of the materials for scaffold boards are no longer in use
Under discussion for withdrawal SS 187 : 1978 SPECIFICATION FOR QUALIFICATION TEST FOR MANUAL METAL-ARC WELDERS This standard is proposed for withdrawal without replacement as a result of a survey indicating the low usage of the standard. The Singapore Welding Society had confirmed that this standard no longer has its industrial relevance and the industry is currently using various existing American and British standards.
SS 204 : 1978 SPECIFICATION FOR COVERED ELECTRODES FOR THE MANUAL METAL-ARC WELDING OF CARBON AND CARBON MANGANESE STEELS This standard is proposed for withdrawal without replacement as a result of a survey indicating the low usage of the standard.
