Why Testing Before Installation Saves Thousands
Verify Slip Resistance Before Installation
Slip resistance certification before installation reduces financial and compliance risk. Small formulation or finish changes can materially alter performance classification. Laboratory testing to AS 4586:2013 confirms P or D ratings before product rollout, preventing costly remediation and rejected certifications.
Certification Is Risk Insurance
Slip testing is often viewed as a procedural requirement. In reality, it is a financial safeguard.
A surface installed across multiple sites that later fails to meet classification can trigger:
- Removal and replacement costs
- Project delays
- Contract disputes
- Insurance complications
- Reputational damage
Testing before installation prevents downstream correction.
Small Changes, Different Results
Slip resistance performance can vary due to:
- Surface finish variation
- Colour pigment differences
- Glaze adjustments
- Anti-slip additive concentration
- Coating selection
- Sealant application
Two visually similar tiles may produce materially different wet pendulum values.
Laboratory testing isolates and measures performance under controlled conditions.
Understanding AS 4586:2013
AS 4586:2013 classifies new surfaces under laboratory conditions.
Common methods include:
- Wet Pendulum (P0–P5 classification)
- Dry Floor Friction (D0/D1 classification)
The selected method depends on intended installation conditions.
Testing provides objective classification suitable for:
- Architects
- Builders
- Certifiers
- Consultants
- Project documentation
- Flooring providers
- Floor coating specialists
Avoiding Rejected Reports
Incomplete or non-standard reports can be rejected by certifiers.
A compliant laboratory report should include:
- Method reference
- Equipment calibration
- Test conditions
- Classification result
- Photographic identification
- Traceable documentation
- A NATA-accredited testing company
Testing through an accredited laboratory reduces approval friction.
Logistics Should Not Delay Testing
Project timelines are tight. Logistics can complicate sample delivery.
Zerofal offers national courier coordination to simplify sample collection and delivery.
Testing early in the specification or supply phase prevents installation risk.
Zerofal Laboratory Testing
Zerofal provides:
- Slip resistance testing to AS 4586:2013
- Wet pendulum and dry friction methods
- Clear classification reporting
- National sample coordination
- Fast turnaround suitable for project schedules
Reports are structured for compliance and submission.
Confirm Slip Resistance Before You Install
Slip resistance classification should be verified before products are specified or installed.
Laboratory testing to AS 4586:2013 confirms P or D ratings under controlled conditions, ensuring the selected surface meets performance requirements before rollout. This reduces the risk of failed compliance, rejected certifications, and costly remediation after installation.
Testing prior to installation provides clarity at the point where changes are still practical and cost-effective.
