Statement of Problem and Substantiation for Public Comment

This standard was formerly the Federal Standard 751 for Stitches and Seams before being transitioned into an ASTM Standard in 1995. It provides a ready reference to better understand how any sewn textile product, garment, or PPE is constructed or needs to be repaired. In addition to complete descriptions and drawings of every type of stitch formation (sewing thread configurations) there are line drawings that show the wide range of seam types (fabric configurations) that can be made so that two or more planar structures can be joined together.

The standard also has drawings and descriptions of bartacks, buttonholes, and zig-zag stitches.

The standard also includes vocabulary that identifies terms, such as overedged seam, lapped seams, lapped-felled seams, chainstitch, safetystitch, lockstitch, and many more. This standard can provide useful reference information for all parties that purchase, manufacture, clean and maintain, or inspect Wildland firefighting PPE.

The specific cross references to this standards will be shown later in the standard.

A) This is the ASTM Standard developed when Federal Standard 191A, Test Method 1534 was transitioned in 2005. The standard allows for the use of two instruments to determine the temperature at which a solid becomes a liquid. Test Method I uses a Differential Scanning Calorimetry (DSC) instrument. Test Method II uses the same instrument as used in the original Federal Standard.

The specific cross reference will be shown later in the standard.

B) The Federal Standard and Test Method in Section 8.9 were discontinued in 2005. The recommended change to Section 2.3.4 would support the deletion of section 8.9.

Commercial Item Description A-A-55126B, Fastener Tape, Hook and Loop, Synthetic, 7 September 2006.

Commercial Item Description, A-A-55220, Para-aramid, Continous Filament

Commercial Item Description A-A- 55634A, Zippers (Fasteners, Slide Interlocking), 23 March 2004.

Military Specification MIL-DTL-10884H, Fastener, Snap, 20 July 2005.


Starting in the 1990's, the U.S. Government transitioned from military specifications to CID's (performance based documents) so that purchases could made from commercial inventories. These inventories would be obligated to meet consensus performance standards that had been agreed to by industry, the Defense Logistics Agency (DLA), and Natick R&D Center.

Every CID identifies multiple performance requirements that require using different types of measurements. While CID, A-A-55220 measures; 1) break strength (D204), 2) yardage (D1907), 3) elongation (D204), 4) yarn size (D204), and 5) melting (D7138), the only test currently required for NFPA 1977 is the melting test that uses D7138.

Commercial Item Description A-A-55195, Para-Aramid, Spun Thread, Type I Normal Performance, Type IIHigh Performance




Starting in the 1990's, the U.S. Government transitioned from military specifications to CID's (performance based documents) so that purchases could be made from commercial inventories. These inventories would be obligated to meet consensus performance standards that had been agreed to by industry, the Defense Logistics Agency (DLA), and Natick R&D Center.

Every CID identifies multiple performance requirements that require using different types of measurements. While CID, A-A-55195 measures: 1) break strength (D204), 2) yardage (D1907), 3) elongation (D204), 4 yarn size (D204) and 5) melting (D7138), the only test currently required for NFPA 1977 is the melting test that uses D7138.

The protective driver's glove, that is styled similar to the military combat glove, uses tex size 40 para-aramid sewing thread that demonstrates greater than 9 lbf (40N) break strength. This break strength enables the driver of heavy equipment to have good tactility to better control the vehicle; the protective driver's gloves will also demonstrate good wear and abrasion resistance, similar to how they served the military in Iraq and Afghanistan.

Commercial Item Description A-A-55217, Aramid, Spun Thread, Type I Normal Performance, Type II HighPerformance




Starting in the 1990's, the U.S. Government transitioned from military specifications to CID's (performance based documents) so that purchases could be made from commercial inventories. These inventories would be obligated to meet consensus performance standards that had been agreed to by industry, the Defense Logistics Agency (DLA), and Natick R&D center.

Every CID identifies multiple performance requirements that require using different types of measurements. While CID, A-A-55217 uses many different ASTM test methods to measure: 1) break strength (D204), 2) yardage (1907), 3) elongation (D204), 4) yarn size (D204) and 5) melting (D7138), the only test currently required for NFPA 1977 is melting test that uses D7138.

