EN 877:2021 Certificate and Technical Downloads
KELI's published Certificate of Conformity SC-PSC-4-2026-09-20 lists cast iron pipes and cast iron fittings, models DN40–DN600, against EN 877:2021. The document states an issue date of 9 September 2026 and expiry date of 8 September 2031.
This is the scope stated in the certificate, not a stock list or a dimensional schedule for every model. Confirm the selected product, coating, dimensions and project acceptance documents before ordering.

Angles, Model Numbers and Drawing Dimensions
The archived KELI catalogue includes bends at 15°, 30°, 45°, 68° and 88°, single branches at 45°, 68° and 88°, and separate drawings for double bends, long-spigot bends, double branches, reducers and access fittings. Confirm each size and variant against its drawing rather than assuming every angle is available in every DN.
| BOQ description | Catalogue product number | Drawing dimensions (mm) | Reference kg/piece |
|---|---|---|---|
| Bend 45° DN100 | 011010045 | X = 70 | 1.6 |
| Bend 88° DN100 | 011010088 | X = 110 | 2.1 |
| Single branch 45° DN100 × DN50 | 015010005045 | X1 / X2 / X3 / L = 35 / 165 / 165 / 200 | 2.5 |
| Single branch 45° DN100 × DN100 | 015010010045 | 70 / 205 / 205 / 275 | 4.2 |
| Single branch 68° DN100 × DN50 | 015010005068 | 55 / 110 / 100 / 155 | Confirm schedule |
| Single branch 88° DN100 × DN50 | 015010005088 | 94 / 76 / 105 / 170 | Confirm schedule |
Model numbers and dimensions: archived catalogue, printed pages 26–29. Weights: April 2026 product schedule, matched by family, angle and DN. These are reference selections; obtain the current drawing revision for approval. Bend X is the centre-line intersection to end-face dimension. Branch dimensions must be read with the corresponding catalogue drawing, not interpreted as pipe outside diameters.
Joint interface sizes
The pipe-side catalogue OD references for matching socketless joints are DN50: 58 mm, DN70: 78 mm, DN75: 83 mm, DN100: 110 mm, DN125: 135 mm, DN150: 160 mm and DN200: 210 mm. Verify the fitting sealing zone, actual OD/tolerance and coupling clamping range together. See the pipe dimensional reference table; DN250/DN300 need the noted drawing checks.
How to Match a BOQ to a KELI Model
- Keep the original BOQ line number, description, quantity and unit.
- Identify the product family and exact angle, then main DN and branch DN in that order.
- Identify the variant: standard bend, long spigot, access fitting, reducer or double branch.
- Match the catalogue product number and drawing dimensions, including joint OD and sealing-zone requirements.
- Confirm coating, drawing revision, inspection documents and any substitution before quotation approval.
Example: “45° single branch, DN100 × DN50” maps to catalogue 015010005045, with X1/X2/X3/L = 35/165/165/200 mm and reference mass 2.5 kg. A BOQ requesting 90° or DN80 needs a clarification; do not silently substitute the catalogue 88° or DN75 entry.
Fitting coating and inspection file
The archived SML catalogue describes epoxy resin powder coating at approximately 60–100 μm. Confirm the current specification for the ordered fitting. Request the approved drawing, dimensions/angles and sealing-zone inspection record, coating thickness/adhesion records, product identification and applicable material/type-test evidence. Inspection acceptance must reference the agreed standard edition.
