Foreword This Malaysian Standard was developed by a Technical Committee on Lighting, Lamps and Accessories under the authority of the Industry Standards Committee on Electrical and Electronics Equipments and Accessories. Major modifications in this revision are as follows: a) the title has been changed to Ballasts for tubular fluorescent lamps - Part 2: Performance

(Watt loss) requirements; b) the scope has been changed as in clause 1; c) subclauses 3.1, 3.2, 4.1 and 4.2 have been deleted; d) clauses 5, 6, 7, 8, 9, 10, 11, 12 and 13 have been deleted; and e) Annexes A, B, C and D have been deleted. This Malaysian Standard cancels and replaces, MS 141:Part 2:1993, Specification for ballasts for tubular fluorescent lamps - Part 2: Performance requirements (First revision). Compliance with a Malaysian Standard does not of itself confer immunity from legal obligations.

Ballasts for tubular fluorescent lamps - Part 2: Performance (Watt loss) requirements

1 Scope This Malaysian Standard specifies performance requirements for ballasts loss excluding resistance types, for use on a.c. supplies up to 1 000 V at 50 Hz or 60 Hz, associated with tubular fluorescent lamps with pre-heated cathodes operated with or without a starter or starting device and having rated wattages, dimensions and characteristics as specified in MS IEC 60081 and MS IEC 60901.

2 Normative references The following referenced documents are indispensable for the application of this standard. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. MS IEC 60081, Double-capped fluorescent lamps - Performance specifications MS IEC 60901, Single-capped fluorescent lamps - Performance specifications MS IEC 60921, Ballasts for tubular fluorescent lamps - Performance requirements MS IEC 61000-3-2, Electromagnetic compatibility (EMC) - Part 3-2: Limits - limits for harmonic current emissions (Equipment input current 16 A per phase) MS IEC 61347-1, Lamp controlgear - Part 1: General and safety requirements MS IEC 61347-2-8, Lamp controlgear - Part 2-8: Particular requirements for ballasts for fluorescent lamps

3 General notes on tests 3.1 One specimen shall be submitted to all tests. 3.2 In general all tests are made on each type of ballast or, where a range of similar ballasts is involved, for each rated wattage in the range or on a representative selection from the range as agreed with the manufacturer. 3.3 The test conditions specified in Annex A of MS IEC 60921, is applied together with the requirements of clause 5. 3.4 All ballasts specified in this standard shall comply with the requirements of MS IEC 61347-2-8, MS IEC 60921 and MS IEC 61000-3-2.

4 Marking Watt loss shall be marked either on the ballast or be made available in the manufacturers catalogue or the like.

5 Watt loss The watt loss, when determined by the test method in Annex A, shall not exceed the marked value by more than 10 %, except where a tolerance of less than 10% is marked, in which case, this value shall be used to determine compliance.

Annex A (normative)

Watt loss test

A.1 The circuit shown in Figures A.1 shall be used for the determination of watt loss.

A.2 The watt loss is determined by subtracting the lamp power from the total power consumed.

A.3 Test method A.3.1 General The sequence described below shall be followed. A.3.2 Reference lamp stability (see clause A.1.4 of MS IEC 60921). With the stabilised power on, position the selector switch #1 and selector switch #2 at position #1. Allow the lamp to stabilise. After the lamp has stabilised move selector switch #2 to position #2. Record the readings for the followings: a) lamp voltage; b) lamp current; and c) lamp power. Check immediately that the readings obtained are the characteristics of a reference lamp. A.3.3 Measurement of lamp power Position selector switch #1 to position #2 and record the readings for the following: a) lamp voltage; b) lamp current; and c) lamp power. A.3.4 Measurement of total power consumed Position selector switch #2 to position #2 and record the readings for the total power consumed.
