Part 1 of ISO 80000 introduces the International System of Quantities and describes its relationship with the International System of Units (SI). Specifically, its introduction states "The system of quantities, including the relations among the quantities used as the basis of the units of the SI, is named the International System of Quantities, denoted 'ISQ', in all languages." It further clarifies that "ISQ is simply a convenient notation to assign to the essentially infinite and continually evolving and expanding system of quantities and equations on which all of modern science and technology rests. ISQ is a shorthand notation for the 'system of quantities on which the SI is based'."

The harmonized IEC 80000-13:2008 standard cancels and replaces subclauses 3.8 and 3.9 of IEC 60027-2:2005, which had defined the prefixes for binary multiples. The only significant change in IEC 80000-13 is the addition of explicit definitions for some quantities. Since 1 April 2020, there have been 1,244 monitoring visits to 935 children’s homes of all types. These homes represented 35% of all children’s homes open at 31 March 2021. Table 3: The number of children’s homes and the number of places as at 31 March 2021 by region RegionThere were 13 secure children’s homes as at 31 March 2021. When operating at full capacity, they offer 234 places. The COVID-19 pandemic impacted on the staffing of secure children’s homes, with staff becoming ill and/or having to self-isolate. This meant that secure children’s homes could not look after as many children, as they must operate with sufficient staffing levels to provide safe care for children. We have published revised data covering children’s homes in the period 1 April 2020 to 31 August 2020 as part of this release.

Of the 13 secure children’s homes, 12 were run by LAs. The remaining one was run by a voluntary organisation. IEC 80000-13:2008 was reviewed and confirmed in 2022 and published in 2008, and replaced subclauses 3.8 and 3.9 of IEC 60027-2:2005 and IEC 60027-3. [15] Table 6: The number and percentage of newly registered and closed children’s homes in 2020 to 2021, split by region Region The 63 restrictions of accommodation occurred in 54 different children’s homes in 2020 to 2021, with 9 homes receiving multiple restrictions of accommodation in year. One of these homes was later cancelled by Ofsted.

Example of Long Divisions

On 31 March 2021, there were 2 secure training centres operating. Since then, the Ministry of Justice has announced that all children are to be removed from one of these secure training centres due to serious safety concerns. As with children’s homes, we have continued to regulate and register other social care providers throughout the pandemic. Of the 346 new children’s homes, 56 (16%) were owned by 8 of the top 10 largest children’s homes providers. CareTech Holdings Plc registered 18 of these homes and SC Topco Limited registered 10. These 56 children’s homes accounted for 14% (161) of all new places. More detailed data on ownership, exploring beyond the top 10 children’s home providers, will be available in the national social care providers management information being published at the end of July 2021.
