1、Use or observance of AHAM standards is voluntary.AHAM standards are presented to the American National Standards Institute （ANSI） for recognition as American National Standards. This standard was so recognized on April 9, 2002 and bears the American National Standard designation ANSI/AHAM AC-1-2002.

2、This standard contains test procedures which may be applied to any brand or model of portable household electric cord-connected room air cleaners within the stated confines of the standards limits of measurability for measuring performance. Results of tests in accordance with this standard may be pu

3、blicly stated.With regard to safety, AHAM recommends that all appliance products - both major and portable - manufactured or marketed in the United States be submitted to an appropriate independent laboratory for inspection and listing in conformance with the safety standards and procedures followed

4、 by such laboratories. The relevant standards for portable household electric cord connected room air cleaners are UL 867, Standard for Electrostatic Air Cleaners and UL 507, Standard for Fans.The appendices to this standard are generally for informational purposes except where referenced in the bod

5、y of the standard.AHAM welcomes comments and suggestions regarding this standard. Any standard may be reviewed and improved as needed. All standards must be updated or reconfirmed at least every five years. Any interested party, at any time, may request a change in an AHAM standard. Such request sho

6、uld be addressed to AHAMs President, and should be accompanied by a statement of reason for the request and a suggested alternate proposal.This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems associated with it

PURPOSEThis standard method establishes uniform, repeatable procedures and standard methods for measuring specified product characteristics of portable household electric cord-connected room

14、 air cleaners.The standard methods provide a means to compare and evaluate different brands of portable household electric cord connected room air cleaners regarding characteristics significant to product use.The standard methods of measurement are not intended to inhibit improvement and innovation

15、in product testing, design or performance.2. SCOPEThis standard method applies to portable household electric cord-connected room air cleaners as defined in Section 3.This standard method includes definitions and safety characteristics of portable household electric cord-connected room air cleaners

16、of the types indicated.This standard method measures the relative reduction by the air cleaner of particulate matter suspended in the air in a specified test chamber.This standard method has defined limits of measurability. The statistical validity of test results outside of the stated practical lim

17、its is questionable and unevaluated. The practical limits of measurability are:Dust 10 to 400 CADRTobacco smoke 10 to 400 CADRPollen 25 to 450 CADRThe precision of the Standard as based on a 0 CADR air cleaner expressed as 2 standard deviation limits （95%） are:Dust + 10 CADR Tobacco smoke + 10 CADRP
