Buyer guide to H05VV-F, H03VV-F and H03VVH2-F flexible PVC cables
Compare H05VV-F with H03VV-F and H03VVH2-F by application, construction, published table values, standard reference and document scope. This guide sets out the information a buyer should include in an RFQ to a manufacturer or supplier.

Products and families referenced
Start with the product code
H05VV-F, H03VV-F and H03VVH2-F appear within the same flexible PVC cable family, but a purchase decision should not be made from the family name alone. The CMK product records give each designation its own construction, application wording and technical table. Confirm the requested code, number of cores and cross-section before requesting price. The manufacturer or supplier quotation should match the code on the product page exactly.
The H05VV-F record shows 300/500 V. The H03VV-F and H03VVH2-F rows are shown as 300/300 V. These entries do not establish automatic equivalence between products or sizes. Compare the code, nominal voltage, core arrangement, cross-section and relevant data sheet on one controlled line. Do not fill an unpublished property by copying it from a similar cable.
Read construction and application together
All three records identify a Class 5 flexible copper conductor, PVC insulation and PVC sheath. This defines the basic construction; it does not by itself establish outdoor use, oil resistance, a temperature range, bending radius or current-carrying capacity. A technical review should use the construction and application statements that are actually present in the source record.
The published application wording covers enclosed and dry locations where mechanical stresses occur, household appliances, and steamy or humid environments. It is not a blanket approval for every installation method. If the project requires outdoor use, continuous movement, embedding or a specific environmental property, state that requirement in the RFQ and obtain code-specific confirmation from the manufacturer.
Compare the technical table on like-for-like lines
The H05VV-F table lists options from 2x0.75 through 5x4. For example, 2x0.75 is listed with 0.6 mm insulation, 0.8 mm sheath, 6.4 mm average outside diameter, 26 Ω/km resistance and approximately 55 kg/km. For 3x1.5, the published values are 0.7 mm, 0.9 mm, 8.2 mm, 13.3 Ω/km and 103 kg/km respectively.
The H03VV-F table includes 2x0.50, 2x0.75, 3x0.50, 3x0.75, 4x0.50 and 4x0.75. H03VVH2-F lists 2x0.50 and 2x0.75, with average dimensions of 3.10x4.90 mm and 3.30x5.40 mm. Both designations show 0.5 mm insulation and 0.6 mm sheath for these entries. Compare the same core count and cross-section, and keep the source notation unchanged.
Record the standard and voltage
The standard field for the H05VV-F, H03VV-F and H03VVH2-F product records is BS EN 50525-2-11:2011. A standard reference in the product record does not mean that every quoted variant has automatically been checked against every project condition. Keep the standard reference in the procurement file together with the product code, cross-section and requested document type.
The H03VV-F and H03VVH2-F technical table presents 300/300 V rows under separate designation headings. H05VV-F is presented as 300/500 V. Similar-looking product codes do not have the same voltage entry. If a supplier data sheet presents a different voltage or variant, ask for the matching product record and written clarification before treating it as equivalent.
Separate certificates from data sheets
Document review should be based on document type and product scope, not on a filename alone. The records show BASEC, TSE-HAR, DATA SHEET, CPR (CE), CPR (UKCA) and CE entries for the H03VV-F/H03VVH2-F record. H05VV-F also has data sheet, CPR (CE), CPR (UKCA), CE and TSE-HAR records. The presence of these entries does not prove that every document covers every size or designation.
A data sheet gives construction and table information; a certificate, DoP, CPR file or other conformity document has a different role. When opening a file from the Documents page, check its title, product code, scope and revision where relevant. If the scope is unclear, request written clarification from the manufacturer instead of marking the quotation as fully compliant.
Put the buying information into the RFQ
Name the known full designation in the request: H05VV-F or H03VV-F / H03VVH2-F. Add core count and cross-section, quantity, delivery terms, required delivery date and the document type needed for approval. Describe the application using the source wording where possible: enclosed and dry location, household appliance, steamy or humid environment. Copy any required standard and nominal voltage from the project specification without paraphrasing it.
Ask the manufacturer or supplier for unit or total price together with the exact product code, technical data sheet, relevant certificate or CPR file, and document scope. Make sure the quotation shows 300/500 V for H05VV-F and 300/300 V for H03VV-F and H03VVH2-F. Treat a price as technically comparable only when the size, code and documents match. Complete the check through the product page, family page, Documents area and quote request.
Close technical approval before comparing price
Before comparing quotations, match every line to the product code and technical table. Mark which record supplies the outside diameter, resistance and approximate weight for the same core count and cross-section. If a supplier data sheet differs from the source table, ask for an explanation instead of silently treating the values as interchangeable. This check reduces the risk of comparing a price for another size or designation.
Keep the product page, relevant technical data sheet, certificate or CPR file and required standard under the same product code in the final purchasing file. Do not use a similarly named document prepared for another product. Close open questions about application, voltage, size or document scope in writing before ordering. The result is a quotation that procurement can audit against one defined technical record.