This is inconsistent when the fabrics being sewn together are tested for both break strength and exposure to high heat. The data this CID contains can be used with data from D6193, Standard Practice for Seam and Stitches, to estimate how the major seam strength of 70 lbf (310N) and the minor seam strength of 50 lbf (220N) can be achieved with certain tex sizes of sewing thread, using specific seam configurations, and a certain number of stitches per inch.

File Name Description Approved

1977_PC_6.pdf 1977, Public Comment # 6, substantiation continued


Data that is readily available and well known show that a properly designed seam construction, using the correct tex size of sewing thread, and the proper number of stitches per inch can meet the seam strength performance requirements for both "major" seams and "minor" seams so that only failure of the stitching will occur along the stitchline when stressed during testing.

Any member of a manufacturer's staff; designer, product specialists, production engineer, and quality control personnel - who has learned these formulas, (to be found on following page), and their interpretation, can easily calculate and approximate point of failure when fabric sections are sewn together.

7.1.9.3

Where the fabric strength is less than the required seam strength specified in 7.1.9.1 , providing the fabricfails without failure of the seam below the applicable forces specified in 7.1.9.1 , the seam breakingstrength shall be considered acceptable

Fabrics which cannot be used to build sewn seam constructions that meet both the major seam strengthperformance of 315N (70 lbf) and the minor seam strength performance requirement of 225N (50 lbf), anddemonstrate a seam failure, only along the stitchline, shall not be used for the manufacture of garments .


Failure along the stitchline enables garment to be repaired. Fabric failure requires that garment needs to be replaced.

As shown in 7.1.9.1 the different elements that are used to calculate the estimated seam strength can also be useful factors in making a determination about fabric suitability.

CC NOTE: The following CC Note No. 39 appeared in the First Draft Report as First Revision No. 39, and is also related to Public Input No. 90.

The Correlating Committee directs the Technical Committee on Wildland Fire Fighting Protective Clothing and Equipment to validate the new [or significantly revised] test method through the following:

1. Provide a rationale with supporting evidence that substantiates the need or the rationale for establishing new test methods or criteria or for revising existing test methods or criteria in terms of field relevance, fire service needs, safety concerns, recognition of new product technology, accounting for advances in testing technology, or accomplishing other clearly stated objectives.

Examples of supporting evidence can include the documentation of specific safety issues that have been identified by end user or other groups, which may include statistics on the number of incidents or highlight specific cases where the issues have arisen. Other forms of supporting evidence can include aspects of existing requirements that unduly prevent the proper testing or consideration of new product technologies because the existing test methods or criteria are found to be design-restrictive, or information that shows that new test methods have become available that provide more reliable or relevant forms of evaluation for the specific product property or attribute under consideration. The provision of scientific papers, test data, or statistics provides a more robust justification for supporting evidence.

2. Conduct an assessment to determine the potential impact of the new or significantly revised test methods or criteria on products that have already been certified or fielded.

The nature of this requirement is to have the TC assess what the anticipated impact of the new or modified requirements are relative to specific products. It is not the intent to identify specific products that might be excluded by a new or modified requirement, but rather for the submitter to provide an analysis for the types of products that might be affected, with an indication as to why the affected products do not provide adequate performance.

3. Establish Intra-laboratory repeatability and inter-laboratory reproducibility for new or significantly revised test methods. Where possible, test methods shall include procedures for their calibration. The principal certification organizations and their laboratories shall formally affirm to the TC that the tests can be conducted reliably as proposed at least by the time of the second draft.

An essential part of the validation process is to include an assessment of the repeatability (intra-laboratory precision) and reproducibility (inter-laboratory precision) of any new test method or significant modification of an existing test method. This information is important for establishing the reliability of the test method and should, as a minimum, include those laboratories that provide certification services for the relevant product standard. This information may also be useful in setting specific criteria to account for expected test method variability.

4. Establish the relevance of test methods and any associated criteria through a determination of how proposed or significantly revised test methods identify meaningful differences in product performance consistent with field performance.

Attempts should be made to determine the degree to which new or significantly revised test methods identify meaningful differences in product performance or relate to the field performance of products. One recommended approach is to identify product types that are considered to be unsuitable based on end user field experience and evaluate those products alongside other products to determine if the test method suitably identifies meaningful differences in performance consistent with observed field performance. Another approach is to demonstrate the


24 of 98 2/3/2015 10:49 AM

impact and relevance of test results for products through carefully designed experiments carried out in the field. Lastly, one additional approach is to relate proposed criteria to specific safety levels that can be documented through scientific or other reasonably based field investigative work.

