The 16th Edition IEE Wiring Regulations, adopted as British Standard BS7671 in 1992, has been revised and a new version released. The complete amended Regulations will now carry a blue cover to distinguish them from the previous yellow-covered version (ISBN 0 85296 927 9). The Regulations are the national standard to which all domestic and industrial wiring must conform. Amendments incorporated in the new BS7671:2001 affect several sections and include substantial changes to align with European documents. There are also two wholly new sections. Unsold copies of the previous version can be withdrawn from sale and returned to the IEE for refund, provided that copies of the new version are ordered.
