact products and market. Send the SKUs and destination and we email the matching SKZ, ISO, CE and WRAS set.
