The purpose of this standard is to establish for Self-Contained, Mechanically-Refrigerated Drinking- Water Coolers: definitions; test requirements; rating requirements; minimum data requirements for Published Ratings; operating requirements; marking and nameplate data; and conformance conditions.

AHRI 275-2018

Application of Outdoor Unitary Equipment A-weighted Sound Power Ratings

The purpose of this standard is to establish for outdoor unitary equipment: definitions, procedures for estimating A-weighted Sound Pressure Levels from the A-weighted Sound Power Ratings, and recommended application practices. This standard applies to the outdoor sections of factory-made air-conditioning and heat pump equipment as defined in the following AHRI standards, when rated in accordance with AHRI Standard 270. 1. AHRI Standard 210/240, Unitary Air-conditioning and Air-source Heat Pump Equipment; 2. AHRI Standard 340/360, Commercial and Industrial Unitary Air-conditioning and Heat Pump Equipment (cooling capacity ratings of equal to or less than 40.0 kW); 3. AHRI Standard 1230, Variable Refrigerant Flow (VRF) Multi-split Air-conditioning and Heat Pump Equipment (cooling capacity ratings of equal to or less than 40.0 kW); 4. ANSI/AHRI Standards 1160 (I-P) and 1161 (SI), Heat Pump Pool Heaters.

ANSI/AHRI 710-I-P-2009

Performance Rating of Liquid-Line Driers

This standard establishes a single set of requirements for the testing and rating of water capacity and refrigerant flow capacity for driers to be used in the liquid lines of refrigerating and air-conditioning systems; whereby, equipment performance can be compared from product to product.

ANSI/ADA 27-2016

Polymer-based Restorative Materials

This Standard specifies requirements for dental polymer-based restorative materials supplied in a form suitable for mechanical mixing, hand-mixing, or intra-oral and extra-oral external energy activation, and intended for use primarily for the direct or indirect restoration of cavities in the teeth and for luting. The polymer-based luting materials covered by this Standard are intended for use in the cementation or fixation of restorations and appliances such as inlays, onlays, veneers, crowns and fixed partial prostheses. This Standard does not cover those polymer-based luting materials that have an adhesive component within the structure of the material. This Standard does not cover materials intended to prevent caries (see ISO 6874) or those used for veneering metal sub-frames (see ISO 10477).
