Test methods and standards
ASTM F150 - 06
Standard Test Method for Electrical Resistance of Conductive and Static Dissipative Resilient Flooring
Significance and Use
Conductive and static dissipative floors (static control flooring) serve as a convenient means of electrically connecting persons and objects together to prevent the accumulation of electrostatic charges. A static control floor is specified on the basis of controlled resistance values. The surface of the floor provides a path of moderate electrical conductivity between all persons and equipment making contact with the floor to prevent the accumulation of dangerous electrostatic charges. Static control footwear will need to be used in conjunction with the floor for the floor to perform effectively with personnel.
The resistance of some flooring materials change with age. Floors of such materials should have an initial resistance low enough or high enough to permit increase or decrease in resistance with age without exceeding the limits prescribed in the product specifications.
1.1 This test method covers the determination of electrical conductance or resistance of resilient flooring either in tile or sheet form, for applications such as hospitals, computer rooms, clean rooms, access flooring, munition plants, or any other environment concerning personnel-generated static electricity.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Who Uses Standards and Why?
Who uses ESD standards?
The list is quite broad, and includes manufacturers, purchasers, and users of ESD sensitive devices and products, manufacturers and distributors of ESD control products, certification registrars, and third party testers of ESD control products.
Why use ESD standards?
The reasons are numerous:
- They help assure consistency of the reported susceptibility of ESD sensitive products.
- They help assure consistency of ESD control products and services.
- They provide a means of objective evaluation and comparison among competitive ESD control products.
- They help reduce conflicts between users and suppliers of ESD control products.
- They help in developing, implementing, auditing, and certifying ESD control programs.
- They help reduce confusion in the marketplace.
In the United States, the use of ESD standards continues to be voluntary. However, their use can be written into contracts or purchasing agreements between buyer and seller. In much of the rest of the world, the use of standards, where they exist, is compulsory.
