## Report on Bureau of Indian Standards Notification Regarding Plastics Testing Standards **1. Executive Summary:** This report analyzes a notification from the Bureau of Indian Standards (BIS) regarding Indian standards for plastics testing, specifically focusing on optical properties. The notification establishes a new standard, IS 13360 Part 9 Sec 9: 2025, and simultaneously indicates the concurrent validity and subsequent withdrawal of the older standard, ISO 17223: 2014. This amendment aims to update the methodology for determining the yellowness index of plastics, likely reflecting advancements in testing procedures or alignment with updated international standards. The key change involves replacing the older ISO standard with a revised Indian Standard, ensuring manufacturers adhere to the updated procedures defined by the BIS. **2. Introduction:** This report aims to provide information regarding a notification published by the Bureau of Indian Standards (BIS) concerning standards for plastics testing. The analysis is based solely on the provided text of the notification. **3. Policy Overview:** This notification constitutes an amendment to the existing framework of Indian Standards by updating or replacing a specific standard. * **Core Objective(s):** The core objective, inferred from the text, is to update and revise the standards related to testing the optical properties of plastics, specifically regarding the determination of the yellow index and change in yellowness index. The aim is to transition from ISO 17223:2014 to the updated Indian Standard IS 13360 Part 9 Sec 9: 2025. **4. Background and Rationale:** This notification represents an amendment likely driven by the need to update and improve existing testing methodologies. The replacement of ISO 17223:2014 with IS 13360 Part 9 Sec 9: 2025 suggests a revision of the methods used for determining the yellowness index of plastics, possibly to incorporate technological advancements, address identified shortcomings in the previous standard, or align with evolving industry best practices. The rationale is to ensure consistent and up-to-date quality control measures within the Indian plastics manufacturing sector. **5. Key Provisions / Changes:** This notification introduces the following key changes: * **Specific Part of Original Policy Changed:** The standard for determining the yellowness index of plastics is being updated, superseding the ISO 17223:2014. * **New Rule/Provision:** The notification establishes IS 13360 Part 9 Sec 9: 2025 as the new Indian Standard for "Plastics Methods of Testing Part 9 Optical Properties Section 9 Determination of Yellow Index and Change in Yellowness Index First Revision". This standard has been established on June 09, 2025. * **Difference/Effect of Change:** The effect of this change is that manufacturers and testing laboratories within India will be required to adopt the procedures outlined in IS 13360 Part 9 Sec 9: 2025 for determining the yellowness index of plastics. The ISO 17223: 2014 will remain in force concurrently until December 09, 2025 and thereafter will be withdrawn. **6. Target Audience and Stakeholders:** Based on the text, the target audience and stakeholders directly affected by this amendment include: * Manufacturers of plastics and plastic products in India. * Testing laboratories involved in the quality control and certification of plastics. * Organizations and individuals involved in setting and enforcing Indian standards for plastics. * The Bureau of Indian Standards (BIS) itself, as the responsible body for implementing and overseeing the changes. **7. Implementation Aspects (Inferred):** Based on the text, the following can be inferred about implementation: * **Responsible agency/bodies:** The Bureau of Indian Standards (BIS) and the Department of Consumer Affairs are the responsible bodies. * **Timelines:** The Indian Standard IS 13360 Part 9 Sec 9 : 2025 was established on June 09, 2025. The ISO 17223 : 2014 will be withdrawn on December 09, 2025. This implies a transition period where both standards are valid. * **Procedures:** The specific procedures are not detailed in the notification itself, but are contained within the document IS 13360 Part 9 Sec 9: 2025. **8. Expected Outcomes / Impact of Changes:** The likely intended outcome of these changes is to ensure: * **Standardized Testing:** Increased consistency and accuracy in determining the yellowness index of plastics through the adoption of the revised Indian Standard. * **Quality Control:** Enhanced quality control measures within the Indian plastics manufacturing industry. * **Compliance:** Compliance by manufacturers with the updated standards set by the Bureau of Indian Standards. * **International Alignment:** Possible better alignment with current international best practices in plastics testing. **9. Conclusion:** The BIS notification represents a focused update to the standards governing plastics testing in India. By establishing IS 13360 Part 9 Sec 9: 2025 and phasing out ISO 17223:2014, the BIS aims to improve the accuracy and consistency of yellowness index determination for plastics. This change will likely have a significant impact on manufacturers and testing laboratories, requiring them to adapt to the new standard by December 9th, 2025. This demonstrates the BIS's commitment to maintaining relevant and updated standards for the plastics industry.
