11.2.1 Compliance
Closed panel systems shall comply with the Technical Requirements.
Closed panel systems that comply with the guidance in this chapter and associated chapters will generally be acceptable. This chapter should be used in conjunction with guidance in Chapter 11.1 MMC Systems: general requirements.
As many components of closed panel systems cannot be inspected on site, they should be treated as a building system as defined in Chapter 2.1, Standards and Technical Requirements and subject to assessment by an independent technical approvals authority or assessed under the NHBC Accepts service; www.nhbc.co.uk/accepts.
