What FMVSS 205 Covers for Polestar 1 Rear Glass: Safety Glazing Scope and Purpose
When the rear window on a Polestar 1 needs replacement, compliance is part of ordering the right glass. FMVSS 205 (49 CFR 571.205) is the U.S. safety standard for motor-vehicle glazing, and it is written to prevent avoidable injuries and visibility problems related to window glass. It sets baseline requirements for impact performance, fragmentation behavior, and optical quality, and it does so by referencing ANSI/SAE Z26.1. Z26.1 divides glazing into Item designations and marking codes that indicate which parts of a vehicle the glass may be used in, such as a rear window versus a windshield. FMVSS 205 also requires traceable identification on each piece of regulated glazing. On a typical rear glass stamp you will see a DOT symbol, a manufacturer number assigned by NHTSA, and additional markings from the Z26.1 system that signal the glazing type and intended installation area. That stamp is why two pieces of glass that look identical can still be wrong for the vehicle if the certification category does not match. For your Polestar 1, the replacement back glass should be marked as compliant safety glazing, should support the factory defroster grid and any embedded antenna lines, and should match tint and shading so the vehicle retains the intended appearance and light transmission. Bang AutoGlass checks the markings and options before we install and provides mobile rear glass replacement as soon as next day. Most installs take 30 to 45 minutes, followed by a recommended one hour minimum cure time before driving.
Tempered Safety Rear Glass on Polestar 1: What “Tempered” Means and Why It’s Used
Rear windows on a Polestar 1 are typically tempered safety glazing, chosen for how it behaves under load and during breakage. In manufacturing, the glass is heat treated and then quenched so the surfaces lock in compressive stress while the core remains in tension. That stress profile makes the panel stronger than standard glass and helps it tolerate day-to-day impacts like road debris and body flex. If the glass does fail, the same internal stresses drive a controlled fragmentation pattern: the sheet breaks into many small, rounded pieces rather than sharp spears. From a safety standpoint, this reduces deep laceration risk and is one reason regulators and manufacturers prefer tempered glass for rear and side openings. Windshields are usually laminated for different reasons, including retention of the glass sheet after impact and support for airbag deployment zones. For rear glass, tempered construction also integrates well with common features such as defroster grids and privacy shading, and some versions include antenna lines that must align with the vehicle connectors. Because tempered glass cannot be reliably repaired after cracking, correct replacement becomes the priority. Bang AutoGlass installs tempered rear glass for Polestar 1 vehicles with attention to proper adhesion, trim fitment, and the correct safety stamp for the application. We provide mobile replacement service as soon as next day, and every installation is supported by a lifetime workmanship warranty.
Tempered safety rear glass for your Polestar 1 is heat-treated for strength and designed to shatter into small blunt pieces to reduce injury risk.
Unlike minor windshield chips, damaged tempered back glass on a Polestar 1 is usually not repairable and should be replaced to maintain safety and structure.
Bang AutoGlass provides mobile auto glass replacement with OEM-style fit, correct DOT markings, clean adhesive bonding, and restored defroster performance for your Polestar 1.
How to Read the Rear Glass Stamp: DOT Symbol, NHTSA Manufacturer Code, and Certification Marks
The small etching on the back window is one of the most reliable checkpoints when replacing rear glass on a Polestar 1. Under FMVSS 205, compliant glazing must be marked to show certification, traceability, and the glazing category referenced to ANSI/SAE Z26.1. In the field, that means the stamp usually presents a manufacturer name or logo, a DOT symbol, and a DOT number that corresponds to an NHTSA manufacturer code. You will often see additional identifiers such as an AS marking, an Item code, or both, which help signal the intended use location and the performance class of the glazing. For a rear window you commonly also see a clear material description like TEMPERED, confirming it is tempered safety glass rather than laminated. Depending on the producer, the stamp can also include internal part references, plant codes, and date indicators for when the glass was made. Those secondary codes are useful for matching, but the priority is verifying that the replacement carries the required DOT certification marks and the correct Z26.1 based designation for rear window use. This is especially important if your Polestar 1 rear glass includes options like a printed defroster grid, embedded antenna lines, or privacy tint, because the glass must match both the compliance category and the functional pattern. Bang AutoGlass can use a photo of your existing stamp to confirm the correct rear glass and to keep clear documentation of the replacement installed.
