SPECIFICATIONS FOR SECTIONAL DOORS

Foreword

This foreword is included for information only and is not part of ANSI/DASMA 102, Specifications for Sectional Doors.

This standard was originally developed by the Technical Committee of the National Association of Garage Door Manufacturers and was approved as an American National Standard with the designation ANSI/NAGDM 102. The Door & Access Systems Manufacturers’ Association, International, (DASMA) was formed through the consolidation of two associations that served the garage door and operator industries for many years, NAGDM and the Door Operator & Remote Control Manufacturers Association (DORCMA).

The Technical Committee of the DASMA Commercial & Residential Garage Door Division has reviewed the standard and has incorporated many revisions and updates, effective May 30, 2003. DASMA employs the canvass method to demonstrate consensus and to gain approval as an American National Standard. When printed, this standard was entering the canvass approval process. The ANSI Board of Standards Review granted approval of the edition as an American National Standard on October 22, 2004.

DASMA recognizes the need to periodically review and update this standard. Suggestions for improvement should be forwarded to the Door & Access Systems Manufacturers’ Association, International, 1300 Sumner Avenue, Cleveland, Ohio, 44115-2851.

• ANSI/DASMA 109 Standard Method for Testing Garage Doors: Determination of Cycle Life
• ANSI/DASMA 115 Standard Method for Testing Garage Doors: Determination of Structural Performance Under Missile Impact and Cyclic Wind Pressure 2
• ANSI/DASMA 116 Standard for Section Interfaces on Residential Garage Door Systems
• UL 325 Door, drapery, gate, louver, window operators and systems
• ANSI/ASME B18.6.2 Slotted head cap screws, square head set screws, and slotted headless set screws

4. INSTALLATION/OPERATION

The door system manufacturer shall furnish standard details and instructions for proper installation and operation. Such instructions shall include warnings relative to the installation and operation of the door system.

5. MAINTENANCE

The door system manufacturer shall furnish a listing of those components requiring regular maintenance with instructions and frequencies for such maintenance.

6. DURABILITY

7. IDENTIFICATION

Each door system shall be labeled to identify the name and address of the door system manufacturer.

8. GENERAL REQUIREMENTS

8.1 Hand Chain Hoist Operation

Hand chain hoists shall not be used on standard lift and low headroom applications unless provisions are made to maintain adequate cable tension as specified by the door system manufacturer.

8.2 Power Assisted Operation

8.3 Counterbalance Assemblies

9. LOADS

9.1 Wind Loads

9.2 Dead Loads

$\mathrm{IR}=\frac{\mathrm{MCD}}{d}$

IR = Index Ratio

MCD = Mean Coil Diameter

d = Wire Diameter

9.3.1 Torsion Shafts

FORMULAS

Formulas are used to determine the angular torsional deflection in degrees for tubular wall and solid torque shafts of any wall thickness or shaft diameter. No allowance made for torsional shear modular loss by set screw deformation of tubular shafts, or keyways milled into solid shafts.

Tubular steel shaft formula:

$a=\frac{584\times \mathrm{MIP}\times 12}{(D^4-d^4)\times \mathrm{11,500,000}}$

Solid steel shaft formula:

$a=\frac{584\times \mathrm{MIP}\times 12}{D^4\times \mathrm{11,500,000}}$

Formulas used to determine maximum inch/pound torque limits for a specified number of degrees of torsional deflection per foot of shaft length.

Tubular steel shaft formula:

$\mathrm{MIP}=\frac{a\times (D^4-d^4)\times \mathrm{11,500,000}}{\mathrm{584}\times \mathrm{12}}$

Solid steel shaft formula:

$\mathrm{MIP}=\frac{a\times D^4\times \mathrm{11,500,000}}{\mathrm{584}\times \mathrm{12}}$

Explanation of factors involved in formulas:

a = Angle in degrees deflection per foot of shaft length

MIP = Maximum inch/pounds torque

D⁴ = Outside shaft diameter to the 4th power

d⁴ = Inside shaft diameter to the 4th power

9.3.3 Spring Fittings

10. RESPONSIBILITIES OF OTHERS

10.1 Transmitted Loads

11. DISCLAIMERS
