Popis: Aim The primary aim of the exchange was to examine the agreement obtained by using constant-rate-of-loading procedure on 8 in. by 2 in. specimens as tentatively recommended by the International Standardisation Organisation in 1948. Summary The paper deals with the test verdicts, given by eleven laboratories situated in seven countries, on the breaking strength of six kinds of fabric, covering a range from 50 to 500 lb. per in. breaking strength, and consisting of acetate, cotton, nylon, wool and flax fibres. Seven laboratories used the procedure recommended by I.S.O.; two used the secondary I.S.O. procedure of constant-traverse testing, timed to give about one niinute test duration; the remaining two used their ordinary procedure with rapid-traverse pendulum machines. Conclusions The seven sets of verdicts based on the standard procedure had coefficients of variations ranging from one per cent for cotton canvas to nearly three per cent for acetate; the variation, although reasonably good, is appr...
