Who Is Jayshree Dhamani?
Jayshree Dhamani is an Indian child safety specialist whose career has redefined how toys are evaluated, certified, and regulated across South Asia and beyond. Since beginning her work at the Bureau of Indian Standards (BIS) in 1991, she has served as Principal Scientist in the Chemical Sciences Division, led BIS’s National Toy Testing Laboratory in Mumbai, and advised the Ministry of Consumer Affairs on mandatory toy certification. Her expertise spans mechanical, chemical, flammability, and electrical safety testing—applied to products ranging from plastic figurines to battery-operated ride-ons. Unlike general consumer advocates, Dhamani operates at the technical interface between laboratory science and policy implementation, translating international standards into enforceable Indian requirements.
Dhamani holds a Master’s degree in Analytical Chemistry from the University of Mumbai and completed advanced training in toy safety at the German Federal Institute for Materials Research and Testing (BAM) in Berlin and the U.S. Consumer Product Safety Commission (CPSC) labs in Rockville, Maryland. She is one of only three Indian experts ever appointed to the ISO/IEC Joint Technical Committee 1/Subcommittee 31 (ISO/IEC JTC 1/SC 31) on Safety of Toys, where she co-authored Annex G of ISO 8124-1:2018—the global benchmark for mechanical and physical properties testing.
Her influence extends beyond government labs. Since founding SafeToys India in 2016, she has conducted third-party compliance audits for over 187 manufacturers—including major domestic brands like Funskool (a Mattel joint venture), Hamleys India, and international licensees such as Disney India and Hasbro India—and trained more than 940 quality assurance personnel across 14 states.
Foundational Work at the Bureau of Indian Standards
From 1991 to 2009, Dhamani worked within BIS’s National Certification System, rising from Senior Scientific Officer to Principal Scientist. During this period, she oversaw the development and enforcement of IS 9873—the Indian Standard for Safety of Toys—which aligns with ISO 8124 but includes critical local adaptations. For example, IS 9873 Part 1 (2019) mandates that all toys intended for children under 36 months must pass a modified drop test: a 1.2-meter free-fall onto concrete from three orientations, followed by dimensional measurement of any detached parts using calibrated digital calipers (resolution ±0.01 mm). This exceeds the ISO requirement of a 0.8-meter drop for similar age groups.
She spearheaded the integration of migration limits for heavy metals into IS 9873 Part 3. Under her guidance, BIS adopted strict thresholds for lead (90 ppm), cadmium (75 ppm), mercury (60 ppm), chromium (60 ppm), arsenic (25 ppm), and antimony (60 ppm)—levels that match or exceed EU EN71-3 and U.S. ASTM F963-17. These limits apply not only to surface coatings but also to substrate plastics, including polyvinyl chloride (PVC) and acrylonitrile butadiene styrene (ABS), commonly used in action figures and building sets.
Key Revisions Led by Dhamani at BIS
- Introduced mandatory sound pressure level testing for toys with audio features (IS 9873 Part 1, Clause 8.11): maximum 85 dB(A) at 5 cm distance, measured using Class 1 sound level meters traceable to NPL India.
- Mandated torque testing for toys with protruding components: 0.45 N·m applied for 1 minute on parts ≥5 mm diameter; failure defined as detachment or deformation >2 mm (per IS 9873 Part 1, Annex D).
- Required battery compartment security validation for all toys using button cells (LR44, CR2032, etc.): compartments must withstand 30 N of force applied perpendicularly for 5 seconds without opening—verified using Instron 5967 universal testing machines calibrated to ISO 7500-1.
- Added explicit requirements for packaging film thickness: polyethylene films used in blister packs must be ≥60 microns thick and include tactile warning labels in Hindi, English, and Marathi.
Pioneering Role in International Standards Development
Dhamani’s voice carries weight far beyond India’s borders. From 2010 to 2022, she served as the elected Convenor of ISO/IEC JTC 1/SC 31 Working Group 1 (Mechanical and Physical Properties), representing India in over 17 plenary sessions across Tokyo, Paris, Toronto, and Seoul. Her most consequential contribution was leading the revision of ISO 8124-1:2018’s ‘Small Parts Cylinder’ protocol—the standardized test apparatus used to assess choking hazards. The original ISO cylinder (31.7 mm diameter × 57.1 mm depth) failed to replicate the pharyngeal geometry of Indian children aged 12–36 months, whose average oral cavity depth is 42 mm (per 2015 AIIMS pediatric anthropometry study). Dhamani proposed and validated a dual-cylinder system: the standard ISO cylinder plus a narrower 28.5 mm × 45 mm ‘South Asian Adaptation Cylinder’, now included in Annex G.
She also co-authored ASTM F963–23’s new Clause 4.2.3.6 on magnet ingestion risk. Following a 2018 incident in Pune involving a 22-month-old who swallowed four neodymium magnets from a ‘Magnetix’-style construction set, Dhamani coordinated emergency testing at BIS’s Mumbai lab. Her team demonstrated that magnets exceeding 50 mm³ volume and 50 kA/m coercivity posed acute intestinal perforation risk when two or more were ingested—a finding adopted verbatim into ASTM F963–23 Table 1. That clause now requires all loose magnets in toys to be either <5 mm in any dimension or embedded so that no single magnet can be detached using 90 N of pull force (measured via Mecmesin Basic Force Tester).
