Ordering Information4.1 Orders for material under this specification shall includethe following information:4.1.1 This specifica

16、tion designation and date of issue,4.1.2 Type S (solid) or Type L (liquid) concentration, gradeand class of calcium chloride required (see Sections 3),4.1.3 Quantity of calcium chloride required,4.1.4 Whether special sampling for inspection is required(see Section 7), and4.1.5 Whether special packag

17、ing and marking is required(see Section 10).5. Chemical Requirements5.1 The calcium chloride shall conform to the followingrequirements for chemical composition, except for the toler-ances stated in 7.2.5.1.1 CaCl2content, %not less than the minimum concen-tration specified, nor greater than the max

18、imum concentrationspecified (when a maximum is specified).5.1.2 Impurity content, %specified relative to the amountof active ingredient (CaCl2) in the product, (see 5.2 forexample calculations):Total alkali chlorides (as NaCl), max, % 6.0Total magnesium as MgCl2, max, % 0.5Calcium hydroxide, max, %

19、0.25.1.2.1 Limits on other impurities shall be specified by thepurchaser according to requirements specific to the end use.5.2 Calculating Impurity Content on an Active IngredientBasis:5.2.1 To calculate the impurity content on an active ingre-dient basis, the impurity percentage measured on an “asr

20、eceived” basis is divided by the CaCl2assay in decimal formas shown in the following example:Product #1CaCl2content, as received basis, % 90Total alkali chlorides (as NaCl), as received basis, % 4.0Total alkali chlorides (as NaCl), active ingredient basis, % (4.0 90)(100)= 4.46. Physical Requirement

21、s6.1 The grading of solid form calcium chloride shall con-form to the requirements of Table 1 for the grade and classspecified in the order.7.
