BS 7919 Cable Series: Legacy Flexible Industrial Cables and Their Modern Cross-References
A practical guide for engineers who still find “BS 7919 cable” on old drawings, maintenance lists and import documents. The BSI standard is withdrawn, so a reliable replacement must be rebuilt from the original cable’s insulation, sheath, voltage, temperature, mechanical duty and application—not from the historic number alone.
What does “BS 7919 cable series” mean today?
BS 7919 is not a current universal cable family. BS 7919:2001 was a British Standard for flexible cables rated up to 450/750 V, intended for appliances and equipment in industrial and similar environments. BSI records it as withdrawn on 1 December 2012. The phrase “BS 7919 series” is now best understood as a legacy search term that must be translated into a current construction-specific standard.
This distinction is important when a buyer requests an H07RN-F, H07BB-F, H07BQ-F, H07BN4-F, H07ZZ-F or older PVC cable “to BS 7919”. The same historic reference can point to different insulation materials, sheath compounds, voltage classes, temperature limits and environmental requirements. A technically correct replacement may therefore be compliant with a current BS EN 50525 part or BS 6004 rather than carrying BS 7919 as its primary claim.
Primary source. The BSI record for BS 7919:2001 gives the original title and withdrawn status. The current-standard references below are linked to BSI or a national standards body where the public scope is available.
BS 7919:2001 — original scope and engineering boundary
The old standard was broad enough to collect several flexible equipment-cable constructions under one British reference. That breadth is exactly why a replacement request cannot be answered by copying the number. The historic voltage limit, industrial application language and flexible-cable description are useful starting points, but they are not a complete product datasheet.
| Field | BS 7919 reference | Engineering interpretation | Status |
|---|---|---|---|
| Historic designation | BS 7919:2001 | Electric cables. Flexible cables rated up to 450/750 V for appliances and equipment intended for industrial and similar environments | source |
| BSI status | Withdrawn | BSI records withdrawal on 1 December 2012 | source |
| Historic voltage envelope | Up to 450/750 V | The old standard covered multiple flexible cable constructions; voltage alone does not identify the cable | source |
| Typical market reading | Ordinary duty 300/500 V; heavy duty 450/750 V | Published industry cross-reference; verify the exact construction and current route | derived |
| Typical application | Flexible equipment and appliance connections in industrial or similar environments | Generators, lighting, tools and machinery may require different current standards | source |
| Current-use rule | Legacy reference only | Use it to understand an old drawing or replacement request, not as the sole basis of a new compliance claim | derived |
BSI’s current BS 6004 page explains that BS 6004:2012 partially superseded BS 7919:2001 and that the conversion of CENELEC Harmonization Documents HD 21 and HD 22 led to BS EN 50525 parts. In practical terms, the old British reference was distributed into several current standards according to insulation, sheath, oil resistance, fire performance and temperature capability.
Modern replacement routes: BS EN 50525 and BS 6004
There is no single one-to-one successor for every cable once described under BS 7919. The engineer should first identify whether the cable is PVC, crosslinked elastomer, TPU, oil-resistant control, silicone or low-smoke halogen-free. Only then should the current standard part be selected.
| Current standard route | Construction covered | Published boundary | Why it matters |
|---|---|---|---|
| BS 6004:2012+A1:2020 | PVC insulated and PVC sheathed power / lighting cables | 300/500 V; maximum sustained conductor 70 °C; short-circuit conductor 160 °C for up to 5 s | National PVC construction and legacy codes such as 3183A; confirm exact table |
| BS EN 50525-2-21:2011 | Flexible crosslinked elastomer insulation with elastomer or TPU sheath | Up to 450/750 V; R types 60 °C, B types 90 °C, G types 110 °C | Common current route for rubber, PCP, EPR and TPU flexible equipment cables |
| BS EN 50525-2-11:2011 | Flexible PVC insulation and PVC sheath | Up to 300/500 V; VV 70 °C, V2V2 90 °C | Domestic-appliance flexible cable route; not automatically an industrial heavy-duty substitute |
| BS EN 50525-2-51:2011 | Oil-resistant PVC insulated and sheathed flexible control cables | 300/500 V; 70 °C; screened and non-screened types | For interconnection of manufacturing machines; confirm the exact current designation |
| BS EN 50525-2-83:2011 | Multicore crosslinked silicone rubber insulation and sheath | 300/500 V; 180 °C; fixed with mechanical protection or flexible under low mechanical stress | High-temperature route; not a general replacement for H07RN-F |
| BS EN 50525-3-21:2011 | Flexible halogen-free crosslinked cables with low smoke and corrosive-gas emission | 450/750 V; 90 °C | Special fire-performance route where the project requires LSZH behavior |
How to read the table. The values describe the public scope of the referenced current standards. They are not a Feichun product schedule. Exact core count, conductor class, nominal OD, mass, current rating, minimum bend radius, environmental tests and packing length must be released for the chosen cable.