ANSI/SAE Z26.1 Item and AS Markings: What the Codes Indicate and Where They Can Be Used
When you look at the stamp on your Polestar 1 rear glass, two different coding systems often show up together: the ANSI/SAE Z26.1 “Item” classification and the “AS” (American Standard) marking. Think of Item numbers as the performance bucket (impact resistance, fragmentation behavior, abrasion, and other tests), and think of the AS marking as the required identification that helps confirm permitted use locations under FMVSS 205. In NHTSA interpretations, FMVSS 205 and ANSI/SAE Z26.1 establish performance requirements for different glazing “Items” and specify where each Item may be used, while the AS codes are designations required on glazing materials under the Z26.1 marking system. On most vehicles, rear windows are tempered safety glazing, so the stamp commonly includes “Tempered” plus an AS code such as AS2 or AS3. One key threshold that shows up in FMVSS 205 guidance is visible light transmittance: NHTSA has stated that material marked AS3 has less than 70% light transmittance and is acceptable only in areas not requisite for driving visibility, and NHTSA interpretations also explain that 70% is the minimum level in areas “requisite for driving visibility” (with what qualifies depending on vehicle type and window location). In other words, the correct AS marking depends on the vehicle class and window location, not just the glass shape. For your Polestar 1 rear glass replacement, we use the stamp to verify the correct compliance category and avoid mismatches that can affect legality, visibility, and inspection outcomes. At Bang AutoGlass, our mobile team confirms the DOT/AS markings and the glazing type before install, so your back glass replacement is correct, compliant, and road-ready.
ANSI/SAE Z26.1 Item numbers classify glazing performance, while AS markings identify the permitted FMVSS 205 use location for your Polestar 1 rear glass.
Rear glass stamps showing tempered safety glazing with AS2 or AS3 help confirm compliance, legality, and visibility requirements for a proper back glass replacement.
AS3 indicates under 70% visible light transmittance and is limited to areas not requisite for driving visibility, so verifying the AS code prevents non-compliant rear glass installs.
Ordering the Correct Polestar 1 Rear Glass: Defroster Grid, Antenna Lines, Tint, and Compliance Checks
Ordering the correct Polestar 1 rear glass is more than picking the right outline or body style. A proper rear windshield replacement has to match the vehicle’s equipment and the compliance markings on the glass. Start with the basics: confirm year, trim, and body configuration (sedan vs. hatchback vs. SUV), then verify whether your rear window has a defroster grid, embedded antenna elements, or both. Many rear windows use thin conductive lines in the glass for the rear defroster, and some vehicles also use embedded metal lines in the rear glass to receive radio signals, so choosing the wrong pattern can mean a dead defroster or poor reception. Next, match the tint and shade: clear vs. privacy/solar tint, and any factory color tone (often green or gray). Also look for hardware details that change part fitment, such as wiper holes, mounting points, molding style, or the location of electrical tabs for the defroster connectors. Finally, do a quick compliance check on the stamp. FMVSS 205 requires aftermarket replacement glazing to meet the requirements applicable to the glazing being replaced, so the replacement rear glass should carry the proper DOT code and ANSI/SAE Z26.1 markings for a rear window installation. If you can, take a photo of the existing stamp and the connector layout before the damaged glass is removed; it speeds up ordering and helps avoid returns. At Bang AutoGlass, we handle these checks for you, source the correct tempered safety rear glass for your Polestar 1, and bring next-day mobile auto glass replacement to your location, with insurance-friendly paperwork when you have comprehensive coverage.
Documentation and Post-Install Verification: Marking Photos, Defroster Testing, and Quality Checks
For a Polestar 1 rear glass replacement, the final step is not just installing the tempered safety glass, it is documenting and verifying that everything works the way the vehicle was designed. We recommend (and we do this automatically) taking clear photos of the old rear glass stamp and the new stamp after installation. FMVSS 205 relies on permanent marking and certification, including the DOT symbol and a manufacturer code mark, so photos create an easy record that the replacement back glass is properly identified. Next comes functional testing. Before trim goes back on, we confirm the defroster tabs are seated correctly and the harness is secure, then we test the rear window defroster to make sure the grid heats evenly and clears fog in a reasonable time. If your Polestar 1 uses embedded antenna lines in the rear glass, verifying the correct glass pattern and connector hookup can also help prevent weak radio signal after a rear windshield replacement. We then complete quality checks that protect you long-term: visual alignment to the body opening, full adhesive bead contact, clean molding fit, and a leak and wind-noise review once the vehicle is reassembled. With Bang AutoGlass, most mobile rear glass replacements take about 30 to 45 minutes, and we recommend at least one hour of cure time for the urethane adhesive before safe drive-away. Your install is backed by our lifetime workmanship warranty, and we can work with any insurance company as long as your policy includes comprehensive coverage, so the process stays simple and professional from start to finish.
