4 MEASURING LOAD
The measuring load is determined as five times the weight of a 10 ft strand rounded (0 the nearest 100 lb. This value is then converted o kilonewtons for (he metric equivalent.
5 STRAND LENGTH TOLERANCE
1ow length of new chains subjected to the specified measuring load must fall within the plus and minus tolerances shown in Table I. Specific maximum and minimum strand lengths are shown in Tables 2. 3, and 4 for each chain.
Maximum and minimum strand tolerances for the given number of pitches in a measuring strand are shown in Table I.
6 DIMENSIONS FOR CHAIN LINKS
To assure interchangeability of links as produced by difkren makers of chains, standard maximum and minimum dimensions are adopted. They are nt* actual dimensions used in inanufacwring. hut limiting dimensions. maximum or minimum, required to assure the desired interchangeability.
11w metric equivalent dimensions are for reference

9 CHAIN ASSEMBLY
See Fig. 5 and Tabks 2. 3. and 4.
10 SPROCKETS
Two sprocket tooth forms are included: Forms A and B. Tbc major difference between thcsc two forms is in the method of gencrating the tooth form. Form A produces a curved tooth face and Form B a straight tooth lace. Either form may be used. See Tables 5. 6. and 7. and Figs. 6 and 7.
10.1 Sprocket Tooth Form Data
Root diameter (D,), pockct radius (I,). and outside diameter (D,,) must not exceed the values obtained by the formulae. Oversize dimensions may cause improper chain and sprocket interaction and excessive chain loads (see Fig. 6).
In some cases the outside diameter (1),.J may be limited by special attachments mounted on the chain. For this reason, the outside diameter (Di,) should be checked to assure that interference does not exist. I),, obtained by the formula should he rounded oft to the next smallest 1/8 in. (3 mm).
Chain clearance circle (Ce) established by the formula is the maximum and will provide clearance under most conditions, However, the value obtained by the formula should be checked to assure that a given hub diameter does not interfere with chain attachments.