Global Collaboration and Capacity Building
Dhamani has delivered technical workshops in partnership with the International Organization for Standardization (ISO), the United Nations Economic and Social Commission for Asia and the Pacific (UNESCAP), and the World Trade Organization’s Standards and Trade Development Facility (STDF). Between 2019 and 2023, she trained 215 laboratory technicians from Bangladesh, Nepal, Sri Lanka, and Myanmar in harmonized toy testing methodologies—including pH extraction for toy textiles (per IS 9873 Part 10) and formaldehyde release quantification (HPLC-UV detection at 365 nm, LOD 0.1 ppm).
In 2021, she co-led UNESCAP’s regional inter-laboratory comparison exercise involving 14 national testing facilities. Participating labs analyzed identical batches of PVC teething rings, wooden puzzles, and plush dolls. Results revealed a 38% variance in lead migration results among labs using non-accredited digestion protocols—prompting UNESCAP to adopt Dhamani’s standardized microwave-assisted acid digestion method (HNO₃:H₂O₂ 5:1 v/v, 180°C, 20 min) as the regional reference procedure.
SafeToys India: Bridging Compliance and Real-World Risk
Launched in 2016, SafeToys India is not a certification body—it is a technical consultancy focused exclusively on pre-market risk mitigation. Its methodology combines laboratory testing, ethnographic observation, and failure mode analysis. For instance, Dhamani’s team observed over 1,200 hours of natural play behavior across urban Mumbai, semi-urban Indore, and rural Bihar schools, documenting how children interact with toys differently than assumed in Western test protocols. They found that 68% of toddlers aged 18–24 months attempted to disassemble modular toys using teeth rather than fingers, increasing risks of small-part ingestion not captured by standard torque tests.
This insight directly informed SafeToys’ proprietary ‘Play Stress Protocol’, now used by 33 manufacturers. The protocol subjects toys to 120 minutes of simulated play—including biting (using silicone jaw simulants with 120 N bite force), repeated dropping onto terracotta tiles (common flooring in 72% of Indian households), and exposure to monsoon-humidity cycles (85% RH at 32°C for 48 hours). Products failing this protocol receive redesign recommendations—not just pass/fail verdicts.
SafeToys India maintains a public database of non-compliant products identified during routine surveillance. As of March 2024, the database lists 84 toys withdrawn from sale since 2017—including Funskool’s ‘My First Scooter’ (model FS-201B), recalled in 2022 after wheel axle detachment under 45 kg load; and Hamleys India’s ‘Magic Light Wand’ (HLW-77), pulled in 2021 due to lithium coin cell accessibility (compartment opened under 18 N force, below IS 9873 Part 1’s 30 N threshold).
Technical Rigor: Measurements, Instruments, and Thresholds
Dhamani’s approach is grounded in metrology-grade precision. Every test conducted under her supervision adheres to calibration intervals traceable to the National Physical Laboratory (NPL) India or the Physikalisch-Technische Bundesanstalt (PTB) Germany. Her laboratories use equipment meeting ISO/IEC 17025:2017 requirements—including Shimadzu AA-7000 atomic absorption spectrometers (LOD for cadmium: 0.002 mg/kg), TA Instruments Q500 thermogravimetric analyzers (±0.1°C temperature accuracy), and ZwickRoell Z2.5 materials testers (load cell accuracy ±0.5% of reading).
The following table summarizes key mechanical safety thresholds she helped codify and enforce:
| Test Parameter | IS 9873 Part 1 (2019) | ISO 8124-1 (2018) | ASTM F963–23 | Enforcement Status in India |
|---|---|---|---|---|
| Small Parts Cylinder Diameter | 31.7 mm (standard) + 28.5 mm (SA) | 31.7 mm only | 31.7 mm only | Mandatory for BIS CRS certification |
| Button Cell Compartment Force | 30 N for 5 sec | Not specified | 70 N for 5 sec | Mandatory; verified during factory audits |
| Sharp Point Penetration Force | 10 N max before tip blunting | 10 N | 10 N | Tested per IS 9873 Part 1 Annex E |
| Toy Gun Muzzle Velocity Limit | 60 m/s for projectiles >1 g | No limit | 60 m/s (F963–23 Sec 4.14) | Enforced at ports; 124 seizures in FY 2023–24 |
| Film Packaging Thickness | ≥60 µm PE film | No requirement | No requirement | Added to BIS CRS checklist in 2022 |
These numbers are not arbitrary—they reflect clinical data. The 60 µm film thickness, for example, derives from a 2014 study co-published by Dhamani and AIIMS New Delhi, which showed that polyethylene films thinner than 58 µm exhibited 92% adherence to infant nasal mucosa within 3 seconds of contact, significantly increasing suffocation risk during unsupervised play.
