Direct Answer
A 3,000-hour accelerated UV duration is a project target when specified; it is not proof that a PE rattan product passed laboratory testing. Verify the method and cycle, tested sample and product scope, measured result, and acceptance criteria. No Greenlife-specific product UV report is currently published on this website.
Project Target vs. Published Test Evidence
A requested exposure duration is a project requirement. A verified result also needs a traceable method, tested specimen, measured result, and acceptance rule.
| Field | Current information | Evidence status |
|---|---|---|
| Project target | A 3,000-hour accelerated UV duration may be specified for a project; the method and exposure cycle still need confirmation. | Planning target only; not a test result. |
| Test method | No Greenlife-specific standard, edition, apparatus, or exposure cycle is published here. | Not publicly verified. |
| Tested sample | No sample code, formulation, profile, color, or batch is linked to a published Greenlife UV report. | Not publicly verified. |
| Measured result | No Greenlife-specific UV test result or redacted report summary is published here. | No product pass result claimed. |
| Acceptance criteria | No product-specific acceptance criteria are published with a Greenlife UV result. | Not publicly verified. |
| Evidence status | A report scope connecting the result to the offered product is not currently available on this site. | A 3,000-hour target must not be presented as a verified product result. |
What Accelerated Weathering Can Show
Accelerated weathering exposes a defined sample to controlled light, moisture, and temperature conditions so materials can be compared under the stated method. The result belongs to that apparatus, cycle, specimen, evaluation, and acceptance rule.
Do not convert 3,000 laboratory hours into a fixed number of outdoor years. Real exposure varies by latitude, season, orientation, shade, heat, moisture, pollutants, cleaning, furniture design, and use.
What the Test Cannot Show
A laboratory exposure result cannot establish a universal outdoor lifetime, warranty period, or performance for every climate, furniture design, color, profile, formulation, or maintenance routine.
ASTM G154 and ISO 4892-3 cover fluorescent UV approaches, while ASTM G155 and ISO 4892-2 cover xenon-arc approaches. Results from different apparatus, cycles, lamps, filters, or evaluation rules are not automatically comparable.
Report Fields Buyers Should Verify
Request the laboratory and report date, test standard and procedure, apparatus, lamp or light source, exposure cycle, total hours, specimen code, polymer formulation reference, profile, dimensions, surface, color, batch, conditioning, control sample, measured properties, visual evaluation, acceptance criteria, result, photographs, deviations, and limitations.
A marketing statement that omits sample identity or the operating cycle cannot show that the offered bulk material matches the tested specimen.
Color, Profile, and Formulation Differences
Confirm that the report covers the formulation, color, profile, surface, and production version offered for the order. A result for one pigment, stabilizer package, profile thickness, or production sample does not automatically apply to every catalog item.
Keep the report reference with the approved physical sample, item code, color, profile, order revision, batch record, and buyer acceptance rule.
UV Grade Should Match Exposure
UV grade should match exposure. Define the intended climate, placement, orientation, shade, heat, moisture, cleaning routine, furniture design, and warranty position before selecting an evidence requirement.
Real outdoor conditions still matter: latitude, season, pollutants, abrasion, trapped heat, standing water, and maintenance can change how a finished furniture program performs.
The buyer remains responsible for deciding whether the evidence and sample are suitable for the destination market and finished furniture program.
Current Evidence Status
The following Greenlife-specific records are not currently published: an actual UV report or redacted summary, permission to publish the laboratory name and report number, tested sample code, profile and color, exposure cycle, acceptance criteria, before-and-after photographs, and a signed statement defining scope and limitations.
Until those records are supplied, this page explains how to evaluate a report and does not claim that a specific Greenlife product passed a 3,000-hour test.

Buyer Decision Points
Approve the material only after the guide's relevant checks are tied to the actual product, frame, market, and repeat-order record.

- What the Test Cannot Show
- Report Fields Buyers Should Verify
- Color, Profile, and Formulation Differences
Factory Process or Test Method
Start with the buyer's application and reference sample, document the relevant profile, color, performance, and packing requirements, then compare the production sample on the intended frame before bulk approval.
Common Mistakes
Common errors are approving from a screen photo alone, omitting the actual frame or exposure condition, treating a color name as a repeatable standard, and leaving packing or batch identification until after production.

Buyer FAQ
These answers explain how to apply the guide without treating it as a substitute for buyer-specific testing.
Does a 3,000-hour UV test equal five years outdoors?
No. Accelerated exposure hours do not convert to a fixed outdoor service period. The method, cycle, sample, climate, application, and acceptance criteria all matter.
What should a PE rattan UV report identify?
It should identify the laboratory, date, standard and cycle, apparatus, sample code, formulation reference, color, profile, batch, evaluated properties, acceptance criteria, results, deviations, and limitations.
Can ASTM G154 and ASTM G155 results be compared directly?
Not automatically. They use different light-source approaches, and results depend on the selected apparatus, cycle, filters or lamps, temperature, moisture, specimens, and evaluation.
Does one tested color cover every PE rattan color?
No. Pigments and additives can affect weathering behavior. Match the evidence to the offered formulation, color, profile, and production version.
What should buyers approve before bulk production?
Approve the report scope, physical sample, profile, color, actual-frame test, acceptance rule, item code, and record linking the tested evidence to the bulk material.
Limitations
This guide supports purchasing and sample review, but it does not replace testing on the buyer's actual frame, exposure conditions, production equipment, or acceptance standard. UV test hours are laboratory test conditions and are not a fixed conversion to outdoor service years.
