3 Sigma
Maths and More Maths
This is our system for setting & monitoring the Strength Rating’s as marked on our products in line with the minimum requirements of the relevant European & other Standards, the "3 Sigma Testing" method. Wild Country was one of the first companies in our industry to use this Statistical Quality Control (SQC) technique.
Using test data derived from samples tested to destruction at the design stage we can set the Rated Strength of the product. We then have a system of ongoing Batch Testing which monitors & ensures that the 3 Sigma Rated Strength is maintained & exceeded.
Part of our philosophy at Wild Country is to continue to improve the breaking strength of our products in excess of the standards which may be required. We do this to lessen the chance of failure in situations & conditions which might not be reflected in the standard but which we know as climbers ourselves can cause product failure.
