ABSTRACT
This specification covers detergent feeders, rinse additive feeders, and sanitizing agent feeders intended to automatically maintain the concentration of additives in the wash, recirculated rinse, or non-recirculated rinse water of commercial spray- type dish-washing and glass-washing machines. Detergent, rinse additive, and sanitizing agent feeders shall be of the following types and styles: Types I, II, III, IV, V, and VI; and Style I; II; III; IV; V; and VI. Materials used shall be free from defects that would adversely affect the performance or maintainability of individual components or of the overall assembly. The feeder shall be complete so that when connected to the specified source of power (electrical or water, or both), the unit can be used for its intended function. Feeders shall be tested in accordance with specified requirements.

Overview

ASTM F1021-18 is the Standard Specification for Feeders, Detergent, Rinse Agent, and Sanitizing Agent for Commercial Dishwashing and Glasswashing Machines. Issued by ASTM International, this specification defines the requirements for automatic feeders designed to maintain the correct concentration of additives-such as detergents, rinse aids, and sanitizers-in the wash and rinse water of commercial spray-type dishwashing and glasswashing equipment. The standard ensures that feeders are designed and manufactured to optimize performance, reliability, and safety, enhancing washing effectiveness and compliance with health standards in commercial kitchens.

Key Topics

• Types and Styles of Feeders: The standard categorizes feeders based on their function and type of additive dispensed, including detergent feeders, rinse additive feeders, and sanitizing agent feeders. Each type may offer different methods of additive delivery, such as timed or concentration-controlled mechanisms, and accommodate various physical forms like liquid, powder, or solid cast products.
• Material and Manufacturing Requirements: Feeders must be constructed from corrosion-resistant and durable materials, such as 300 series stainless steel and certified plastics, ensuring longevity and consistent operation in harsh commercial environments.
• Operation and Safety: Feeders must be complete, ready to use upon connection to the specified power source, and designed to minimize splash and spillage. Electrical and plumbing connections must comply with relevant codes and standards to support safe and reliable operation.
• Testing and Certification: The specification outlines performance and quality assurance testing requirements, referencing industry standards such as NSF 29 and UL 73. Certification from recognized bodies may be required to verify compliance.
• Marking and Documentation: Products covered by ASTM F1021-18 must be permanently marked for identification and supplied with comprehensive manuals detailing installation, operation, maintenance, and servicing as per food service equipment regulations.

Applications

ASTM F1021-18 is applicable to a variety of commercial food service and hospitality environments, including:

• Restaurants and Cafeterias: Streamlining the cleaning process by automatically dispensing precise amounts of detergents, rinse agents, and sanitizing chemicals into dishwashers and glasswashers.
• Hotels and Catering Facilities: Supporting large-scale washing operations that demand consistent chemical dosing for hygiene and efficiency.
• Healthcare and Institutional Kitchens: Ensuring regulatory compliance and the highest standards of cleanliness in environments where food safety is critical.
• Commercial Kitchens with Spray-Type Machines: Designed specifically for compatibility with commercial spray-type dishwashing and glasswashing machines, where automatic additive dosing improves washing results and operational safety.

By adhering to ASTM F1021-18, organizations can achieve improved cleaning results, prolong the life of their washing equipment, maintain health code compliance, and enhance workplace safety with reduced manual chemical handling.

Related Standards

ASTM F1021-18 references several important standards relevant for chemical feeders and their integration in commercial dishwashing systems:

• NSF 29 – Detergent/Chemical Feeders for Commercial Dishwashing Machines
• NSF 51 – Plastic Material and Components Used in Food Equipment
• UL 73 – Motor Operated Appliances
• UL 94 / UL 746C – Flammability and use of plastic materials in electrical equipment
• ASSE 1001 – Atmospheric Type Vacuum Breakers
• BOCA Basic Plumbing Code – Plumbing connection standards for feeders
• ASTM D3951 – Commercial Packaging
• ASTM F760 – Food Service Equipment Manuals

These related standards provide additional requirements on safety, material quality, testing, documentation, and installation, ensuring that equipment covered by ASTM F1021-18 meets the needs of modern commercial kitchens and institutional environments seeking reliable, automatic chemical dosing solutions.
