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 BSI records it as withdrawn on 1 December 2012.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 \u201cBS 7919 series\u201d is now best understood as a legacy search term that must be translated into a current construction-specific standard.<\/blockquote>\n <p>This distinction is important when a buyer requests an H07RN-F, H07BB-F, H07BQ-F, H07BN4-F, H07ZZ-F or older PVC cable \u201cto BS 7919\u201d. 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.<\/p>\n <div class=\"cards\">\n <div class=\"card red\"><div class=\"value\">Withdrawn<\/div><div>BS 7919:2001 is recorded by BSI as withdrawn on 1 December 2012.<\/div><\/div>\n <div class=\"card\"><div class=\"value\">450\/750 V<\/div><div>Historic umbrella voltage boundary; it does not identify insulation or mechanical duty.<\/div><\/div>\n <div class=\"card gold\"><div class=\"value\">Multiple routes<\/div><div>Current replacement depends on PVC, elastomer, TPU, silicone or LSZH construction.<\/div><\/div>\n <div class=\"card green\"><div class=\"value\">Own drawing<\/div><div>A modern equivalent needs independent dimensions, tests, marking and traceability.<\/div><\/div>\n <\/div>\n <p class=\"note\"><strong>Primary source.<\/strong> The BSI record for <strong><a href=\"https:\/\/knowledge.bsigroup.com\/products\/electric-cables-flexible-cables-rated-up-to-450-750v-for-use-with-appliances-and-equipment-intended-for-industrial-and-similar-environments\" target=\"_blank\" rel=\"nofollow noopener\">BS 7919:2001<\/a><\/strong> gives the original title and withdrawn status.

Treat it as a legacy identification and select the current standard from the actual construction.<\/p><\/div>\n <div class=\"box\"><h3>Is there one replacement standard?<\/h3><p>No. PVC, elastomer, TPU, oil-resistant control, silicone and LSZH constructions follow different current routes. A one-to-one replacement cannot be assumed.<\/p><\/div>\n <div class=\"box\"><h3>Is H07RN-F the replacement for every BS 7919 cable?<\/h3><p>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.<\/p><\/div>\n <div class=\"box\"><h3>Can the old number remain on the purchase order?<\/h3><p>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.<\/p><\/div>\n <div class=\"box\"><h3>Can these cables be used on cranes or reels?<\/h3><p>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.<\/p><\/div>\n <div class=\"box\"><h3>Can Feichun supply the replacement?<\/h3><p>Yes. Feichun can manufacture an independently engineered functional equivalent and prepare the applicable technical and certification file for the target market.<\/p><\/div>\n <\/div>\n <p class=\"formula\">FAQ specification example\nLegacy reference: BS 7919:2001 \u00b7 current route: [BS 6004 \/ BS EN 50525 part]\nharmonised code: [H07RN-F \/ H07ZZ-F \/ other] \u00b7 cores: [number] \u00b7 cross-section: [mm\u00b2]\nU\u2080\/U: [value] \u00b7 conductor temperature: [value] \u00b7 insulation \/ sheath: [materials]\ninstallation: [equipment \/ generator \/ lighting \/ machine \/ festoon \/ reel]\nenvironment: [oil \/ water \/ UV \/ ozone \/ low temperature \/ LSZH]\nrequired evidence: drawing, OD, mass, resistance, current basis, bend data,\ntests, marking, inspection plan and destination certification scope<\/p>\n <p>The open fields are intentional.
