Overview

The water purification material testing institution is a third-party professional organization specialized in conducting hygiene, safety, and performance testing on purification materials that come into contact with drinking water. Its core responsibility is to ensure public water safety through scientific testing.

Product Details

1、 Detection object and scope

Water treatment materials

Adsorption type: Activated carbon, molecular sieve, ion exchange resin, etc., detect their adsorption efficiency (such as residual chlorine, heavy metal removal rate), and safety of dissolved substances (such as organic pollutants, heavy metal precipitation).

Filtration type: ultrafiltration membrane, reverse osmosis membrane, filter element (PP cotton, ceramic filter element, etc.), testing filtration accuracy (molecular weight cut-off, desalination rate), service life (pollutant capacity, pressure resistance).

Chemical treatment agents: disinfectants (sodium hypochlorite, ozone), coagulants (polyaluminum chloride, aluminum sulfate), tested for active ingredient content, toxicological safety (such as disinfection byproduct generation risk), and treatment effectiveness (such as sterilization rate, turbidity removal rate).

Water transmission and distribution equipment and protective materials

Pipe fittings: PPR pipes, PE pipes, stainless steel water tanks, tested for immersion water hygiene indicators (heavy metal and volatile organic compound leaching), material corrosion resistance, and sealing performance.

Protective coatings: epoxy resin coatings, polyester coatings, tested for their safety after contact with water (such as formaldehyde and benzene emissions).

2、 Core testing items

Health and safety testing

Toxicological indicators: content of heavy metals such as lead, mercury, cadmium, arsenic, and volatile organic compounds such as formaldehyde and benzene, ensuring that the dissolved substances of the materials comply with the "Sanitary Standards for Drinking Water" (GB 5749).

Microbial indicators: total number of bacteria, total coliform group, to prevent material from breeding bacteria and contaminating water quality.

Sensory characteristics: color, turbidity, odor, and taste, ensuring normal appearance and odor of the water body.

Performance effectiveness testing

Adsorption/filtration performance: such as the adsorption rate of activated carbon for residual chlorine and the desalination rate of reverse osmosis membrane.

Durability: the dirt capacity of the filter element, and the aging resistance of the pipe.

Structural safety: sealing of water tank, pressure resistance of pipes.

Special indicator testing

Migration test: Whether the migration of specific substances such as plasticizers and bisphenol A meets the limit values.

Radioactive index: detecting the risk of radioactive contamination of materials.

3、 Service process and report value

Testing Process

Customers submit samples and testing requirements → Institutions determine testing items and methods → Standardized sampling (to ensure representativeness) → Advanced instrument testing → Strict quality control (such as data review, blind sample testing) → Report issuance.

Report function

Enterprise end: Verify product compliance, optimize production processes, and enhance market competitiveness.

Regulatory end: Provide technical basis for the approval of "hygiene and safety permits for water related products" by the health department.

Consumer end: Ensure public water safety and avoid water pollution risks caused by substandard materials.

4、 Industry qualifications and standards

Qualification requirements: Must possess CMA (China Metrology Accreditation) or CNAS (China National Accreditation Service for Conformity Assessment) qualifications to ensure the legal validity and international mutual recognition of test results.

According to the standard:

Sanitary Standards for Drinking Water (GB 5749)

Specification for Hygiene and Safety Evaluation of Drinking Water Transmission and Distribution Equipment and Protective Materials (GB/T 17219)

Regulations on Inspection of Drinking Water Hygiene and Safety Products (Wei Fa Jian Fa [2001] No. 254)

Industry or local standards (such as specialized specifications for specific materials).

5、 Typical application scenarios

New product development: When enterprises develop new filter elements or membrane materials, their safety and performance need to be verified through testing.

Market access: Domestic water related products need to submit testing reports to provincial health departments and apply for health permit approvals.

Quality inspection: Regulatory authorities conduct random inspections on water related products circulating in the market to crack down on unqualified products.

Engineering acceptance: Water purification projects (such as direct drinking water systems in schools and hospitals) need to pass testing to ensure that water quality meets standards.

Summary: Water purification material testing institutions provide quality control for the entire chain of water related products from research and development to market through scientific testing and strict standards, and are the "gatekeepers" to ensure public water safety. Its testing report is not only a "pass" for product compliance, but also an important reference for consumers to choose safe products.
