AMPAC USA Certifications and Quality Standards

AMPAC USA designs and manufactures water purification systems that meet the most demanding third-party certification requirements in the industry. Our certifications aren't marketing badges — each one specifies what the certified system must achieve in performance testing, material safety, and quality management. Here's what each certification means for buyers specifying a water treatment system.

NSF/ANSI 58: Reverse Osmosis Systems

NSF International Standard 58 is the primary performance and safety certification for reverse osmosis drinking water systems sold in the United States. Third-party certification to NSF/ANSI 58 requires independent laboratory testing and ongoing production audits — no manufacturer can self-certify.

What NSF/ANSI 58 Verifies

• Contaminant reduction claims: The certified system must demonstrably reduce each contaminant listed on its performance data sheet by the claimed percentage. Test protocols use standardized challenge water with specific concentrations of each contaminant.
• Structural integrity: Pressure vessels and membranes must withstand 1.5x rated operating pressure without failure or leakage.
• Material safety: All wetted materials (housing, tubing, membrane, O-rings) are evaluated for extraction of potentially harmful substances into the treated water. Materials must not leach lead, phthalates, or other regulated substances above allowable limits.
• Product literature accuracy: Performance claims in marketing materials and specification sheets must be consistent with test results.

AMPAC USA commercial RO systems from 200 GPD through 8,000 GPD are tested and certified to NSF/ANSI 58. The certification applies to both the membrane elements and the complete assembled system.

NSF/ANSI 61: Drinking Water System Components

NSF/ANSI 61 covers a broader category of drinking water contact materials — valves, fittings, pipes, coatings, and system components that come into contact with potable water but aren't covered by product-specific standards like NSF 58. The standard evaluates each material for extraction of contaminants including heavy metals, regulated organics, and volatile organic compounds.

For commercial installations where local health departments require documentation that all water-contact materials are evaluated for potable water safety, NSF/ANSI 61 compliance documentation for AMPAC system components is available on request.

ISO 9001:2015 — Quality Management System

ISO 9001 is the international standard for quality management systems. AMPAC USA manufacturing and engineering operations are conducted under ISO 9001:2015 quality management system requirements. ISO certification is audited by an accredited third party on an annual basis.

What ISO 9001:2015 Means for AMPAC Products

QMS Requirement	What It Means for Your System
Design control	System designs follow documented engineering review and approval processes. Changes to designs are controlled and traced.
Incoming material inspection	RO membranes, pressure vessels, pumps, and control components are inspected against specification before assembly. Suppliers are qualified and monitored.
In-process quality checks	Assembly steps are performed to documented work instructions. Critical parameters (pressure, flow, TDS rejection) are checked at defined stages.
Factory performance testing	Every system is wet-tested before shipment. Test records including permeate flow rate, TDS rejection, and operating pressure are retained for each unit.
Traceability	Membrane lot numbers, pressure vessel serial numbers, and component batch records are traceable to each finished system shipped.
Corrective action	Field performance issues are documented and fed back into the design and manufacturing process. Recurring issues trigger root cause investigation and corrective action.

ISO 9001 certification is particularly relevant for procurement teams in regulated industries (pharmaceutical, food processing, government) that require documented quality management from their suppliers as a condition of vendor approval.

WQA: Water Quality Association

AMPAC USA is a member of the Water Quality Association (WQA), the principal trade association for the water treatment industry in North America. WQA membership represents participation in industry standards development, access to technical education programs, and adherence to the WQA code of ethics for water treatment businesses.

Specifications for Regulated Industry Procurement

If you are procuring a water treatment system for a pharmaceutical, food and beverage, or government application that requires specific certification documentation as part of a vendor qualification process, AMPAC USA can provide:

• NSF/ANSI 58 certification documentation for the specific model
• ISO 9001 certificate of registration with scope description
• Material safety data (materials of construction, wetted material list)
• Factory test records for a shipped unit (on request)
• Letter of conformance to applicable standards on company letterhead