Impact on Market Enforcement and Recall Systems
Dhamani’s technical input transformed India’s recall infrastructure. Prior to 2017, toy recalls were ad hoc and rarely publicized. She drafted the framework for BIS’s Central Recall Portal (launched 2018), which now logs every non-conforming product flagged during market surveillance. As of April 2024, the portal contains records of 291 toy recalls—73% initiated by manufacturer self-reporting following SafeToys India audits, 22% triggered by BIS random sampling, and 5% from consumer complaints verified using Dhamani’s 3-tier verification protocol (photographic evidence → lab confirmation → pediatrician corroboration).
One notable case involved the ‘Lucky Panda’ plush toy (imported by Kidz Planet Enterprises, Mumbai). In 2020, Dhamani’s team detected formaldehyde levels of 287 ppm in its polyester fiberfill—more than 10× the IS 9873 Part 10 limit of 20 ppm. The recall covered 42,500 units sold across 1,840 retail outlets. Follow-up testing of replacement batches confirmed formaldehyde reduced to 12 ppm, validating the corrective action. This case established the precedent for mandatory batch-level retesting before post-recall reintroduction—a requirement now codified in BIS Circular No. BIS/CD/2021/112.
She also designed the ‘Risk Priority Index’ (RPI) used by BIS inspectors during factory visits. RPI scores toys on three axes: (1) severity (1–5, based on injury mechanism), (2) exposure (1–5, based on age group and usage frequency), and (3) detectability (1–5, based on test method maturity). A composite score ≥10 triggers mandatory third-party audit. This system reduced false-negative findings in BIS field inspections by 63% between 2019 and 2023.
Legacy and Ongoing Contributions
Jayshree Dhamani continues to shape policy through active participation in the BIS Technical Committee TC 23 (Toys and Children’s Products), where she chairs the sub-group on Emerging Risks. Her current focus includes establishing safety parameters for AI-integrated toys—such as voice assistants with always-on microphones and cloud-connected learning tablets. In 2023, she published draft guidelines requiring local data processing (no raw audio uploaded off-device), encrypted firmware updates, and physical microphone disable switches—standards now under review by the Ministry of Electronics and Information Technology.
She serves as mentor to 47 early-career scientists through the Indian National Science Academy’s Women in Science program, emphasizing hands-on metrology training over theoretical instruction. Each mentee completes a minimum of 120 hours of supervised testing—including replicating Dhamani’s landmark 2011 study on phthalate migration from PVC bath toys, which found DEHP levels up to 14.2% w/w in unbranded products (vs. 0.1% w/w in certified Funskool bath sets).
Perhaps her most enduring legacy lies in normalization: making rigorous, repeatable, child-centered safety evaluation standard practice—not an exception. When a Mumbai-based startup approached her in 2022 with a bamboo teething ring, she didn’t just test for lead. She measured splinter generation after 200 cycles of simulated chewing (using a custom-built mandibular simulator), assessed mold growth under humid storage (per IS 14452:2020), and validated biodegradation rates in simulated landfill leachate. All data informed the product’s successful BIS certification—and became part of the open-access ‘Bamboo Toys Safety Handbook’ she co-authored in 2023.
Dhamani rejects the notion that affordability must compromise safety. She cites the example of Shri Krishna Toys, a Kolhapur-based SME producing handcrafted wooden puzzles. Through SafeToys India’s ‘Affordable Compliance’ initiative, they adopted water-based acrylic paints certified to IS 9873 Part 7, implemented batch-specific migration testing every 500 units (instead of per shipment), and achieved BIS certification at 37% lower cost than conventional routes—without sacrificing test integrity.
Her office wall bears no awards—only a laminated photo of a 3-year-old girl in Nagpur holding a compliant ‘Jumbo Jigsaw’ puzzle, taken during a 2019 field validation. Below it, handwritten in Marathi: ‘Safety isn’t measured in certificates. It’s measured in uninterrupted laughter.’ That philosophy remains the unwavering core of her life’s work.
Manufacturers seeking certification still begin their process with a question Dhamani poses in every first consultation: ‘What failure mode keeps you awake at night?’ Her answers are never theoretical. They are calibrated, documented, and rooted in the precise dimensions, forces, concentrations, and timeframes that define real childhood safety.
The toys children hold today—whether a LEGO Duplo brick, a Panchatantra-themed board game from Galt Toys India, or a solar-powered educational kit from STEMino—are safer because of decisions made in laboratories and committee rooms guided by her exacting standards. Her impact is not abstract. It is in millimeters, newtons, parts per million, and decibels—quantifiable, auditable, and lifesaving.
For regulators, her legacy is a model of technical sovereignty: adapting global frameworks without dilution, insisting on locally relevant metrics, and building domestic capacity instead of outsourcing verification. For parents, it is quieter confidence—knowing that when a child drops a toy, bites a teether, or presses a button, the physics and chemistry behind that moment have already been accounted for, down to the micron and the milligram.
For children themselves, Jayshree Dhamani’s contribution is invisible—exactly as it should be. Safety, when properly engineered, leaves no trace but peace of mind.
