The Department of Trade and Industry’s Bureau of Philippine Standards (DTI-BPS) adopts International Organization for Standardization (ISO) 4148:2019 Road vehicles – Special warning lamps – Dimensions, as Philippine National Standard (PNS).

The PNS ISO 4148:2019 was approved for adoption as PNS by the DTI-BPS upon the recommendation of the Technical Committee on Road Vehicles (BPS/TC 44). This standard specifies the dimensions of special warning lamps for road vehicles, in order to ensure interchangeability and accurate positioning, bearing in mind the rapid change of light intensity from such devices in a vertical cross-section of the projected beam.

BPS/TC 44 is composed of representatives from the Coalition of Clean Air Advocates of the Philippines; Philippine Parts Maker Association; University of the Philippines Diliman - National Center for Transportation Studies; Automobile Association of the Philippines; Electric Vehicle Association of the Philippines; Eclimo Electric Management, Inc.; Chamber of Automotive Manufacturers of the Philippines; Motorcycle Development Program Participants Association Inc.; Truck Manufacturers Association; Philippine Society for Mechanical Engineers; Safety Organization of the Philippines, Inc.; Department of Science and Technology’s Metals Industry Research and Development Center, and Philippine Council for Industry, Energy and Emerging Technology Research and Development; Department of Energy - Energy Utilization and Management Bureau; Technical Education and Skills Development Authority; Land Transportation Office; Board of Investments; and National Anti-Poverty Commission -  Persons with Disability Sector.

The DTI-BPS also adopted the following standards on road vehicles as Philippine National Standards:

1. PNS ISO 7747:2019 Road vehicles – Filter elements for full flow oil filters – Dimensions
2. PNS ISO 7654:2019 Road vehicles – Spin-on fuel filters for diesel engines – Mounting and connecting dimensions
3. PNS ISO 7311:2019 Diesel engines – Heads for fuel filters with vertical flange – Mounting and connecting dimensions
4. PNS ISO 7310:2019 Diesel engines – Heads for spin-on fuel filters with horizontal flange – Mounting and connecting dimensions
5. PNS ISO/PAS 22574:2019 Road vehicles – Brake linings frictions materials – Visual inspection
6. PNS ISO 15484:2019 Road vehicles – Brake lining friction materials – Product definition and quality assurance
7. PNS ISO 11530:2019 Road vehicles – Hydraulic jacks – Specifications
8. PNS ISO 4082:2019 Road vehicles – Motor vehicles – Flasher units

10. PNS ISO 4929:2019 Road vehicles – Diaphragm gaskets for hydraulic brake master cylinder reservoirs using a non-petroleum base hydraulic brake fluid
11. PNS ISO 4930:2019 Road vehicles – Elastomeric seals for hydraulic disc brake cylinders using a non-petroleum base hydraulic brake fluid (Service temperature 150 degrees C max)
12. PNS ISO 6118:2019 Road vehicles – Elastomeric cups and seals for cylinders for hydraulic braking systems using a non-petroleum base hydraulic brake fluid (Service temperature 70 degrees C max)
13. PNS ISO 6119:2019 Road vehicles – Elastomeric seals for hydraulic disc brake cylinders using a non-petroleum base hydraulic brake fluid (Service temperature 120 degrees C max)
14. PNS ISO 7631:2019 Road vehicles – Elastomeric cups and seals for cylinders for hydraulic braking systems using a petroleum base hydraulic brake fluid (Service temperature 120 degrees C max)
15. PNS ISO 7632:2019 Road vehicles – Elastomeric seals for hydraulic disc brake cylinders using a petroleum base hydraulic brake fluid (Service temperature 120 degrees C max)

These standards will promote common understanding among stakeholders of the road vehicles industry.

The DTI-BPS is the National Standards Body of the Philippines. It is the country’s member to the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC).
