- The result is in the report.
Some data sheet figures are FORSPEC R&D results or manufacturer classifications. The data sheet says so beside each one, and they are not listed here.
Who tests it.
The membrane, sheet and tile adhesive reports are issued by XTec Gen Laboratories. Each report states on its first page that the lab is accredited for compliance with ISO/IEC 17025 (testing), accreditation number 20678.
Each report covers one product, or one product pair tested together. It carries its own number, issue date and results. The report is the record: this page only points to it.
What each test means.
AS/NZS 4858Wet area membranes
Bathrooms, showers, laundries
Grades a membrane by how far it stretches before it breaks. The class then sets how wide the unbonded strip (bond breaker) must be at joints that move.
| Class I | stretches 10 to 59% | 100 mm bond breaker |
|---|---|---|
| Class II | 60 to 299% | 35 mm |
| Class III | 300% or more | 12 mm |
A higher class is not a better grade. It tells the installer how to detail the joints.
AS 4654.1External above-ground membranes
Roofs, decks, balconies, planters
Sets the lab tests for a membrane used outside. Which tests apply depends on how it is fixed, whether it is left exposed, and the traffic it takes. It uses the same three stretch classes.
| Water and detergent | keeps 25% or more of its stretch | |
|---|---|---|
| Heat ageing | keeps 50% or more | |
| UV, 1,000 hours | keeps 40% or more | exposed membranes |
A moving-joint test then confirms the class.
AS ISO 13007Tile adhesives, and membranes under tile
Tiled floors and walls
Part 1 gives a tile adhesive a short code. Part 5 tests a liquid membrane together with the adhesive and tile fixed over it.
| C2 | cement adhesive, improved bond | 1.0 N/mm² or more |
|---|---|---|
| S1 | deformable | bends 2.5 mm to under 5 mm |
| Part 5 | five tile pull-off tests | 0.5 N/mm² or more each |
Part 5 also needs no water through the membrane and a 0.75 mm crack bridged.
Low VOC certificates.
Certificates on file, one per product.
Questions
Who tests FORSPEC products?
The membrane, sheet and tile adhesive reports on this page are issued by XTec Gen Laboratories. Each report states that the lab is accredited for compliance with ISO/IEC 17025 for testing.
Is a Class III membrane better than Class II?
Not by itself. The class says how far the membrane stretches before it breaks. It sets the bond breaker width at joints: 12 mm for Class III, 35 mm for Class II.
Where can I download the test reports?
Every report listed here opens as a PDF. The full set, with each data sheet and safety data sheet, is on the Technical Data page.
Does a test report cover the whole system?
A report covers the product, or the product pair, named on it. Ask FORSPEC for the system specification for your job.
