This standard includes protective clothing, helmets, gloves, footwear, goggles, and chainsaw protectors. It also includes equipment for transporting goods.
This standard does not apply to structural fire protection clothing and equipment.
This standard does not apply to respirators.
All protective equipment and clothing must be labelled in accordance with this standard.
The certification process must be carried out in a laboratory that is certified and accredited according to ISO/IEC 17065 and ISO/IEC 17011
All protective equipment and clothing must comply with the requirements mentioned in the section “Specific requirements for testing protective clothing”
The certification label, pictogram and identification mark must be affixed to, part of, or adjacent to the product label.
The certification label that meets the requirements of the NFPA1977:2016 can no longer be used from the publication of this edition with a margin of 18 months and beyond.
The certificate will not be valid if there are any changes/modifications in the pre-treatment, packaging or any other change that alters the certified item.
Recertification under this standard will be annual.
All parties involved in the manufacturing process must be ISO 9001 accredited (manufacturer, place of manufacture, entity that controls the design of the product, entity that controls the quality of the product, entity that provides the product warranty, entity that appears on the product label and markets it as its own)
If the manufacturer outsources part of the process, this information must be recorded in the ISO package leaflet.
Each garment must bear the corresponding label with a minimum font size of 2.5 mm in height. The pictogram must be at least 6 mm high and placed in a visible place.
All redacted portions of the product label must be printed in at least English. Symbols and pictograms may be used to supplement this information.
The following writing must be added so that it is legible on the product label with a minimum font size of 2.5 mm high.

The manufacturer must provide the following information with each garment:
-Pre-use information (safety considerations, limitations of use, recommendations and restrictions on clothing marking, statement that most performance properties cannot be tested by the user in the field, warranty information); Readiness for use (sizes, storage recommendations, inspection frequency, and details) placement and withdrawal; Proper use in accordance with NFPA 1500 and 29 CFR 1910.132; maintenance and cleaning; Removal and disposal criteria.
-Each opening should have a way to secure it in the closed position.
-The hems of protective clothing on the upper torso shall be designed so that the lower edge can be adjusted to the front and rear lengths specified in this standard. This requirement does not apply to cold weather outerwear.
-All yarns used in the manufacture of the garment must be inherently fire-resistant fibers
-If the garment covers the neck area, it should have a closure system at the neckline.
-Closure systems or fittings must not come into direct contact with the body.
-Torso closure systems in one-piece garments should extend from the upper crotch to the neck.
-In the case of the use of visibility marks, they must be distributed on the outside of the garment offering 360º visibility.
-Jackets, shirts, and one-piece protective clothing should not have bent cuffs. The cuffs must have an adjustable closure system to ensure a secure and snug fit around the wrist when wearing gloves that comply with this standard.
-All pockets must be open to the outside of protective clothing, except for the front waist pockets which must have a cover or closure system.
-Each opening should have a way to secure it in the closed position.
-The hems of protective clothing on the upper torso shall be designed so that the lower edge can be adjusted to the front and rear lengths specified in this standard. This requirement does not apply to cold weather outerwear.
-All yarns used in the manufacture of the garment must be inherently fire-resistant fibers
-If the garment covers the neck area, it should have a closure system at the neckline.
-Closure systems or fittings must not come into direct contact with the body.
-Torso closure systems in one-piece garments should extend from the upper crotch to the neck.
-In the case of the use of visibility marks, they must be distributed on the outside of the garment offering 360º visibility.
-Radiant Heat (RPP) according to ASTM F1939: Clothing fabrics must determine their radiation protection performance and must have an RPP value of at least 7.
Flame resistance according to ASTM D6413/D6413M: Clothing fabrics must determine their radiation protection performance and must have an RPP value of at least 7.
Fabrics, linings, lettering and other materials used in manufacturing (including labels, linings, padding, reinforcements, trims, buckles, emblems, patches and excluding Velcro fasteners, elastics, non-skin contact interfacings) must be individually analyzed for flame resistance and must not have a carbonization length greater than 100 mm, must not have an afterburner of more than 2 seconds, and must not melt or sink.
In the event that the specimens are not large enough to meet the size requirements, their flame resistance must be analyzed as indicated by the test and they must not be completely consumed, must not have a residual flame of more than 2 seconds, and must not melt or sink.
-Heat resistance according to ASTM F2894: Fabrics, interfacings, winter linings, and collar linings must individually meet the heat resistance test and must not shrink by more than 10% in any direction.
-Fabrics, interfacings, winter linings, lettering and other materials used in manufacturing (padding, reinforcements, labels, cuffs, collars, closures, trimmings, buckles, emblems and patches, excluding velcro and elastic fasteners that are not in direct contact with the skin) must individually be heat-resistant and must not melt, sink, separate or ignite. For fabrics, moreover, they cannot be charred
-All clothing fittings should be analyzed individually for heat resistance without being able to light up or lose their functionality.
-Total heat loss according to ASTM F1868: The material/compound used for wilderness clothing, regardless of warm clothing and winter linings, should be analyzed for total heat loss and should not be less than 500 W/m2
-Tear resistance according to ASTM D1424: Openwork fabrics, collar linings and winter linings must individually meet the tear strength with a minimum value of 22N.
-Burst strength according to ASTM D3787 When it comes to knitwear, the burst strength will be determined and must have a minimum value of 225N
-Dimensional stability according to AATCC TM 135 Openwork fabrics, winter linings and collar linings will individually determine the shrinkage strength. The result cannot exceed 5% in any direction.
-Breaking strength according to ASTM D5034: The fabric must meet the breaking strength with a minimum of 225N
-Seam strength according to ASTM D1683/D1683M: For seams of openwork garments or at least one of the openwork fabrics, the minimum seam strength must be 315N in the main seams and 225N in the minor seams.
For sewing in knitted garments, the strength of the seam must be equal to or greater than 180N
In the event that the strength of the fabrics is less than the strength of the seam, provided that the fabric breaks without seam failure below the applicable forces, the breaking strength of the seam shall be considered acceptable.
-Sewing thread melting temperature according to ASTM D7138: The melting temperature of any sewing thread must be determined to be at least 260ºC
-Sewing thread breaking strength according to ASTM D2256/D2256: The breaking strength of any sewing thread must be determined by complying with the requirements of the following table:
-Durability and legibility of labels according to ASTM D4966: Clothing labels must guarantee their legibility and not be broken, as well as they must remain in place and be legible to the naked eye.
-Requirements for fastening tapes according to A-A-55126B: The fastening tape must meet tensile strength, shear strength, and peel strength
-Requirements for Racks per A-A-55634B : Grates must meet the requirements of cross-chain breaking strength, cross-breaking strength of the separation unit, clamping force of the stops, retainers and separating units, operating force, and slide lock strength requirements
