1 COUNTRY REPORT: MEASUREMENT UNITS STANDARDS AND SERVICES DEPARTMENT(MUSSD) SRI LANKA PRESENTED BY: R.G.S.ANURADHA. PERERA

2 SRI LANKA Government type: Democratic Socialist Republic Location: South Asia, Capital city: Sri Jayawardenapura Area: 65,610 sq km, Population: 20,653,000 Religion: Buddhist (69.3%); Hindu (15.5%); Muslims (7.5%); Christianity (6.9%), other (0.8%) Languages: Sinhala, Tamil, English Climate: tropical and warm / 25 C - 30 C Natural Resources: Granite, Gems, phosphate, Dolomite, Mineral sand, Sea around the island (Fish, salt, etc..) Main industries: Plantations and Agriculture (Rice, Tea, Rub ber, Coconut, Cinnamon, coffee, Sugar), Garment & Apparel, Construction sector, Food production & Processing

3 MEASUREMENT UNITS, STANDARDS AND SERVICES DEPARTMENT Measurement Units, Standards & Services Department (MUSSD) was established in 1997 to implem ent the Measurement Units Standards & Services Act No 35 of (The department earlier estab lished as weights and measure division of the department of Internal trade which was established i n 1952 to implement weights and measure ordinance No 37 of 1946 engaged mainly on legal met rology) The Act Empowers MUSSD to engage in, Fundamental metrology Industrial metrology Legal metrology In 1976, National Metric Conversion Law was established to realize the Units based on International System (SI units). In 2007 MUSSD singed the International Mutual Recognition Agreement (MRA) between National Metrology Institutes (NMIs). Regulation (related to T&F) 2011-Sri Lanka Standard time.

4 INTERNATIONAL ACTIVITIES Associate member of CGPM Member of APMP Member of OIML Signatory of CIPM MRA ( The CIPM MRA was signed on: 14 November 2007)

5 CURRENT DEVELOPMENTS OF MUSSD Contraction of new MUSSD building complex: Scientific, Calibration Laboratory buildings, Administration and Legal metrology buildings has been completed (Phase 1) (Started in 2014 January and completed in 2015 December) Shifted and started the work on 8 th December Accreditation and CMC Publication: Accreditation of Temperature, Volume, Pressure, Length, Time and Frequency, and Electrical parameters started (Quality manual management requirements already completed, Technical requirements and CMC calculation under development) (Consultancy from APMP received for Pressure laboratory and Consultancy from PTB Germany received for temperature laboratory. Starting New Fields: Establishment of Gas Standards, Chemical laboratory and Photometry laboratories has ben initiated

6 NEW MUSSD LABORATORY BUILDING COMPLEX 2015 DECEMBER 08 Location: Pitipana, Mahenawatta, Homagama, Sri Lanaka Shifted to new laboratory on

7 TIME AND FREQUENCY LABORATORY Equipment Time and Frequency Standard system: Cs Primary frequency standard (Micro semi 5071A Cs primary frequency standard), Rubidium Atomic standard (Fluke 910R GPS Controlled Rubidium Reference Clock), Time interval counter with rubidium oscillator (Fluke PM 6681R Rubidium Frequency Reference/Counter/Calibrator) Time dissemination system: NTP time servers stratum 1 and 2(LAN time M600GPS/MRS NTP Stratum 1Time Server), web server for time display Time transfer system: GNSS receiver (Polar RX4-TR), Choke ring antenna Time and Frequency calibration system: Signal Generator, Digital Storage Oscilloscope, Timer and Stopwatch calibration software with NTP server Staff Two Metrologists (MSC, Physics Special), two experimental officers (BSc Degree with Physics as a final year subject), one Lab helper (GCE. A/L) ( Shared responsibilities with other one laboratory)

8 TIME AND FREQUENCY STANDARD AND DISSEMINATION SYSTEM EQUIPMENT Fluke 910R GPS Controlled Rubidium Reference Clock Fluke PM 6681R Rubidium Frequency Reference/Counter/Calibrator Meinberg LAN time M600MRS NTP Stratum 1Time Server Meinberg LAN time M600GPS NTP Stratum 1Time Server Two web servers with stratum 2 NTP servers to maintain the time information website. GNSS Receiver (Septrintrio polar RX4TR), 3 pulse and frequency distribution amplifiers Microsemi 5071A Cs primary frequency standard

9 Time transfer system GPS Antennas for NTP system NTP Time servers T&F Laboratory Equipment Cs Primaary frequency standard

10 CURRENT ACTIVITIES OF TIME AND FREQUENCY LABORATORY Maintaining and disseminating Sri Lanka Standard Time (Regulation: Sri Lanka Standard Time Regulation 2011) Maintaining National standard for frequency Calibration services to industry and calibration, testing and medical laboratories (Stopwatches, timers, rpm meters, centrifuges, function generators, oscilloscopes, other timing and time interval measuring instruments used in government authorities and industry) (Number of calibrations: 65 items/year)

11 CURRENT PLANS Establish CMCs for time interval and frequency parameters (By 2018) Participate for regional Time and frequency inter comparisons (Plan to start in 2016) Established time and frequency standards and to participate for determining UTC, (purchasing necessary equipment, Technical support from other NMIs) (2016 to 2020) Train more staff members and raise awareness about T&F field to increase research activities combine with other NMIs and international and local institutes and universities. Establishing a time stamping service combine with the intellectual property registration department( 2017 to 2018). Studying and developing n time and frequency dissemination methods.(2017 to 2018)

12 PROBLEMS DIFFICULTIES Lack of experience on equipment used in GPS Time transfer GNSS receiver internal delay calibration
