Webbing samples to make your future choice easy

Haven't had the chance yet to test or feel the webbing you heard so much about? 
Don't worry, our 10cm WEBBING SAMPLES will make your choice easier and will help you understand best the structure and type of webbing you may want to invest in. 

If as thick and heavy as the JUMBO, think light and strong like the SKY DIAMOND or super versatile and comfort like the JOKER, the WEBBING SAMPLES will definitely help you better understand and serve as a little guide to your big future slackline. 

You can choose one or several samples, make keychain accessory or some fun decoration from it later. 

SAMPLE
    What is the 3 SIGMA MBS in the product data sheet?

    Hi! Does the 50 meter longline kit come with webbing that has 2 sewn loops? Thanks! SIGMA is an element of statistical calculations, which allows to display a products’ guaranteed strength value throughout its manufacturing process. Therefore, it is related to product safety.  

    During the testing process, the greater the differences between the 10 recorded values, the higher turns out the sigma value.

    For example, for 10 carabiners tested, their ten recorded values are usually different and not the exact same:

    24,9 | 25,9 | 26,2 | 25,6 | 25,8 | 24,7 | 25,5 | 24,7 | 26,0 | 25,7 kN

    So which value to take into account to display the MBS (Minimum Breaking Strength) value? 

    We first calculate the average:

    (24,9 + 25,9 + 26,2 + 25,6 + 25,8 + 24,7 + 25,5 + 24,7 + 26,0 + 25,7) / 10 = 25,5 kN

    We then calculate the variance:

    24,9 - 25,5 = - 0,6    (-0,6)2 = 0,36

    25,9 - 25,5 = - 0,4    ( 0,4)2 = 0,16

    ...and so on for the 10 measured values.

    We add those 10 results:

    0,36 + 0,16 + 0,49 + 0,01 + 0,09 + 0,64 + 0,064 + 0,25 + 0,04 = 2,68

    And we create the average:

    2,68 / 10 = 0,268

    The variance is even to : 0,268

    SIGMA (standard deviation) = square root of 0,268 = 0,5176

    The maximum value displayed on the carabiner would be:

    average of 10 carabiners = 25,5 kN

    SIGMA = - 0,5176

    ____________________________

    Displayed Value = 24,0724 kN

     

    What you should know in particular about the 3 SIGMA safety margin? 

    We use the 3 SIGMA method to calculate the MBS. 

    We multiply the SIGMA for 3 (this is why it is called “3 SIGMA”) to boost the prudency in the MBS calculation.

    Taking the 10 previous carabiners as an example:

    The average of those 10 carabieners is 25,5kN

    3 SIGMA (3 x 0,5176) = - 1,5528

    _____________________________

    Displayed value = 23,0472 kN
