1 ANSI A250.4 Test Procedure and Acceptance Criteria for Physical Endurance for Steel Doors, Frames and Frame Anchors 1

2 Learning Session Description This training aid focuses on the revisions to ANSI A and both the content and intent of this performance standard. The focus is on commercial hollow metal doors, frames and their applicable hardware and how ANSI A250.4 can be used by the design professional in both the selection and specification of commercial door openings. 2

3 Learning Objectives: This session will provide the following learning: Provide an overview and history of ANSI A250.4 Changes in 2011 revision and updates ANSI canvas revision process Reaffirmation of standard Minor changes, content not changed Outline the purpose of A250.4 Why developed Methods of testing How it related to proper selection and usage 3

4 Discussion Items: History Recent Changes Overview and Purpose Test Method 4

5 Discussion Items: History Recent Changes - Overview and Purpose - Test Method 5

6 History First adopted as and SDI Standard First attempt to replicate on-site door usage in operable test environment Door Frame Hardware Provided manufacturers with uniform method of evaluation Life cycle testing of components and assembly 1994 Adopted as ANSI A Re-published and adopted as ANSI A

7 2011 Revisions: Minor Content Changes ANSI requires a ballot on standards every 5 years Hardware reinforcements were removed from test scope Test focus on the door, frame, anchors, and components Title prior to revision: Test Procedure and Acceptance Criteria for Physical Endurance for Steel Doors, Frames, Frame Anchors and Hardware Reinforcings Title after revision: Test Procedure and Acceptance Criteria for Physical Endurance for Steel Doors, Frames and Frame Anchors ANSI A250.4's terminology was revised: Aligned with other A250 standards 7

8 Discussion Items: History Recent Changes Overview and Purpose Test Method 8

9 Overview ANSI A250.4 Purpose: Establishes a performance test method for commercial Hollow Metal openings ANSI Standards Committee A250: Secretariat is the Steel Door Institute Recently approved the revision of ANSI/SDI A250.4, Test Procedure and Acceptance Criteria for Physical Endurance for Steel Doors, Frames and Frame Anchors 9

10 Overview - Purpose Why developed Provided manufacturers with uniform method of evaluation Life cycle testing of components and assembly Methods of testing Two (2) part test procedure: Cycle test at designated level of cycles Twist tests at designated cycle points Operable test: Door cycles with commercial hinges, exit device and closer Replicates on site use and abuse How it related to proper selection and usage Length of cycles tested relate to use and application Provides design professional with guidance 10

11 Overview Performance Test Purpose of the standard: ANSI/SDI A250.4 establishes a performance test method for commercial hollow metal openings Replicates field operating conditions Operable hardware Door swings opens 60 ± 5 Cycles 15 cycles / minute Twist tests at predefined intervals ANSI A250.4 Page #1 11

12 Overview Performance Test Test Apparatus: Test fixture with pneumatic cylinder to cycle the door at designated rates ANSI A250.4 Page #1 12

13 Overview Performance Test Test Apparatus: Test fixture with pneumatic cylinder to cycle the door at designated rates Two part test: Cycle Test Twist Test ANSI A250.4 Page #1 Cycle Test Twist Test 13

14 Overview Performance Test Operable Opening: Exit device Door closer Hinges ANSI A250.4 Page #1 Push side of door Pull side of door 14

15 Overview Performance Test Test specimen: Door: 3070 nominal size door Production doors shall be used Detailed description of the construction ANSI A250.4 Page #2 15

16 Overview Performance Test Test specimen: Frame: Production frame Detailed construction description KD or Welded Anchors: Snap-in or welded ANSI A250.4 Page #2 16

17 Discussion Items: - History - Recent Changes - Overview and Purpose - Test Method 17

18 Purpose: Swing Test Full-sized operable door to simulate actual applications Evaluate door panel degradation Cycles: Level A = 1,000,000 cycles Level B = 500,000 cycles Level C = 250,000 cycles Refer to ANSI A250.8 for guidance in selecting the correct cycle levels in relationship to opening use, application and abuse. 18

19 Swing Test Report Report filled out by technician witnessing test Test can be witnessed and certified by test lab Page #7 Page #8 Page #7 Door Evaluation Page #8 Frame Evaluation 19

20 Twist Test Purpose: Simulate abuse Evaluate door panel degradation Conducted at: 25,000 cycle intervals for the first 100,000 cycles and at 50,000 cycle intervals for the balance of the test. Load pressure: Loads in 30 lb. increments Max 300 lb. load applied Reduce load in 30 lb. increments 20

21 Twist Test Report Plotted curve drawn through the points shall graphically demonstrate the reaction of the door to increasing and decreasing pressures at different cycle intervals. Page #9 21

22 ANSI A250.4 Summary: Recent revisions are minor in nature Performance test to evaluate door, frame and anchor construction Performance levels add rational for: Selection Usage Specification 22
