Commission Delegated Regulation (EU) 2019/1342 of 14 March 2019 supplementing Regulation (EU) No 305/2011 of the European Parliament and of the Council by establishing classes of performance in relation to air permeability for rooflights of plastics and glass and roof hatches (Text with EEA relevance.)

• CELEX: Delegated Regulation (EU) 2019/1342
• Articles: 3

Article 1

Classes of performance in relation to air permeability for rooflights of plastics and glass and roof hatches, as set out in the Annex, are established.

Article 2

This Regulation shall enter into force on the twentieth day following that of its publication in the Official Journal of the European Union .

ANNEX

Classes of performance in relation to air permeability for roof lights of plastics and glass and roof hatches

Class

Lower limit value of Internal Pressure

(4 Pa)

Higher limit value of Internal Pressure

(100 Pa)

Air permeability

(in m 3 /(h.m))

A  ( *1 )

< 1,4

< 12

B

≥ 1,4

≥ 12

C

≥ 6

≥ 50

Note: The boundaries of the classes used in this Table may be derived from the following formula:

Where:

Q

is the leakage rate in m 3 per hour, per linear m rooflight perimeter during a test under internal pressure

P

is the internal pressure during a test (in Pa)

Q 100

is the leakage rate in m 3 per hour, per linear m rooflight perimeter at an internal pressure of 100 Pa

( *1 )   In case of class A, in addition to declaring the class, the worst measurement of all pressure steps shall also be declared using the following template: Class A ( internal pressure (100Pa), assessed leakage rate ).
