Marking size sleeping bags. Standard EN 13537: 2012

In 2012 the European standard EN 13537, the regulatory requirements for sleeping bags, there have been a number of changes compared to the standard EN 13537: 2002. Changes related to, including, methods of determining the size of a sleeping bag.

The purpose of the revision was to simplify the standard by eliminating requirements and test methods that have not been proven and that do not contribute to the quality of the manufacturing of sleeping bags. Since the last edition of the standard EN 13537, goods on the market developed to suit the changing needs of the buyer. When revising the standard, the intention of the Committee was to reflect the ever-changing needs, and at the same time not to make the standard limitation for the development of new technologies. The document contains a number of requirements that are in accordance with the standard must be met by manufacturers.

  1. Mechanical abrasion resistance of sleeping bags - at least 20 000 cycles
  2. The tensile strength of the outer tissues must be at least 10 N
  3. The composition of the filler is determined in accordance with EN 12934
  4. The hygienic condition of the filler must meet the requirements of EN 12935
  5. The amount of synthetic fibers protruding through the fabric of sleeping bags should not exceed 30 PCs. for each pillow
  6. The color fastness when washed in accordance with EN ISO 105-X12
  7. The mass of filler should not deviate by more than ± 7% of the declared nominal.

Separately consider the requirements of the European EN 13537 standard for sleeping bags sizes.

The designation is carried out according to the internal dimensions of the sleeping bag.

1)Inner length of a sleeping bag.

The length of the sleeping bag allows an accuracy of the specified size to within ± 3 cm. Measurement according to European standard EN 13537 is made with an inside-out sleeping bag by measuring the distance between the stitches from the heel of the foot to the top of the sleeping bag, without the use of any power to increase the size a sleeping bag.

2) the Internal width of a sleeping bag.

Maximum width inside of a sleeping bag should be measured with an accuracy of ± 2 cm. Measurement is made with an inside-out sleeping bag. The size is determined by circumference at the widest point, not stretching the material, followed by dividing the size of the circle by 2. If the maximum width of a sleeping bag is not in the chest area, this should be noted on the label. If the sleeping bag has elastic seams, that would require them to expand before measuring, you can use a spring scale.

3) Width on the foot.

Width in feet inside of a sleeping bag should be measured with an accuracy of ± 2 cm. Measurement is performed by eversion of the sleeping bag inside out and measure the circumference at the distance (30 ± 1) cm from the heel seam to the side of the head of the sleeping bag. The circle is divided in half to get the width of a sleeping bag. If the sleeping bag has elastic seams that would expand before measuring, you can use a spring scale.