H05 and H07 cable codes encountered in BS 7919 searches
Modern procurement documents often use CENELEC harmonised codes instead of the old British number. Eland’s published BS 7919 cross-reference lists common routes such as H05RR-F, H07RN-F, H07RN8-F, H07BB-F, H07BQ-F, H07BN4-F and H07ZZ-F. These are useful search terms, but each code still needs to be checked against the actual product datasheet and destination-market requirements.
| Harmonised code | Market description | Technical reading | Confirm before release |
|---|---|---|---|
| H05RR-F | Ordinary-duty rubber cable | 300/500 V family reference; rubber insulation and sheath | Verify current EN 50525-2-21 product file |
| H05BB-F | Ordinary-duty heat-resistant elastomer cable | 90 °C product family reference | Verify conductor, sheath and temperature code |
| H07RN-F | Heavy-duty flexible rubber cable | 450/750 V; PCP or equivalent elastomer sheath in published cross-reference | Confirm water, oil, ozone, UV and mechanical limits |
| H07RN8-F | Heavy-duty water-resistant rubber cable | Published as water-resistant heavy-duty route | Confirm immersion / water-resistance test and installation rule |
| H07BB-F | Heavy-duty heat-resistant EPR or equivalent elastomer cable | 90 °C product family reference | Confirm exact sheath compound and current rating |
| H07BQ-F | Heavy-duty TPU-sheathed flexible cable | 90 °C product family reference | Confirm abrasion, oil, UV and bend performance |
| H07BN4-F | Heavy-duty EPR / CSP or equivalent elastomer cable | 90 °C product family reference | Confirm chemical and temperature evidence |
| H07ZZ-F | Heavy-duty low-smoke zero-halogen cable | Crosslinked polymer insulation and sheath; published LSZH route | Confirm fire classification and smoke / gas tests |
For example, H07RN-F is not simply “the new name for every BS 7919 cable”. It identifies a particular heavy-duty rubber-cable route. H07ZZ-F introduces a low-smoke zero-halogen route. H07BQ-F points toward a TPU-sheathed construction. A purchaser who needs the same current, oil, ozone, UV, water, abrasion, temperature and flexing performance must compare those fields one by one.
Construction and application differences that control the replacement
Two flexible cables can have similar outer diameters and still behave very differently. PVC may be appropriate for a 300/500 V application with ordinary mechanical demand. EPR, PCP or another elastomer may be selected for higher temperature or heavy-duty handling. TPU may be chosen for abrasion performance. LSZH construction may be required when smoke and corrosive gas emission is a project safety constraint.
Insulation
Identify PVC, EPR, crosslinked elastomer, silicone or halogen-free crosslinked compound. The insulation determines temperature, flexibility, dielectric behavior and compatibility.
Sheath
PCP, CSP, TPU, PVC and LSZH sheaths do not provide the same oil, ozone, water, UV, abrasion or flame behavior. The sheath compound must follow the site environment.
Conductor
Record copper material, stranding, conductor class, resistance and allowable flexing. “Flexible” is not a sufficient mechanical specification for a moving cable.
System duty
Separate free-hand movement, equipment connection, festoon, reeling, torsion and mining trailing duty. A historic low-voltage reference does not establish continuous dynamic life.
The same reasoning applies to Feichun replacements. An independent product is stronger when the technical file makes the equivalence visible: material stack, voltage designation, conductor resistance, temperature, current rating, bend radius, environmental tests, marking and traceability.
Replacement selection method for engineers and purchasing teams
Start with the existing cable, not with a preferred brand. Photograph or record the sheath marking, identify the number and size of cores, measure the outer diameter, inspect the sheath and confirm the voltage at the equipment. Then reconstruct the environment and movement. If the original data is missing, mark it TBC rather than filling it from a similar-looking product.
| Customer wording | Wrong shortcut | Engineer’s response |
|---|---|---|
| Old drawing says BS 7919 | Do not quote the old number alone | Record material, voltage, cores, temperature, environment, OD and movement |
| Customer asks for H07RN-F equivalent | Compare construction and current harmonised designation | Check PCP / elastomer, water and oil behavior, flexing, current rating and marking |
| Customer asks for 450/750 V | Voltage is necessary but insufficient | Confirm insulation, sheath, conductor temperature and applicable standard part |
| Customer asks for outdoor or marine use | Do not infer suitability from flexibility | Confirm UV, ozone, water, salt, oil, low temperature and mechanical tests |
| Customer asks for LSZH | Use the special fire-performance route | Confirm halogen, smoke, corrosivity and flame tests, not only the sheath colour |
| Customer asks for a replacement | Match performance, not historic printing | Issue an independent drawing and product-specific certificate package |
Port and crane note: if the cable is pulled through a festoon, wound on a drum, guided in a chain or subjected to torsion, move the project into a dedicated festoon/reeling/mining-cable specification. Do not use “BS 7919” as evidence of dynamic travel performance.
