TGD 21 - UKCA / CE Marking of Operable Fabric Curtains

ASFP Technical Guidance Document - TGD 21
UKCA / CE Marking of Operable Fabric Curtains.

Current Issue: September 2023

Following the re-citing of EN 16034:2014 in the Official Journal of the European Union (OJEU) on 28 October 2016, CE marking of operable fabric curtains became Mandatory under European Union Construction Product Regulations (CPR) from 01 November 2019.

The CE marking of operable fabric curtains is based on the harmonised product standard BS EN 16034:2014 can only be applied in combination with either BS EN 14351-1:2006 + A2:20161 or BS EN 13241:2003 + A2:20162, and should be applied in instances where the scope of BS EN 16034:2014 applies.

TGD 20 - Fire Test Standards and the Construction Products Regulation in Relation to Fire Resisting Ventilation and Smoke Control Duct Work

ASFP Technical Guidance Document - TGD 20
BESA VG005
ADCAS TGD 01/20.08
Fire test standards and the Construction Products Regulation in relation to fire resisting ventilation and smoke control ductwork.

Current Issue: January 2022

Following the implementation of the construction products regulations (CPR) in July 2013, it is a legal requirement to comply with any harmonised European product standard and provide tested products covered by that standard. With regards to fire resisting ventilation and smoke control duct sections not all the required standards are published and consequently this limits what can be supplied. The purpose of this Guidance document is to provide an understanding of what these limitations are, when they will change and what can individual stakeholders do in the intervening period.

This document has been written in collaboration with the trade bodies ASFP, BESA and ADCAS to provide an industry wide position.

Current Issue: November 2017

This test method has been drafted by, a sub-group of ASFP Task Group 3 (fire-stopping) which in turn reports to the ASFP Technical Committee. It has been drafted in response to a need identified by the ASFP for a test method to evaluate the fire resistance of ‘open-state’ cavity barriers. The method is also intended to assist certification bodies to develop technical schedules allowing for the third party product certification of ’open-state’ cavity barriers.
