Description
Agency Approvals
& Self Certifications
3M™ Cold Shrink Quick Splice Low Voltage QSLV-M are open-ended tubular rubber sleeves with sealing mastic on each end which are factory expanded and assembled onto a unique three-core system. Two cores, one on each end, are removed after the 3M QSLV-M insulator has been centered over an inline connector, allowing the ends of the tube to shrink and form a water-resistant seal. The third, center segment of the core remains inside the cold shrink tube, acting as a support structure. Sizing of the cores and tube, along with the sealing mastic on each end, is designed to accommodate the variance in connectors and connector crimping techniques and final dimensions without degrading the seal and insulating characteristics of the EPDM rubber tube, while making core removal easy. Two diameter sizes will cover a range of 1000 volt or less cable from 8 AWG through 500 kcmil, copper and aluminum conductors with crimped connectors.

In aerial applications where intense UV radiation will be common and visual inspection is not possible, it is recommended to overwrap the tubing with Scotch® Super 33+ TM Vinyl Electrical Tape or Scotch® Self-Fusing Silicone Rubber Electrical Tape 70 • Simple hand installation, no tools required
• No heat source, eg. heat guns or torches
• Accommodates wide range of cable sizes, including street lighting • Excellent wet electrical properties
• Good thermal stability during storage and shipping
• Seals tight, retains resiliency and pressure, even after years of aging and exposure • Resists acids and alkalies
• Water resistant. Meets water seal requirements of ANSI C119.1 RoHS
2011/65/EU
"RoHS 2011/65/EU" means that the product or part does not contain any of the substances in excess of the maximum concentration values ("MCVs") in EU Ro HS Directive 2011 /65/EU.

The MCVs are by weight in homogeneous materials. This information represents 3M's knowledge and belief, which may be based in whole or in part on information provided by third party suppliers to 3M.

STRUCTURAL OBSERVATION IS REQUIRED FOR THE STRUCTURAL SYSTEM IN ACCORDANCE WITH THE CBC 2022, SECTION 1704.6. STRUCTURAL OBSERVATION IS THE VISUAL OBSERVATION AT THE

CONSTRUCTION SITE OF THE ELEMENTS AND CONNECTIONS OF THE STRUCTURAL SYSTEM AT

SIGNIFICANT CONSTRUCTION STAGES, AND THE COMPLETE STRUCTURE FOR GENERAL CONFORMANCE TO THE APPROVED PLANS AND SPECIFICATIONS. STRUCTURAL OBSERVATION DOES NOT INCLUDE OR WAIVE THE RESPONSIBILITY FOR THE INSPECTIONS IN SECTION 110 OR THE SPECIAL INSPECTIONS IN 1705 OR OTHER SECTIONS OF THIS CODE.

THE OWNER SHALL EMPLOY A STATE OF CALIFORNIA REGISTERED CIVIL OR STRUCTURAL ENGINEER OR LICENSED ARCHITECT TO PERFORM THE STRUCTURAL OBSERVATION. THE CITY OF

CARLSBAD DEPARTMENT OF BUILDING AND SAFETY REQUIRES THE USE OF THE ENGINEER

OR ARCHITECT, OR HIS/HER DESIGNEE RESPONSIBLE FOR THE STRUCTURAL DESIGN WHO ARE INDEPENDENT OF THE CONTRACTOR.

BETWEEN THE ENGINEER OR ARCHITECT RESPONSIBLE FOR THE STRUCTURAL DESIGN,

STRUCTURAL OBSERVER, CONTRACTOR, AFFECTED SUBCONTRACTORS AND DEPUTY INSPECTORS. THE PURPOSE OF THE MEETING SHALL BE TO IDENTIFY THE MAJOR STRUCTURAL

ELEMENTS AND CONNECTIONS THAT AFFECT THE VERTICAL AND LATERAL LOAD SYSTEMS OF THE STRUCTURE AND TO REVIEW SCHEDULING OF THE REQUIRED OBSERVATIONS. A RECORD OF THE

MEETING SHALL BE INCLUDED IN THE FIRST OBSERVATION REPORT SUBMITTED TO THE BUILDING INSPECTOR.