Installation, inspection and failure prevention
Legacy replacements often fail because the purchasing team matches only voltage and cross-section. In the field, the failure is usually caused by a different variable: the cable is too stiff for the bend path, the sheath is incompatible with oil, a cable designed for low mechanical stress is installed in a reel, or a PVC product is exposed to an environment intended for a rubber cable.
Before installation
- Verify the current standard, harmonised code and product marking.
- Check OD against glands, clips, chain cavities and cable entries.
- Confirm the rated voltage and conductor temperature.
- Check the minimum bend radius and whether movement is permitted.
- Confirm oil, water, UV, ozone, chemical and low-temperature requirements.
During commissioning
- Inspect the complete route for crushing and sharp edges.
- Measure continuity, insulation resistance and screen continuity where applicable.
- Observe the cable at full travel or representative movement.
- Check termination torque, strain relief and conductor identification.
- Record current, ambient temperature and initial cable condition.
Maintenance
- Inspect cuts, abrasion, swelling, hardening and flattening.
- Look for heat marks near terminals and cable entries.
- Check oil, water and chemical exposure against the released compound.
- Replace damaged cable; do not convert a sheath repair into a compliance claim.
- Keep the current product drawing with the maintenance record.
| Observed symptom | Likely mismatch | Engineering response |
|---|---|---|
| Sheath cracks | Temperature, ozone, UV or chemical range not matched | Identify the exposure and select the correct current sheath route |
| Cable becomes stiff in motion | Ordinary cable installed in a dynamic path | Check whether a dedicated festoon/reeling cable is required |
| Oil swelling | PVC or elastomer not compatible with the actual oil | Verify EN 60811-404 or relevant product test evidence |
| Water ingress | Non-water-resistant construction used in wet duty | Check water-resistance design and installation protection |
| Overheating | Current rating, grouping or conductor temperature misunderstood | Recalculate installation derating and inspect contacts |
| Excessive smoke in fire test | Legacy label used without LSZH/fire-performance evidence | Select the applicable current fire-performance standard |
Tests, certificates and Feichun manufacturing capability
A current technical file should show the transition from the withdrawn reference to the selected current standard. It should include the product designation, construction drawing, conductor and insulation data, dimensions, resistance, current rating basis, mechanical limits, environmental tests, marking, routine tests and destination-market documents.
Standard evidence
State the current BS EN 50525 part or BS 6004 route. Keep BS 7919 as the historical cross-reference, not as the only current claim.
Product evidence
Request the exact drawing, materials, OD, mass, resistance, temperature, bend radius and tests for the offered cable size.
Market evidence
Match CE, UKCA, EAC, VDE, HAR or other documents to the exact construction and destination. A certificate for another cable is not transferable.
Feichun route
Feichun can develop an independently manufactured, functionally equivalent product with its own drawing, marking, tests and traceability.
Engineered for maximum safety in demanding environments, Feichun Cable can support applicable certification routes including ATEX, IECEx, VDE, CE, UKCA, EAC and the Russian Fire Safety Certificate. The exact scope must be agreed against the actual cable construction and installation; not every certificate applies to every low-voltage flexible cable.
Independent manufacturing position. Feichun’s replacement should not copy another manufacturer’s proprietary part number or drawing. The appropriate engineering target is verified functional equivalence, documented through an independent Feichun construction, test plan, marking and certificate package.

FAQ: BS 7919 replacement questions
These answers address the questions that repeatedly appear in international cable enquiries, maintenance replacements and export project documents.
Is BS 7919 still a current standard?
No. BSI records BS 7919:2001 as withdrawn on 1 December 2012. Treat it as a legacy identification and select the current standard from the actual construction.
Is there one replacement standard?
No. PVC, elastomer, TPU, oil-resistant control, silicone and LSZH constructions follow different current routes. A one-to-one replacement cannot be assumed.
Is H07RN-F the replacement for every BS 7919 cable?
No. H07RN-F is one heavy-duty rubber route. It may be appropriate for some legacy requests, but the environment, temperature, water, oil, UV and movement must match.
Can the old number remain on the purchase order?
It may remain as a historical cross-reference, but the order should also state the current standard, harmonised code, construction, voltage, size, tests and marking.
Can these cables be used on cranes or reels?
Only when the selected product is separately designed and documented for that mechanical duty. BS 7919 itself does not prove continuous festoon, reeling, torsion or mining-trailing performance.
Can Feichun supply the replacement?
Yes. Feichun can manufacture an independently engineered functional equivalent and prepare the applicable technical and certification file for the target market.

The open fields are intentional. They prevent a withdrawn standard from being used to invent a product specification that was never confirmed.
