European Committee for Electrotechnical Standardization (CENELEC)

Overview & Scope

European Norms (EN) define construction, security, and fire performance standards across Europe. Under the Construction Products Regulation (CPR), communications cables installed in buildings must carry specific fire hazard ratings.

Critical Verification & Testing Standards

1

EN 50399 (Flame spread, heat release, and smoke production measurements)

2

CPR Fire Classification Tests (ratings ranging from Aca to Fca, with B2ca and Cca being standard for data centers)

3

Smoke density (s1/s2/s3) and acidity (a1/a2/a3) testing

Standard Compliance Applications

  • Public infrastructure building installations
  • High-density server room risers and pathways
  • Hyperscale and enterprise facility cabling
