EN469: 1995 Flame retardant fabric flame retardant protection standard

Protection of water permeation can be used in a substance capable of moisturizing gas. The hydrolyvasive gas protective clothing should be saved in the absence of water vapor through the outer coat. To avoid obstruction of the volatilization of sweat. Appropriate clothing can make firefighters for a long time in danger. However, this is impossible to compare the performance levels achieved in the laboratory and the defense level in practical applications, because changes in high temperature hazard conditions.

Personal additional protective equipment is to protect head, hands, and feet, and a breathing hood must be worn under many fire conditions. Additional equipment must be worn in some specific situations, such as chemical spills. In these cases, the user can combine personal protective equipment and a type of equipment to improve the protection capability together with another equipment, which is necessary for the user.

Because the concept of firefighters is established to establish the level, firefighters need to learn every particular occasion that the clothes apply. He may need to task in specific tasks. Add additional clothing. He should also understand when it is the limits of clothes and what measures should you take. This may define a limited area, which is a lower level of flame-retardant multi-function composite thermal protection level and which reminds the wearer's potential hazard pre-warning.

In this standard, basic safety requirements are established in general fire extinguishing operations, and the level of protective guards can express. This does not hinder the designated clothing in the body's particularly fragile part or has a high performance level when used in specific hazards. For firefighters protective clothing in other standards, there is different levels of performance in special applications. For example, forest fire extinguishing and entering the fire.

This standard is to illustrate test methods and clothes in fire protection work and The minimum requirement when there is heat and fire hazard in related activities. This standard contains the design of general clothes, the minimum performance level of materials. Performance levels may be applied to one or more garments to achieve results. However, it does not include special clothing used in high-risk situations, such as clothing that enters the fire, or long-term clothes for fire protection in the surrounding high temperature conditions, such as the forest fire. It does not include head and hand protection, such as chemical, biochemical, radiation and electricity. These aspects may be described in other standards.

This European standard contains in other versionsThe intended references or unconfigured references will be listed later in the appropriate places and versions of the test. For agreed references, the modifications thereafter are only modifications or modifications to incorporating content in the contained content, and is the revision of these versions to European standards. Basic references will be mentioned in the latest versions.

definitions

as a standard, followed at the definition of

1. Firefighters' protective clothing

Specifies the upper body and lower body of the firefighter, neck, arms and thighs, in addition to head, hands and feet provide protection. 2, outer material

of the outermost material made of protective clothing

3, detachable lining

The lining of the garment is designed to adhere to or wear it in an outer layer, and the purpose is to be induced with heat.

4, ingredient composition

A multi-layer garment is arranged in order in the completed garment structure and includes some lining Binding of fabrics.

5, the composition of multi-layer clothing

A series of clothing in an orderly manner. It may include a multi-layer material that binds to the binding of different levels of a single layer of clothing.

6, ready-to-wear

A single piece of clothing may be a single layer or a multi-layer.

7, underwear

wearing clothes in outer clothes.

8, fastening system

The method of tightening at the opening of the clothes should have more than one safety detachment, For example, the zip chain is tightened and then tightened. This method does not include a side seam. 9, binding

A material is produced from a series of different layers, first and clothing is closely combined when manufacturing. For example, quilted fabric

10, lining

one found in the outermost layer of the multilayer clothes and the innermost layer Layer, not close to the skin of the wearer.

11, the innermost layer lining

The inside of the most inside of the one is found to be found.

12, a moisture-wet protection layer

An a fabric or film applied in one component makes the performance and manufacturer on The pressure of water and the declaration of the penetration of the water vapor are met.

13, hardware

A non-fabric article applied to protective clothing includes those that consist of metal or plastic, such as fasteners, ranking marks, buttons, and the like.

14, integral fusion

Under special test conditions, the substance liquefaction causes extension in its structure or It is shrinking or the flow standard (see 6.5)

15, stitching

two sides of the material or other The method is permanently attached to the clothes.

General design of clothes

1, firefighter's anti-UV cloth protective clothing Should be protected for the fireman's upper body and the lower body, neck and thighs, but the head, hands and feet are outside. It should include

a) single piece of jacket: or

b) one piece of outer wear garment includes a jacket or A pants with a minimum length of a knee is 30 mm: Or

c) Design a series of outer wear clothes to be worn together.

2, the clothes should be designed to minimize the range of activities. If you need it to be consistent with other protective equipment, such as boots, gloves, and breathing hoods. 3, there are multi-layered clothes composition to obtain specific performance level, these layers should be covered with or different clothing

should be clearly Marking them must be clearly taught because they must be used in often. (See Article 9 Ordinance)

4, the side seam should be built into the most minimal loss of strength, protect and maintain the integration of the whole piece of clothing.

5, hardware penetration outer material should not be exposed to the outermost layer of components

6, the fastening system should be completed The performance requirements of the clothes are adapted

7, the clothes should be reversed

The factors required by the user indicate that they are not affected by the clothes. Influence. 8, the end of the sleeves should be designed to protect the wrist and prevent the burning debris. They should not prevent the clothes from being consistent with the protective gloves that should be worn.

9, clothes should also be protectedTo the neck of the wearer

10, the clothes should be proposed and the desired performance level is sufficiently light enough.

11, the clothes should be designed to be easily scrub. 12, any label or sorting should not have a reaction to the performance of the clothes.

Sampling and pre-treatment

1, the selection of the sample should be able to represent materials And employed clothes.

2, the specific number and size of different tests should be dependent on different standards. All tests should be made on materials unless there are other specific criteria. (See 5.4) 3, when the prime layer is exposed, in addition to the spread of the innermost fire (see 6.1) and the water vapor permeation Sexual test (see 7.6), in all surface tests are exposed.

4, the basic safety before the test

Requirements to material tests are (6.1, 6.2, and 6.30) The lateral roller machine should be applied to the delators for five times in soft water in a front loading of the lateral roller machine and dried according to the procedure in ISO6330. Wash should be performed under the conditions of program 2A (60 PLUSMN; 3) and below other specific care labels. According to ISO3175, the material having a dry cleaning tag can only be cleaned five times.
