SIST EN 50525-2-71:2011 is the Slovenian adoption of EN 50525-2-71:2011 from CENELEC for thermoplastic PVC-insulated flexible flat tinsel cables. It specifies the construction, dimensions, marking and test regime for H03VH-Y cords rated 300/300 V, intended for connecting small appliances to the fixed supply.

What does SIST EN 50525-2-71:2011 specify?

SIST EN 50525-2-71:2011 applies to thermoplastic (PVC) insulated flexible flat tinsel cables for low-voltage energy use. It sets the product type, the voltage rating, the maximum conductor operating temperature, and the test and data framework used to verify the cable.

The document is organized into four clauses and three normative annexes:

Annex	What it covers
Annex A	Tests for cables to EN 50525-2-71
Annex B	General data for Type H03VH-Y
Annex C	Mechanical tests on completed cables

Clause 1 gives the scope, Clause 2 lists the referenced standards, Clause 3 points to the terms and definitions in EN 50525-1, and Clause 4 gives the construction and requirements for Flexible cables - H03VH-Y.

What are the key requirements of SIST EN 50525-2-71:2011?

SIST EN 50525-2-71:2011 defines a specific flat cable construction and then ties compliance to dimensional, electrical, mechanical and fire tests. In practice, manufacturers use it to design the cable, set inspection limits, and choose the required type tests.

Construction and cable identity

Clause 4.1 defines H03VH-Y as a two-conductor flat tinsel cable. Each conductor consists of strands or groups of strands made from flattened copper or copper alloy wires wound on a cotton, polyamide or similar thread, and the two conductors are laid parallel.

Clause 4.1 also requires PVC insulation of Type TI 2 to EN 50363-3, with grooves on both sides between the conductors to make separation easier. The cable must be marked with the CENELEC code H03VH-Y, so the product can be identified in manufacture, testing and purchasing.

Performance and conformity checks

Clause 4.2 says each cable shall meet EN 50525-1 as well as the particular requirements in this part. It also sends testing to Annex A and limits dimensions to the ranges in Annex B. For a buyer or quality manager, this is the practical checklist for acceptance: the cable must be the right construction, the right size, and within the stated electrical limits.

Electrical, dimensional and material testing

Annex A brings together the tests used to verify the cable. It covers conductor resistance, voltage test at 2 000 V, insulation resistance at 70 °C, long-term resistance of insulation to d.c., absence of faults in insulation, constructional checks, thickness of insulation, overall diameter, material tests on the insulation, impact at - 5 °C, and the fire test for vertical flame propagation on a single insulated wire or cable.

This matters because the standard does not rely on one result alone. A cable is checked as a complete product, so design, materials and workmanship all have to work together.

Mechanical endurance of completed cables

Annex C gives the bending test and the snatch test for completed cables. The bending test requires 60 000 bending cycles and no interruption of current during the test; afterward the sample must withstand a voltage test at 1 500 V between the conductors connected together and water. The snatch test also requires no interruption of current.

For production and type testing, this shows whether the finished cord can survive repeated flexing and handling without failing in service.

What terms does SIST EN 50525-2-71:2011 define?

SIST EN 50525-2-71:2011 uses the terms and definitions from Clause 3 of EN 50525-1. A few key terms and abbreviations used in this part are:

• PVC - Polyvinyl chloride, the thermoplastic insulation material used on the cable.
• U0/U - The rated voltage notation used for the cable, here 300/300 V.
• H03VH-Y - The CENELEC code used to identify this cable type.
• TI 2 - The PVC insulating compound type required by EN 50363-3.
• Small appliances - The intended end-use for the cable connection to the fixed supply.
• Fixed supply - The supply arrangement to which the appliance is connected.

Who uses SIST EN 50525-2-71:2011?

SIST EN 50525-2-71:2011 is used by cable manufacturers, test laboratories, conformity assessors, appliance makers, and purchasers who need a specified flat cord for small appliances. It is also relevant to quality managers who verify construction, marking and test compliance, and to engineers who select a cable design and define acceptance criteria.

What changed in SIST EN 50525-2-71:2011 from the previous edition?

SIST EN 50525-2-71:2011 supersedes Clause 2 of HD 21.5 S3:1994 + A1:1999 + A2:2001.

Which standards are used with SIST EN 50525-2-71:2011?

SIST EN 50525-2-71:2011 depends on several referenced documents for materials and test methods:

• EN 50525-1 - Gives the general requirements and the common terms and definitions.
• EN 50363-3 - Specifies PVC insulating compounds, including Type TI 2.
• EN 50395 - Provides electrical test methods used for conductor resistance, voltage test and insulation resistance.
• EN 50396 - Provides non-electrical test methods used for dimensional checks and mechanical tests.
• EN 60332-1-2 - Gives the fire test for vertical flame propagation on a single insulated wire or cable.
• EN 60811-1-4 - Gives low-temperature test methods, including the impact test at - 5 °C.
• HD 516 - Gives guidance on safe use of the cables covered by this standard.

What does the SIST EN 50525-2-71:2011 document contain?

SIST EN 50525-2-71:2011 contains the construction description for H03VH-Y, the requirement list, and the test regime needed to verify the cable. Annex A brings the test plan together in a table, including the test methods and the referenced clauses in the test standards.

Annex B provides general data for Type H03VH-Y, including insulation thickness, mean overall dimensions, minimum insulation resistance at 70 °C, and maximum conductor resistance at 20 °C. Annex C gives the procedures for the mechanical tests on completed cables, including the bending and snatch tests used to check durability in use.
