Test conclusion: Pass
According to the report, the sample and related information were provided by the client. The reported conclusion applies to the specific sample tested under the conditions described in the report.
RoHS stands for Restriction of Hazardous Substances. The European Union's RoHS framework restricts certain hazardous substances in electrical and electronic equipment within its scope.
The SGS report evaluated the specified PP film sample against the substance restrictions listed under EU RoHS Directive (EU) 2015/863. The assessment covered ten restricted substances or substance groups, including heavy metals, brominated flame retardants, and certain phthalates.
The tested substances included:
Lead (Pb)
Mercury (Hg)
Cadmium (Cd)
Hexavalent chromium (Cr(VI))
Polybrominated biphenyls (PBB)
Polybrominated diphenyl ethers (PBDE)
Bis(2-ethylhexyl) phthalate (DEHP)
Butyl benzyl phthalate (BBP)
Dibutyl phthalate (DBP)
Diisobutyl phthalate (DIBP)
The report records a Pass conclusion for the requested testing. In the detailed results, the listed substances and relevant substance groups were reported as ND, meaning not detected above the applicable method detection limits.
This result provides customers with specific, report-based information about the tested sample. It is important to distinguish a successful test against specified RoHS requirements from a general product certification or a declaration that every product manufactured by a company meets the same requirements.
Cooling tower fill is a key component in evaporative cooling systems. It increases the contact area between water and air, helping promote heat and mass transfer so that heat can be released from circulating water.
Because cooling tower fill operates in environments involving continuous water circulation, airflow, and temperature changes, selecting appropriate materials is important. Buyers need to consider material characteristics, product design, operating conditions, and available technical documentation.
A third-party laboratory report provides documented evidence of the results obtained from a specific sample under defined testing conditions.
For purchasing teams, this information can support supplier assessments, technical reviews, and internal quality documentation.
International buyers often need clear information about the materials used in industrial products. A detailed test report identifies the sample, testing requirements, methods, and results, helping buyers understand exactly what was evaluated.
At Power Tower Cooling Technology (Shaoxing) Co., Ltd., we recognize the importance of making relevant product information available to customers evaluating cooling tower components.
When comparing cooling tower fill suppliers, buyers may review material test reports alongside product specifications, manufacturing information, quality-control procedures, and other relevant technical documents.
The SGS report for our PP film sample adds an independent test record to the documentation available for evaluating this material.
A purchasing decision should consider more than the initial product price. Buyers should also evaluate the intended application, fill configuration, water quality, maintenance requirements, and the suitability of the material for the operating environment.
Appropriate technical documentation helps customers make decisions based on project requirements rather than assumptions.
Polypropylene (PP) is used in a wide range of industrial applications because of its useful material properties. PP film can be formed into cooling tower fill structures designed to increase the contact area between water and air.
However, the performance of a specific PP cooling tower fill product depends on more than the base material alone. Product geometry, sheet thickness, manufacturing quality, installation, water quality, and operating conditions can all affect suitability and performance.
When selecting PP cooling tower fill, buyers should consider the following factors.
Cooling tower fill designs vary according to the tower's airflow and water distribution arrangement. Crossflow and counterflow cooling towers may require different fill configurations and dimensions.
The selected fill should match the cooling tower's original design or the requirements of the replacement project.
Water temperature, circulating water flow, suspended solids, mineral content, and biological growth can affect fill selection and maintenance requirements.
For systems with a higher risk of fouling, buyers should evaluate the fill design and its suitability for the actual water conditions.
Correct dimensions and configuration are important for installation and water distribution. Before ordering replacement fill, buyers should verify the required dimensions, layout, and compatibility with the existing cooling tower.
Available technical documents may include material specifications, product drawings, test reports, and relevant quality records.
The SGS report discussed in this article concerns the specified RoHS-related substances in the tested PP film sample. It does not independently establish thermal performance, cooling efficiency, mechanical strength, service life, or suitability for every industrial application. These characteristics should be evaluated separately using relevant technical data and testing where necessary.
At Power Tower Cooling Technology (Shaoxing) Co., Ltd., we understand that customers need reliable information when sourcing cooling tower fill and related components.
We believe that clear product information and relevant technical documentation help build confidence between manufacturers and customers. Independent testing is one way to provide additional information about material characteristics and specified compliance requirements.
The SGS test report dated October 23, 2026, records a Pass conclusion for the requested EU RoHS-related testing of our PP film sample. We are pleased to share this result as part of our commitment to transparent product evaluation and customer support.
At the same time, we recognize that different projects and markets may have different documentation requirements. Customers should confirm whether a particular test report applies to the exact product and material they intend to purchase.
Our team can help customers review product details and identify the relevant technical information for their cooling tower applications.
Choosing a supplier involves evaluating product suitability, documentation, manufacturing capabilities, and technical support.
Here are several practical points buyers should consider.
Confirm the material, dimensions, fill configuration, and intended application before placing an order. For replacement projects, check compatibility with the existing cooling tower.
Ask suppliers for available material test reports and verify the sample descriptions, report dates, testing scope, and conclusions. Ensure that the documents correspond to the product being evaluated.
Consider the operating water temperature, water quality, cooling requirements, and maintenance conditions. A material or fill design suitable for one system may not be the best choice for another.
A supplier should be able to clarify product information and help customers identify the details required for project evaluation.
By considering these factors together, buyers can make more informed decisions when sourcing cooling tower fill for industrial and HVAC applications.
