Why Choose BRS-PET-FR-HL3 Split Braided Sleeving?
• Address Railway Fire Requirements
The referenced construction meets EN 45545-2 R22 and R23 at HL3 for projects that specify railway fire-performance documentation.
• Reduce Approval Uncertainty
The product is positioned by requirement set, hazard level and tested construction instead of relying on a generic flame-retardant claim.
• Simplify Vehicle Retrofit Work
The self-closing sleeve installs around terminated railway harnesses during refurbishment, repair and equipment upgrades.
• Support Engineering Documentation Review
Available test information can be matched to the proposed size, installation location and customer project specification before approval.
1. EN 45545-2 HL3 Performance
The referenced construction meets the R22 and R23 requirement sets at HL3.
2. Maintenance-Friendly Installation
The self-closing split design supports installation, inspection and servicing of railway harnesses.
3. Adaptable Vehicle Routing
The flexible braid follows rail-vehicle cable paths and accommodates branch-outs.
4. Lightweight Harness Protection
The sleeve provides mechanical protection without enclosing the bundle in a rigid conduit.
5. Overlapping Bundle Coverage
The wrap-around construction helps maintain cable containment along changing vehicle routes.
6. Accessible Retrofit Design
The sleeve installs around terminated assemblies during rail-vehicle upgrades and repair work.
7. Project Documentation Review
Test documentation can be matched to the proposed size and railway requirement.

● Note: Select the size by installed bundle diameter and verify at least 35% overlap at the largest section. Final part-number format, reel length and approved report scope should be confirmed before publication and production release.
Typical Applications
Passenger Information Systems
Protects communication and display wiring routed through passenger areas and equipment modules.
Railway Control Cabinets
Organizes control, signal and auxiliary power cables while preserving maintenance access.
Door and Access Systems
Covers terminated harnesses serving doors, access equipment and related control devices.
Seating and Interior Equipment
Protects wiring for seats, lighting and other passenger-compartment electrical systems.
Railway Retrofit Projects
Installs around existing harnesses during vehicle refurbishment, repair and system upgrades.
Provide the railway project, installation location, required EN 45545-2 edition, requirement set, hazard level and document-approval format. Also provide the minimum and maximum harness diameter, routing constraints and cut-length requirements. MJ FLEX should verify that the requested construction is represented by the relevant test report before quotation approval.

Frequently Asked Questions
01. What do R22 and R23 refer to?
They are EN 45545-2 requirement sets used for specified products and installation locations inside railway vehicles. The customer or project specification should identify the applicable requirement.
02. What does HL3 mean?
HL3 is the highest hazard level defined by EN 45545-2. The classification must be linked to the relevant requirement set and tested construction.
03. Can UL 94 V-0 be used instead of EN 45545 HL3?
Not when the railway project specifically requires EN 45545-2. The standards use different test methods and acceptance criteria.
04. Can the sleeve be opened for railway harness maintenance?
Yes. The split self-closing structure permits localized access without removing the entire cable assembly.
05. How is the correct size selected?
Measure the largest installed bundle section and choose a size that maintains at least 35% overlap without excessive tension.