THE STRUCTURAL OBSERVER SHALL PERFORM SITE VISITS AT THOSE STEPS IN THE PROGRESS

OF THE WORK THAT ALLOW FOR CORRECTION OF DEFICIENCIES WITHOUT SUBSTANTIAL EFFORT OR UNCOVERING OF THE WORK INVOLVED. AT A MINIMUM, THE LISTED SIGNIFICANT CONSTRUCTION STAGES ON THE "STRUCTURAL OBSERVATION/SIGNIFICANT CONSTRUCTION STAGES" FORM REQUIRE A SITE VISIT AND AN OBSERVATION REPORT FROM THE STRUCTURAL OBSERVER.

THE STRUCTURAL OBSERVER SHALL PREPARE A REPORT OF THE "STRUCTURAL OBSERVATION REPORT FORM" FOR EACH SIGNIFICANT STAGE OF CONSTRUCTION OBSERVED. THE ORIGINAL OF

THE STRUCTURAL OBSERVATION REPORT SHALL BE SENT TO THE BUILDING INSPECTOR'S OFFICE

AND SHALL BE SIGNED AND SEALED (WET STAMP) BY THE RESPONSIBLE STRUCTURAL OBSERVER OF RECORD. ONE COPY OF THE OBSERVATION REPORT SHALL BE ATTACHED TO THE APPROVED PLANS. THE COPY ATTACHED TO THE PLANS SHALL BE SIGNED AND SEALED (WET STAMP) BY THE RESPONSIBLE STRUCTURAL OBSERVER OR THEIR DESIGNEE. COPIES OF THE REPORT SHALL ALSO BE GIVEN TO THE OWNER, CONTRACTOR, AND DEPUTY INSPECTOR. ANY DEFICIENCY

NOTED ON THE OBSERVATION REPORT WILL BECOME THE RESPONSIBILITY OF THE STRUCTURAL

ENGINEER OR ARCHITECT OF RECORD TO VERIFY ITS COMPLETION BY THE STRUCTURAL OBSERVER.

A FINAL OBSERVATION REPORT MUST BE SUBMITTED WHICH SHOWS THAT ALL OBSERVED

DEFICIENCIES WERE RESOLVED AND STRUCTURAL SYSTEM GENERALLY CONFORMS WITH THE APPROVED PLANS AND SPECIFICATIONS. THE CITY OF CARLSBAD DEPARTMENT OF

BUILDING SAFETY WILL NOT ACCEPT THE STRUCTURAL WORK WITHOUT THE FINAL OBSERVATION

REPORT AND THE CORRECTION OF SPECIFIC DEFICIENCIES NOTED DURING NORMAL BUILDING INSPECTION.

THE STRUCTURAL OBSERVER OF RECORD SHALL PROVIDE THE ORIGINAL STAMPED AND SIGNED "STRUCTURAL OBSERVATION REPORT FORM" TO THE THE CITY OF CARLSBAD DEPARTMENT OF BUILDING AND SAFETY BUILDING INSPECTOR.

A. POST-INSTALLED ANCHOR IN CONCRETE
B. EPOXY ANCHOR IN CONCRETE

4. THE TESTING TORQUES FOR POST-INSTALLED ANCHORS SHALL BE BASED ON THE

MANUFACTURER'S RECOMMENDED INSTALLATION TORQUE AS APPROVED IN AN ICC-ES EVALUATION REPORT UNLESS OTHERWISE NOTED. (CONFORM TO REQUIREMENTS OF CBC 2022, SECTION 1901.3.4.4).

5. THE TESTING FORCES FOR POST-INSTALLED ADHESIVE ANCHORS SHALL BE BASED ON ONE AND A QUARTER (1¼) TIMES THE MAXIMUM DESIGN STRENGTH OF ANCHORS AS PROVIDED IN

AN APPROVED TEST REPORT USING CRITERIA ADOPTED IN THIS CODE OR DETERMINED IN ACCORDANCE WITH APPENDIX D OF ACI 318. TENSION TEST LOAD NEED NOT EXCEED 80 PERCENT OF THE NOMINAL YIELD STRENGTH OF THE ANCHOR ELEMENT (=0.8Asefya). (CONFORM TO REQUIREMENTS OF CBC 2022, SECTION 1901.3.4.4)

6. ACCEPTANCE CRITERIA FOR POST INSTALLED ANCHORS SHALL BE BASED ON ICC-ESR OR MANUFACTURER'S WRITTEN INSTRUCTION. FIELD TEST SHALL SATISFY THE MINIMUM REQUIREMENTS PER CBC 2022, SECTION 1901.3.4.3 AND 1901.3.4.5.
