You are likely to see the majority of cables between Classes Cca and Fca.  \nFire performance: high level of flammability under test and burns over 425mm.  \nTests: BS EN 60332-1-2 (basic vertical flame test by factory or lab) .  \nFSC Comment: Cables classified to Class Fca may have high levels of flammability due to the materials they are made of. For example, cables with a PE sheath that are primarily intended for external use, such as telephone or duct grade cable, could be tested and classified to Class Fca, which is perfectly acceptable when used in an appropriate environment.  \nFire performance: limited fire spread under test and burns less than 425mm.  \nTests: BS EN 60332-1-2 (by an authorised test house, known as a Notified Body (NB) or Approval Body (AB)) .  \nFSC Comment: The same basic test as Clas Fca for vertical flame proagation for a single wire or cable using a 1-kW flame. Note that this test does not measure heat release, toxic fumes or smoke.  \nCPR FOR CABLES  \nMost cables designed for permanent installation within domestic, residential and commercial buildings are subject to the Construction Products Regulation (CPR), covered by BS EN 50575. This became a legal requirement in July 2017 so it’s important you understand how to stay compliant.  \nBS EN 50575 is a regulation which brings together common classification, criteria and monitoring requirements to form seven Euroclasses. These classes have fire performance assessment processes based on BS EN 60332-1-2, BS EN 50399 and BS EN ISO 1716. There are additional tests for Smoke Production, Flaming Droplets and Acidity.  \n[www.fscables.com/cpr | sales@fscables.com](www.fscables.com/cpr | sales@fscables.com) Tel: 01727 840 841   \nSummary of Euroclass test results for CPR-rated cables  \nAdditional Classifications for Euroclasses B to D  \n\n|  | Smoke Production\u003Cbr>BS EN 50399 /\u003Cbr>BS EN 61034-2 | Flaming Droplets\u003Cbr>BS EN 50399 | Smoke Acidity\u003Cbr>BS EN 60754-2 |\n| --- | --- | --- | --- |\n| | s1a: s1 + transmittance >=80%(BS EN 61034-2)\u003Cbr>s1b: s1 + transmittance >=60% \u003C80%(BS EN 61034-2)\u003Cbr>s1: Low production & slow propagation of smoke\u003Cbr>s2: Intermediate production & propagation of smoke\u003Cbr>s3: None of the above | d0: No fall of droplets or flaming particles, timed for 1200 seconds\u003Cbr>d1 : Fall of droplets or flaming particles that persist for less than 10 seconds, timed for 1200 seconds\u003Cbr>d2: None of the above | a1: -Very low acidity (conductivity \u003C2 .5 µS/mm & pH >4 .3)\u003Cbr>a2: Low acidity (conductivity \u003C10 µS/mm & pH >4 .3\u003Cbr>a3: None of the above |\n| |  |  |  |\n| |  |  |  |\n| |  |  |  |\n\nSmoke Production: This is mandatory for Classes Dca, Cca, B2ca and measures smoke production, which is monitored during the ladder test (BS EN 50399) . There is a further, optional smoke test to BS EN 61034-2.  \nFlaming Droplets: This is an optional observation to monitor flaming droplets during the ladder test to BS EN 50399.  \nAcidity: This is an optional separate test to BS EN 60754-2 which measures the acidity of gases given off.  \nClasses A to E have to be tested by an independent authorised laboratory.  \nMost cables will fall into classes B2ca to Eca. For a cable to meet Aca, B1ca, B2ca or Cca, there also needs to be regular on-going factory audits.  \n[www.fscables.com/cpr | sales@fscables.com](www.fscables.com/cpr | sales@fscables.com) Tel: 01727 840 841   \n\n| Reaction to Fire BS EN ISO 1716 |  | FSC Comment |\n| --- | --- | --- |\n| | Does not contribute to the fire | It will be almost impossible for a cable to meet Class Aca and due to availability, they should only be specified with extreme caution. |\n| Reaction to Fire BS EN 50399 |  |  |\n| | Minimum contribution to the fire | It’s very unlikely that commonly-used cables will be classified to Class B1ca. |\n| | Combustible, low flame spread & heat release contri","cbCaidqwhbrVU18G","https://ap.wps.com/l/cbCaidqwhbrVU18G","pdf",1890939,"English","# THE CLASSES\n## CPR FOR CABLES\n## Summary of Euroclass test results for CPR-rated cables\n## Additional Classifications for Euroclasses B to D\n## Reaction to Fire test mappings\n## WHO’S RESPONSIBLE?\n## WHICH CLASS?","[{\"question\":\"What is the Construction Products Regulation (CPR) requirement for cables?\",\"answer\":\"Most cables for permanent installation in domestic, residential, and commercial buildings are subject to CPR and are covered by BS EN 50575.
