Standards in Development

Print | Share This
New NEIS are developed through a thoughtful, collaborative process. NECA carefully analyzes industry needs and feedback through the NEIS ”Industry Review“ process.

During the Industry Review stage, industry professionals review proposed standards to confirm that NECA’s intentions and initiatives are correct and timely. Existing NEIS must also be revised or reaffirmed on a five-year cycle to remain compliant with the requirements of the American National Standards Institute (ANSI).ansi

NECA 504 (200x) - Standard for Installing Light Control Devices and Systems

This standard describes the installation and related work for lighting controls commonly used in commercial, institutional, industrial and residential buildings.

NECA 414 (201x), Standard for Installing and Maintaining Wind Power Generation Systems

This standard describes the application procedures for installing wind power generation turbines.

NECA 781 (201x), Recommended Practices for Lightning Protection System Design and Installation

The purpose of developing this standard is to is provide a “Best Practices” lightning protection system installation and maintenance standard that ensures the completed installation meets or exceeds expected quality and performance criteria and complies with the minimum requirements of NFPA® 780, Standard for the Installation of Lightning Protection Systems. This standard will cover procedures regarding the following: 1. Pre-Construction Site Assessment to ensure proper design and selection of proper materials 2. Project Management procedures to obtain approvals from owner, architect, engineers and other trades for correctness and completeness of the shop drawing design and mounting details.
