新规范在第一章总则中规定:高级装饰工程施工前,应预先做出样板(一个样品或标准间),并经有关单位鉴定后,方可进行。在总则中还明确其它等级的装饰工程如需做样板,应由设计确定,并在施工图中注明,以便施工单位有所依据。此外,还有些装饰工程,如水磨石、油漆等,施工前应预先配料、 The new specification stipulates in the first chapter general rules that before the construction of a high-grade decoration project, a model (a sample or a standard room) should be prepared in advance, and it can be carried out after the identification by the relevant unit. It is also clarified in the General Regulations that if other types of decoration works need to be modeled, they should be determined by the design and noted in the construction drawings so that the construction unit can have a basis. In addition, there are also decorative works such as terrazzo, paint, etc., which should be pre-mixed before construction.
