(b) An article consisting of at least 985/1000ths parts  of  platinum, iridium,  palladium,  ruthenium,  rhodium and/or osmium, where solder is not used and at least 950/1000ths parts of  the  said  metal  or  metals where  solder  is  used,  and provided further that at least 750/1000ths parts of said article are  pure  platinum,  may  be  marked  "platinum," provided  immediately preceding the mark "platinum" there is the name or abbreviation as hereinafter  provided,  of  either  iridium,  palladium, ruthenium,   rhodium   and/or   osmium,   which   ever  of  said  metals predominates, and provided further that such predominating  other  metal must be more than 50/1000ths parts of the entire article.  (c)  An  article consisting of at least 985/1000ths parts of platinum, iridium, palladium, ruthenium, rhodium and/or osmium,  where  solder  is not  used  and at least 950/1000ths parts of said metals where solder is used, provided more than 500/1000ths parts of said  article  consist  of pure  platinum,  may  be  marked with the word "platinum," provided that said  word  is  immediately  preceded   by   a   decimal   fraction   in one-thousandths  showing  the  platinum  content  in  proportion  to the content of the entire article,  and  further  provided  that  said  mark "platinum" be followed by the name or abbreviation as herein allowed, of such  one  or  more of the following metals, to wit: iridium, palladium, ruthenium, rhodium and/or osmium, that may be present in the article  in quantity  of  more than 50/1000ths parts of the entire article. The name of such other metal or metals other than platinum, however,  shall  each be immediately preceded by a decimal fraction in one-thousandths showing the  content  of  such other metal or metals in proportion to the entire article, as for example, 600 plat., 350 pall., or 500 plat., 200  pall., 150 ruth., 100 rhod.  (d)  An  article  consisting  of  950/1000ths  parts  of the following metals:  platinum, iridium, palladium, ruthenium, rhodium, and/or osmium with less than 500/1000ths parts of the  entire  article  consisting  of pure   platinum,  may  be  marked  with  the  name  iridium,  palladium, ruthenium, rhodium and/or osmium, which ever predominates  in  the  said article  but  in  no  event with the mark "platinum," provided, however, that the quantity of such metal other than platinum so marked,  must  be marked  in  decimal  thousandths,  and provided further that the name of such metal other than platinum so used  must  be  spelled  out  in  full irrespective of any other provisions of this article to the contrary.  (e)  An article composed of platinum and gold which resembles, appears or purports to be platinum, may be marked with  a  karat  mark  and  the platinum mark, provided:   1.  The  platinum  in such article shall be at least 985/1000ths parts pure platinum; and   2. The fineness of  the  gold  in  such  article  shall  be  correctly described by the karat mark of said gold; and   3.  The  percentage  of platinum in such article shall be no less than five per centum in weight of the total weight of the article; and    4. The mark shall be so applied that the karat mark shall  immediately precede  the  platinum  mark,  as  for  example,  "14K & Plat.", "18 K & Plat.", as the case may be, it being expressly provided that in case the percentage of platinum exceeds the five per centum provided herein,  the quality  mark  may  also  include  a  declaration  of  the percentage of platinum, as for example, "18 K & 1/10th Plat.", or "14 K &  1/8  Plat." or as the case may be.  (f)  An  article  composed of platinum and any other material or metal not resembling, appearing or purporting to be platinum,  may  be  marked with  the  quality  mark platinum provided all parts or portions of such article resembling  or  appearing  or  purporting  to  be  platinum,  or reasonably  purporting to be described as platinum by said quality mark, shall be at least 985/1000ths parts pure platinum.
