ANSI 107:2020

HVSA types are designated by the work environment in which the user performs a task.

• Clothing includes, but is not limited to, clothing such as vests, jackets, pants, shirts, rainwear, and coveralls.
• Type O
• Occupational HVSA for Off-Highway Use
• Type R (“highway”): Occupational HVSA for highway use
• Type P (“Public Safety”): Occupational HVSA for emergency and incident response personnel and law enforcement personnel

The performance classes present in each type of HVSA are specified in terms of the minimum area of high visibility materials to be incorporated. Performance classes offer a range of design options that correspond to the needs of the user in the anticipated risk environment. The O type includes one performance class, and the R type and P type each have two performance classes.

• Performance Class 1 (Type O)
• visually differentiate the user from non-complex work environments, in scenarios where the hazards of being struck will not approach highway speeds and therefore detection and identification operating distances.
• Performance Class 2 (Type R or P)
• it can allow design opportunities to define the human form more effectively. Performance Class 2 HVSA has the potential to provide longer detection and identification distances, and increased visibility performance compared to Performance Class 1 HVSA.
• Efficiency Class 3 (Type R or P)
• can offer increased visibility to the wearer both on complex backgrounds and through a full range of body motions by mandatory placement of background, retro-reflective, and performance blend materials on the sleeves and pant legs (if present) . Regardless of the area of materials used, a sleeveless garment or vest by itself will not be considered Performance Class 3.
• Pants, coveralls, shorts, and leggings will be designated Class E.
• they should not be used alone for the purpose of meeting HVSA PPE requirements.
• They must not be used alone for the purpose of meeting PPE requirements and will be classified class 3.

• The parts of the garment that come into contact with the end user must not have any rough edges, sharp edges or protrusions that could cause irritation or injury.
• The garment must be designed for correct fit and positioning on the wearer and must be designed to ensure that it remains in place during the expected period of use.

HVSA will incorporate the minimum material areas specified in Table 1.

• The bands will be placed between the elbow and the shoulder. Lower bands may be placed between the elbow and wrist, but must be at least 2 inches (50 mm) above the bottom of the sleeve.
• Gaps in retroreflective materials should be no more than 2 inches (50 mm) horizontally to allow for clamping or seam allowance.
• 360° visibility
  Retro-reflective or blended performance and background materials for all garment types and performance classes shall be placed on the articles in such a manner as to provide 360° visibility of the wearer at all viewing angles in a horizontal plane.
• Manufacturing class 1
  This band must completely encircle the torso and must be a minimum of 25mm (1 inch) wide.
• Manufacturing class 2
  This band must completely encircle the torso and must be a minimum of 35 mm (1.38 in.) wide for Type R and 50 mm (2 in.) wide for Type P. In addition, it must be a minimum of 150 cm² (23.3 in²). present in the shoulder area for HV PPE where the surrounding bands are not present on the sleeves.
• Manufacturing class 3
  This band must completely encircle the torso and each arm and must be a minimum of 50 mm (2 inches) wide.
• Manufacturing class E
  This band will completely encircle each leg and be a minimum of 50mm (2 inches) wide.

• Garments must be balanced in design such that not less than 40% of the required minimum amount of background and blend performance or retroreflective materials specified in Table 1 is present on both the front and back when worn. lay flat.
• Shoulder area
  HV PPE without retroreflective or performance blend material surrounding the arm shall have a minimum of 150 cm2 (23.3 in.2) of retroreflective or performance blend material in the shoulder area to provide 180° visibility of the user.

• Pockets, name panels, lettering and logos must not create gaps of more than 50mm horizontally.

• Color:(Refer to the coordinate char
  • The average value of the total luminance factor and the chromaticity coordinates of the combined performance and background material must meet the requirements of the Table above
  • Color fastness of the combined rendering and background materials after xenon testing must be within one of the areas defined by the coordinates in Table 2 and the total luminance factor (Y expressed as porcentaje) no debe ser menor que los valores mínimos correspondientes en la Tabla anterior
  • The color fastness to rubbing, both dry and wet, must be at least a 3.0 grade according to the Gray Scale.
  • Color fastness to perspiration must be at least a 4.0 grade for color change according to the Gray Scale
  • Color fastness: washed the specimens shall be hung to dry in the air at a temperature not exceeding 60ºC (140ºF) with the parts in contact only at the seam lines.

The retroreflection coefficient RA, measured at an angle of observation of 0.20° [12′] and an angle of entry of 5, should not be less than 100 cd/(lx • m2) in one of the two orientations described in Section 10.3 and must not be less than 75 cd/(lx • m2) in the other orientation.
