Laundry symbol

A laundry symbol, also called a care symbol, is a pictogram indicating the manufacturer's suggestions as to methods of washing, drying, dry-cleaning and ironing clothing. Such symbols are written on labels, known as care labels or care tags, attached to clothing to indicate how a particular item should best be cleaned. While there are internationally recognized standards for the care labels and pictograms, their exact use and form differ by region. In some standards, pictograms coexist with or are complemented by written instructions. GINETEX, the France-based European association for textile care labelling, was formed in 1963 in part to define international standards for the care and labelling of textiles. By the early 1970s, GINETEX was working with ISO to develop international standards for textile labelling, eventually leading to the ISO 3758 standard, Textiles – Care labelling code using symbols. ISO 3758 was supplemented in 1993, revised in 2005 and again in 2012 with reviews of the standard held on a five-year cycle. In March 1970, the Canadian Government Specification Board published 86-GP-1, Standard for Care Labelling of Textiles, which promoted a symbol-based textile care labelling system in which symbols were colored: green indicated "no precautions are necessary", yellow indicated "some caution is necessary", and red indicated "prohibited". Publication 86-GP-1 was revised several times over the following three decades; the most noteworthy change was in 1979, when temperatures changed from Fahrenheit to Celsius, and any additional instructions were to be added in text, in both English and French. In 2003, the system was withdrawn in favor of a black-and-white symbol-based system harmonized with North American and international standards. The inclusion of care symbols on garments made or sold in Canada has always been voluntary; only fabric content labels are mandatory (since 1972). In 1996, in the United States, ASTM International published a system of pictorial care instructions as D5489 Standard Guide for Care Symbols for Care Instructions on Textile Products, with revisions in 1998, 2001, 2007, 2014, and 2018.
