4 In terms of the New Zealand Building Code (NZBC) requirements, fre rating performance is referred to as FRR (Fire Resistance Rating) and is measured in minutes a FRR 30/30/30 means a fre rating for 30 minutes. Further explanation in this matter is provided in section of this Design Manual . J ames Hardie Fire And Acoustic System Description Each FRR system is identifed by a unique specifcation number ( ) to identify it as one of the James Hardie fre resistance rated wall systems. The explanation of specifcation numbers used are as follows.

7 This Manual is intended to assist designers in selecting a suitable James Hardie product and choose a system which will meet their performance requirements. Various sections in this Manual have been arranged to ensure quick familiarisation with James Hardie fre and Acoustic systems. Readers must also familiarise themselves with the relevant James Hardie cladding and lining product literature. Scope The fre and Acoustic systems provided in this Design Manual are suitable for vertical or horizontal fre separation applications.

8 The fre rated systems published are suitable for load bearing walls within the scope of the NZS 3604. Beyond the scope of the NZS 3604, a specifc engineering Design (SED) must be followed. Ask James Hardie on 0800 808 868 for further assistance. Compliance NZBC CLAUSE C PROTECTION FROM FIRE The fre resistance rating (FRR) of James Hardie fre rated systems have been verifed through full scale testing and technical assessments. The systems published in this Design Manual are suitable to achieve passive fre protection requirements of the NZBC Clause C/AS1 - C/AS2 Protection From Fire.

9 NZBC CLAUSE B2 DURABILITY James Hardie products meet the serviceable life of 50 years and satisfy the performance requirements of the NZBC Clause B2 Durability . It must be ensured the James Hardie products are installed and maintained in accordance to their published technical specifcations. NZBC CLAUSE G6 AIRBORNE & IMPACT SOUND The STC and IIC ratings for the systems published in this Design Manual have either been established through testing or Acoustic modelling. Designers/specifers must ensure that the ratings published in this Manual are suitable for the intended applications.

10 In case higher ratings are required, ask James Hardie on 0800 808 868 for assistance. SOUND For compliance with clause G6 of the NZBC (STC > 55) James Hardie fre and Acoustic systems have either been tested at the Acoustic Testing Service, University of Auckland, or have been conservatively derived by technical opinions from Acoustic consultant Marshall Day Acoustics. Data values published here have an expected accuracy of 3 STC points. 6 Fire & Acoustic Design Manual | November 2020 New Zealand Responsibility SPECIFIER If you are a designer/specifer ensure that you are familiar with the approved document for Fire Safety, Clause C of the NZBC and check its requirements.
