BS 8524 Scope
BS 8524-1:2013 Active fire curtain barrier assemblies-Part 1: Specification
This part of BS 8524 specifies requirements for the design, testing and classification of active fire curtain barrier assemblies, for installation in accordance with the recommendations of BS 8524-2. It covers the reliability and durability, fire resistance, smoke containment and impact resistance performance of the active fire curtain barrier assemblies, their control devices and ancillary equipment.
The requirements within this part of BS 8524 are applicable to active fire curtain barrier assemblies of any material that are designed to provide fire resistance.
This part of BS 8524 does not cover active smoke barriers, or active fire curtain barrier assemblies that are used only for fire and smoke control as fire doors.
NOTE 1 Smoke barriers, used solely for smoke control, are covered by BS EN 12101-1. Such smoke barriers are not considered to be active fire curtain barrier assemblies within the scope of BS 8524.
NOTE 2 Guidance on fire doors is given in BS 8214. Requirements for fire doors for fire and smoke control are given in EN 16034.

Fire safety and protection are more prevalent than ever before. There is a huge push on competency and compliance for the installation and products in the fire industry in 2022, following tragic recent events such as Grenfell.
Just like a plumber would need to showcase that they are competent to service a boiler, the demand for fire protection installers to show they are competent is essential.
BS 8524 PART 1 AND PART 2
BS 8524 is the first unique product standard in the world relating solely to active fire curtain barrier assemblies. The standard is split into two parts; BS 8524-1 (Specification) and BS 8524-2 (Code of practice for application, installation and maintenance).
Both parts provide comprehensive guidance to specifiers, manufacturers, installers, building inspectors and buyers, with information about the manufacturing of a fire curtain product, how it is installed and its ongoing service and maintenance.
BS 8524 is the only global fire curtain standard and supersedes PAS 121: 2007. Third-party certification is required for this standard, and both parts are important to consider. The certification provides certainty to end-users and building occupiers that the product has passed in-depth third-party testing against a set of strict standards and criteria.
The former fire curtain specification, PAS 121:2007, was overtaken by BS 8524 in April 2013. BS 8524 covers the entire system, and to be fully compliant fire curtains must have passed all required testing.
BS8524 PART 1
Part 1, the specification for active fire curtain barriers, provides information, requirements and guidance on how to test for each aspect of the standard. It can only be achieved if all nine annexes, of which it comprises, are satisfied and approved by a third-party certification body. Annex G, for example, outlines the testing method for motor operation, which involves placing it at elevated temperatures, and at maximum loads following a prescribed timeline heat curve for a specified number of cycles.
BS8524 PART 2
Part 2 provides a code of practice for the application, installation and maintenance of fire curtains. The annexes it consists of include guidance on installation checklists, commissioning, as well as maintenance. For example, the comprehensive Inspection Checklist in Annex F details the requirement for the curtain to descend into a ‘closed’ position at the required descent speed when the power cable to the control panel is disconnected. This proves the gravity fail-safe mechanism works and can maintain the required descent speed as dictated by the standard.
A GUIDE TO ANNEXES
BS 8524-1 is a rigorous and complex test standard and is specific only to fire curtain barriers. It, therefore, provides less ambiguity between this standard and other passive fire protection product standards e.g. BS EN 1634-1
The numerous annexes (A to I) and references that MUST be completed to be fully compliant with BS 8524-1 include the following:
·Annex A (normative) Overlapping multiple barriers
·Annex B (normative) Order of testing
·Annex C (normative) General requirements for testing
·Annex D (normative) Test method for barrier assembly reliability and response time and the durability of materials
·Annex E (normative) Test method for the durability and reliability of alternative or additional motors
·Annex F (normative) Calculation of ambient temperature smoke leakage
·Annex G (normative) Test method for the reliability of motor operation at elevated temperatures
·Annex H (normative) Test method for ancillary and optional equipment
·Annex I (informative) Typical product performance summary
THIRD-PARTY APPROVAL SCHEME
BS 8524 is designed to be a fully ratified and audited product, installation and service scheme. The standard ensures through periodic audits that the provenance of the product’s components is the same as those that were tested originally. Installations are also picked at random for site visits for compliance with best practices.
International Fire Consultants (IFC) offer a UKAS approved BS 8524 full third party certification scheme through IFC Certification
It is important that both BS 8524-1 and BS 8524-2 are supported by the third party scheme provider
Always ask the product manufacturer and installer for their BS 8524-1 and BS 8524-2 certification
ISO 21524:2021 – REQUIREMENTS FOR ACTIVE FIRE CURTAINS
ISO 21524 is the new international standard for fire curtains. This new international standard builds on many of the aspects within BS 8524-1 and BS 8524-2; enhancing some of the requirements and introducing new features such as pass doors and vision panels. There is also a new requirement to include repair patches to tears in the fabric.
The forthcoming new release of BS 8524-1 and BS 8524-2 refers to ISO 21524 for the test method of the new features and in some cases making further improvements.
