Testing & Quality
Turns the readings from a set of test specimens into the mean, sample standard deviation, CV% and a confidence interval built on the correct t value for the specimen count – the summary every textile test report has to carry, whatever property was measured.
Calculator
Testing & Quality
Places a laboratory result against a restricted substance limit with its expanded uncertainty, applies a guard band to give an acceptance limit, converts the result between mg/kg, ppb and percent, and reports the margin against a later limit that a stepped-down threshold will bring.
Calculator
Testing & Quality
Compares a declared fibre composition against a test result fibre by fibre, applies the tolerance as percentage points of total fibre weight rather than as a percentage of the declared figure, shows the band each declaration allows, and removes the tolerance where the label claims a single fibre.
Calculator
Testing & Quality
Computes warp, weft and Peirce cloth cover factors from sett and count, takes the worse of the two measured slippage forces against specification, and solves the cover factor and pick density a target resistance would actually require.
Calculator
Testing & Quality
Normalises the three moisture management tester outputs onto their index scales, blends them into the OMMC with the standard weighting, returns the grade, and identifies which index is limiting and what perfecting it alone would be worth.
Calculator
Testing & Quality
Places measured exposure hours on the logarithmic blue wool scale, returning the achieved rating and the standard it rounds to, the hours a target grade demands, the margin either way and the equivalent AATCC fading units.
Calculator
Testing & Quality
Converts fabric weight between GSM, ounces per square yard, grams per linear metre and ounces per linear yard; yarn tenacity between centinewtons per tex, grams per denier, breaking length and true stress in megapascals; and yarn length between metres per kilogram and yards per pound.
Calculator
Testing & Quality
Converts fabric or wadding thickness and thermal conductivity into thermal resistance, then into TOG, clo and imperial R-value, the insulation scales used to specify winterwear and bedding.
Calculator
Testing & Quality
Compares tear strength against tensile strength to expose fabrics that test strong in tension but tear easily, and normalises both by fabric weight so different constructions can be judged fairly.
Calculator
Testing & Quality
Calculates seam efficiency from seam and fabric breaking strength, the absolute strength lost at the seam, and the seam strength a target efficiency specification would demand.