5. Provide test data and any other supporting documentation to the members of the respective TC and the CC, or any individuals who may request this information.

Access to the information on which new or significantly revised test methods and criteria are based should be available to all parties seeking this information, including TC members, CC members, and individuals outside the committee process (through the NFPA). Supporting documentation that includes, but is not limited to, proposed new or modified methodology/criteria with justification statements, supporting evidence, test data, references to published papers or statistics, inter-laboratory test results, and other information should be maintained by the TC as part of meeting minutes or made available elsewhere on the NFPA TC website page.

6. Provide at least one of the following visual illustrations of the proposed test equipment and test material(s) to the respective TC and CC:

a. Video(s)

b. Photo(s)

c. Drawings(s)

The visual illustrations shall be provided along with the submittal.

Visual illustrations help TC and CC members better understand the proposed new test or modified test.

Resolution: CC Note No. 2 appeared in the First Draft Report as First Revision No. 40. The Technical Committeereviewed the CC Note and responded to the questions as follows: 1. The TC is doing this to beconsistent with NFPA 1951 and NFPA 1971.The new test replaces a less variable and subjectivemethod for torsion grip. 2. Testing was conducted on known certified models and no adverse effectswere noted. 3. This method is already being performed by multiple testing laboratories. 4.

Statement: The Technical Committee created this second revision to establish minimum standards tomaintain the current quality of sewing threads that are used for the products addressed by thisstandard.

1. Specify the range of Tex thread size that can be used because this is the range specified in thespecification

2. Add a minimum breaking strength requirement to ensure that the minimum requirements formajor seams can be met

3. Verify that excessive thread elongation does not result in diminished seam and garmentperformance properties not evaluated by seam strength

4. Verify that sewing thread will not melt and result in seam failure

7.3.11

Protective work gloves shall be tested using the torque test specified in Section 8.34, and shall have anaverage percent of bare-handed control not less than 80 percent.


CC Note: The following CC Note No. 2 appeared in the First Draft Report as First Revision No. 40









Attempts should be made to determine the degree to which new or significantly revised test methods identify meaningful differences in product performance or relate to the field performance of products. One recommended approach is to identify product types that are considered to be unsuitable based on end user field experience and evaluate those products alongside other products to determine if the test method suitably identifies meaningful differences in performance consistent with observed field performance. Another approach is to demonstrate the impact and relevance of test results for products through carefully designed experiments carried out in the field.


27 of 98 2/3/2015 10:49 AM

Lastly, one additional approach is to relate proposed criteria to specific safety levels that can be documented through scientific or other reasonably based field investigative work.

Attempts should be made to determine the degree to which new or significantly revised test methods identify meaningful differences in product performance or relate to the field performance of products. One recommended approach is to identify product types that are considered to be unsuitable based on end user field experience and evaluate those products alongside other products to determine if the test method suitably identifies meaningful differences in performance consistent with observed field performance. Another approach is to demonstrate the impact and relevance of test results for products through carefully designed experiments carried out in the field. Lastly, one additional approach is to relate proposed criteria to specific safety levels that can be documented through scientific or other reasonably based field investigative work.

The average temperature at 30 seconds of exposure for each area of the footwear insole for all specimensshall also be calculated, recorded, and reported.


8.28.7.1

The average temperature at 30 seconds of exposure for each area of the insole for all specimens shall beused to determine pass or fail performance.


The original PI 81 was intended to make NFPA 1977 consistent with 1971. During TC discussions at the FR meeting, the TC agreed that the increased temperature and shorter exposure period.was to be maintained for 1977. This was due to the hazard of stepping into a high temperature depression. Since the higher temperature and short duration were maintained, the original language should be as well. The ball of the foot has shown to be the most critical area, and there is little information to be gained by the use of additional thermocouples over a short period of time. Additionally, electric hotplates cannot be used reliably at 500C.

An essential part of the validation process is to include an assessment of the repeatability (intra-laboratory precision) and reproducibility (inter-laboratory precision) of any new test method or significant modification of an existing test method. This information is important for establishing the reliability of the test method and should, as a minimum, include those laboratories that provide certification services for the relevant product standard. This
