| 1 | This third revision has been undertaken to align the product standards with current market demands, enhancing its acceptance and relevance. Notable changes include: | |
| 2 | a) The material classification has been restructured into groups based on colours, categories reflecting iron content (expressed as iron (III) oxide), types based on water-soluble matter content and total water-soluble chlorides and sulfates (expressed as Cl– and SO42– ions), grades reflecting residue on sieve, and classes based on the origin of the material. This adjustment replaced the existing seven grades, bringing the standards in line with current market practices. | |
| 3 | b) Additionally, the requirements for each classification and their corresponding test methods have been updated. For instance, the test method for color measurement, staining power, and undertone have been revised, accompanied by updated requirements. | |
| 4 | c) To address health and safety concerns, restrictions have been introduced for lead and toxic heavy metals. | |
| 5 | d) Lastly, various editorial corrections and references have been updated to ensure accuracy and relevance in the revised standards | |
